Only 2% of all ball screws sold in North America are manufactured here, so you’ll be able to take advantage of shorter lead times, reduced shipping costs, and enhanced communication with support and service. The FSI Style provides the best in quality, performance and delivery at a competitive price. German Engineered • DIN 69051 compliant (FSI Style 16 - 50 mm only) • Patented Precision Screw Forming (PST) technology • Smooth performance due to unique ball return systems North American Manufacturing and Technical Support • Regionally stocked/machined/assembled product - Tijuana, Mexico to support West Coast - Marengo, Illinios to support East Coast • P5 accuracy screws standard • Ground quality ball nuts www.thomsonlinear.com 3 FSI Style Application Examples Thomson’s FSI ball screw assemblies provide the smooth motion and positional accuracy typically found only in a ground product. These qualities, combined with the economical precision rolled solution, make them ideal for large 3-axis structures. Gantry Thomson’s unique ball return systems and preload capabilities reduce the effect of critical screw speed on a long slender axis (see X-axis above). Combined with the Thomson profile rail, this solution provides stiffness and accuracy to the overall system. Smooth motion is necessary to prevent reflected inertia from causing structural vibration in large structures. The illustrated Y-axis below combines a precision FSI ball screw assembly with the alignment compensation of Thomson linear rails. Engraver / Laser / Waterjet Cutting Machine tool applications have primarily been the domain of ground ball screw assemblies. The introduction of high-precision P3/P5 accuracy rolled ball screws has eliminated the need for ground product where a less expensive solution that still meets high performance standards is required. These types of applications typically require P3/P5 accuracy, 75-100% duty cycle, harsh environments, and reversing loads or dithering issues. FSI ball screw assemblies have molded rubber (NBR) seals as standard in sizes ø16 mm and above and are ideal for these demanding parameters. 4 www.thomsonlinear.com Metric Series Ball Screws Metric Ball Nut Return System Overview All ball screws require a recirculation system for the ball bearings. Thomson return systems are optimized for each diameter and lead combination to maximize load capacity, minimize footprint and guarantee smooth operation. Single Return (E = Single Liner, M = Multi Liner) For single-start ball screws After each turn, the balls are lifted from the shaft raceway and set back by a single turn. Thomson NEFF return systems made from glass-fiber reinforced plastic or steel guarantee a faultless and gentle recirculation of the balls. Internal Return (K = Channel) For single-start and multiple-start ball screws. After several turns, the balls are returned either by a patented plastic recirculation system integrated into the nut or through recirculation channels also integrated into the nut using steel recirculation inserts. External Return (D = End Cap) For multiple-start ball screws. The balls are recirculated via two special end caps and return channels integrated into the nut. www.thomsonlinear.com 5 Bearing Supports Product Overview Metric Ball Screws Diameter BK BF FK FF MK WK 12 7833391 7833398 7833405 7833411 7833700 - 16 7833392 7833399 7833406 7833412 7833701 - 20 7833393 7833400 7833407 7833413 7833702 - 25 7833394 7833401 7833408 7833414 7833703 7833614 32 7833395 7833402 7833409 7833415 - 7833615 40 7833396 7833403 7833410 7833416 - 7833617 50 7833397 7833404 - - - 7833621 BK Bearing Support (1), (2) SEAL SEAL FK Bearing Support (1), (2) SPACER SPACER SEAL SEAL SPACER SPACER ANGULAR CONTACT ANGULAR CONTACT BEARINGS BEARINGS ANGULARCONTACT CONTACT ANGULAR BEARINGS BEARINGS SPACER SPACER SEAL SEAL LOCK LOCKNUT NUT The base mounted BK Bearing Support contains an angular contact bearing pair for increased stiffness and axial load capacity.

Perfect accuracy, for example, means advancing a ball nut 25 mm from any point on a screw will always require the exact same number of revolutions. Lead Error The amount of positional error per 300 mm (Metric Series) that is inherent in linear motion on ball screws. Load/Life Rating The usable life of a ball bearing screw assembly measured in revolutions under a specific load. The revolutions that 90% of a group of ball bearing screws will complete, or exceed, before the first evidence of fatigue develops. Axial Lash / Backlash The axial-free motion between the ball nut and ball screw; a measure of system stiffness and repeatability. Column Load / Compression Load Load that would tend to compress or buckle the ball screw shaft. Dynamic Load Rating Maximum load that a ball bearing screw assembly can maintain for 1 million revolutions (Metric Series). Repeatablity A measure of constancy that is directly related to axial backlash. Higher backlash equates to lower repeatability and may be corrected by preloading the ball nut if required. Static Load Static load is the maximum non-operating load capacity above which brinelling of the ball track occurs. Lead The axial distance a screw travels during one revolution.
