It is mineral oil based grease containing lithium thickener and several additives. It is superb in load resistance as well as stability in oxidization. It not only maintains good lubrication over a long period of time, but also demonstrates superb capability in retaining water. Even containing a large amount of water, it does not lose grease when it is softened. Feature It is a standard grease for general NSK linear guides, ball screws and monocarriers. It is prevalently used in many applications because of its high base oil viscosity, high load resistance, and stability in oxidization. Application Range of use temperature Quantity: 80 g Tube color: Green It contains a special synthetic oil for high temperature and stability, and a carefully selected antioxidation agent. This grease dramatically increases lubrication life under high temperature conditions. It is used for high speed, medium load. Lubrication life exceeded 2 000 hours in the endurance test at 150ºC. Its rust prevention capacity in severe conditions such as water and moist environments is further strengthened. It is a standard grease for ball screws PSS type (shaft dia. 15 mm or over), FSS type and VFA type. It is ideal for operation with medium load, at high speed such as positioning in high tact material handling equipment.

Compared to the fluorine grease which are commonly used in clean room, LG2 has several advantages such as; higher in lubrication function, longer lubrication life, more stable torque (resistant to wear) and higher rust prevention. In dust generation, LG2 is more than equal to fluorine grease in keeping dust volume low. Since the base oil is not a special oil but a mineral oil, LG2 can be handled in the same manner as general greases. Feature LG2 is a lubrication grease for rolling element products such as linear guides, ball screws and monocarriers for semiconductor and liquid crystal display (LCD) processing equipment which require a highly clean environment. It is a standard grease for NSK standard ball screw USS type. * Wash the linear guides and ball screws to remove oil prior to applying Clean Grease LG2 , so the grease functions are fully utilized. * Clean grease is exclusively used for clean environments under normal pressure. Application Feature Application Hightemperature Reference no. : NSK GRS LGU Quantity: 80 g Tube color: Yellow This is a proprietary urea grease of NSK featuring low dust emission exclusively for ball screws and linear guides which are used in clean rooms. In comparison with fluorine base grease, which has been used commonly in clean rooms, LGU has better lubricating property, longer duration of lubricant, better torque variation, much better anti-rust property, and equivalent or better dust emission. In addition, this grease can be handled in the same way as the other common grease because high-grade synthetic oil is used as the base oil. LGU grease contains much less metallic elements compared to LG2 grease. It can be used in high temperature environment. This is exclusive lubrication grease for ball screws and linear guides that are installed in equipment that requires cleanliness, as same as LG2 grease, and it can be used in high temperature range. * Wash the linear guide and ball screws to remove oil prior to applying Clean Grease LGU, so the grease functions are fully utilized. * Clean grease is exclusively used for clean environments under normal pressure.

For the products not applied grease, try the system a few times (operate the ball slide of linear guide, ball nut of ball screw or monocarrier slider for whole stroke length 5 to 10 times) after supplying grease, and wipe off excess grease. Supply required amount through grease fitting by a grease pump. Wipe off old grease and accumulated dust before supplying new grease. If grease fitting is not used, or there is no holes for grease replenishment, apply grease directly to the rail or to the ball groove of the screw shaft, and move a ball slide, ball nut or monocarrier slider few strokes so the grease permeates into the ball slide, monocarrier slider and inside the nut. Once grease is replenished, another supply is not required for a long time. But under some operational conditions, it is necessary to periodically replenish grease. When replenishing using a grease pump, fill the inside of ball slide, ball nut and monocarrier slider with grease. Supply grease until it comes out from the ball slide, ball nut or monocarrier slider area. Move ball slide, ball nut and monocarrier slider by hand while filling them with grease, so the grease permeates all areas. Do not operate the machine immediately after replenishing. Always try the system a few times to spread the grease throughout the system and to remove excess grease. Trial operations are necessary because the resistance to sliding force and screw torque greatly increases immediately after replenishment (full-pack state) and may cause problems. Wipe off excess grease that accumulates at end of rail and screw shaft after trial runs so the grease does not move to other areas. Intervals of checks and replenishments Although the grease is of high quality, it gradually deteriorates and its lubrication function diminishes. Also, the grease in the ball slide, ball nut and monocarrier slider is gradually removed by stroke movement. In some environments, the grease becomes dirty, and foreign objects may enter. Grease should be replenished depending on frequency of use. The following is a guide of grease replenishment intervals. Intervals of checks Items to check Intervals of replenishments 3 - 6 months Dirt, foreign matters such as cutting chips Usually once per year. Every 3 000 km for material handling system that travels more than 3 000 km per year. Replenish if checking results warrant it necessary. How to replenish 1 Wipe off old greases on the rail and screw shaft by clean cloth. 2 Supply grease until it comes out from the ball slide or ball nut area. Move the ball slide or ball nut by hand while filling them with grease. 3 15 Full-pack state. 16 Internal space Refer to the tables below for the grease quantity of full-pack state.

Viscosity is particular high in winter due to low temperatures. Pay attention to increases in linear guide and monocarrier sliding resistance, and ball screw and monocarrier torque in such conditions. — When the ambient temperature is low, or in Winter, if it is difficult to pump out the grease from the container, wait until the grease is softened. — In locations where coolant is dispersed or scattered, emulsification of lubricants and rinsing with water may significantly deteriorate the integrity of the lubricant and the efficacy of the grease. Protect the grease unit from coolant by shielding it with a cover, etc. NSK Grease FM1（NSK GRS FM1） Quantity: 80 g Tube color: Gold Fluorochemical grease for a wide variety of uses, with superb torque characteristics at low temperatures and long-term lubrication properties at high temperatures.

NSK Grease MTS（NSK GRS MTS） Explanation of term Term Thickener Base oil A synthetic fluid, such as mineral oil, silicone oil, or diesters is used as the base oil of a grease. Since the lubrication a grease provides depends mainly on that of the base oil, the viscosity of the base oil must be as carefully selected as the lubricant. Test condition ー Consistency JIS K 2220 – 7. Drop point The temperature at which heated grease in a small, standardized container turns to a liquid state. In general, this indicates the highest temperature at which excessive separation of oil or drippings have not yet started. JIS K 2220 – 8. Evaporation rate The amount of evaporated grease in a mass percentage after maintaining the grease at a certain temperature and subjecting it to heated air for 22 hours. The lower the value, the better, since grease tends to solidify and provide poor lubrication if the amount of evaporation is high. JIS K 2220 – 10. Copper plate corrosion The result of inspecting whether a polished copper plate changes color to green or black after maintaining the plate in room temperature or 100ºC for 24 hours. Use of industry-standardized copper plates is advised. JIS K 2220 – 9. Oil releasing The amount of oil separated from grease in a metallic net after maintaining it at temperature of 100ºC for 24 hours. If the rate at which the oil is release is low, it may result in poor lubrication, and if the rate is high, the life of the grease may be shortened. JIS K 2220 – 11. The speed (duration of time) at which a base oil passes through a thin pipe due to its own weight. The value is calculated by dividing viscosity by density. Generally, high kinetic viscosity indicates better load bearing, but produces larger viscosity resistance in high-speed operations. Contains urea thickener and delivers higher heat resistance. Recommended for use with ultra high speed machine tool spindles. Allowable temperature range is -40 to +130ºC. ー The depth a cone of a standard weight reachs when dropped onto grease. Consistency indicates the hardness of grease and helps estimate the fluidity of grease when used. When viscosity is high, the grease is soft, and when viscosity is low, the grease is hard. Base oil viscosity 19 Explanation A tiny-fibrillate or granular aggregate that maintains base oil by capillary action. Metallic soap thickeners include a versatile lithium-type, while non-soap thickener include a urea-type, which is high-temperature resistant. JIS K 2283 – 5. NSK Grease MTE（NSK GRS MTE） Formulated to handle higher load capacities. Recommended for use in high speed machine tool spindles. Allowable temperature range is -20 to +130ºC.
