Double Nut Design stops errors caused by spacers.

UNILOCK double nut design for large precision ground ball screws eliminates need for spacers or connecting hardware. Its method also eliminates backlash by using two nuts preloaded against each other and then locked using integral bonding system. With minimal number of parts, double nut eliminates angular errors in assembly of two nuts. UNILOCK system is available for ball screw diameters from 16...

Ballscrews designed for high speed machine tools.

UltraSpeed series ball screws, available in 16 to 63 mm dia, enable speed ratings to dN = 160,000. With lead to diameter ratios from 0.5:1 to 1:1, linear velocities of 4,000 ipm are possible at acceleration of 2 g and higher. Ball return system uses precision ball deflectors to guide balls into return channel spanning whole nut length. Two-piece deflectors, precision milled from steel, minimize...

Ball Screw Wiper protects against contaminants.

Combination Wiper includes friction type finger wiper in front of felt wiper. Dual wiper keeps contaminants from entering ball nut, while simultaneously lubricating ball screw. Felt doubles as lubricant reservoir, maintaining constant thin film of oil on screw thread as ball nut moves. Because minimal amount of oil is deposited on thread, ball screw oil consumption is reduced by 75%. Wiper is...
