The Acceleration Behind Your Best Ideas Slide Bush Seamless Ball Retainers. Widest Variety. The NB Slide Bush family features solid steel outer ring construction and is available with optional integral wiper seals in both high quality and precision grades. Seamless ball retainers provide smoother motion and higher rigidity. Product variety includes Lightweight, Standard, Clearance Adjustable, Open and Double-Wides. The innovative Double- Wide type offers added stability when additional moment loads are required. Slide Bush types are available in Inch and both Asian and European metric...

High Load TOPBALL is NB's premier Slide Bush, offering up to 27 times the normal travel life of a conventional slide bush. Our uniquely produced load plates incorporate ground raceway surfaces. These surfaces provide a circular arch contact for the ball resulting in greater dispersion of loads for three times the normal load capacities. TOPBALL Slide Bush is available in 3' 16 to 2 inch sizes and is fully interchangeable with conventional linear bushings. All feature self-alignment capabilities and NB's unique optional floating wiper seal. A full line of prefabricated units is also offered....

The Acceleration Behind Your Best Ideas Miniature Slide Guides Less Space Required More Load Achieved The compact design offered by NB's Miniature Slide Guide allows designers to reduce machinery size and weight. NB technology stabilizes uneven multidirectional load factors for the ultimate in smooth continuous movement. Precise high-speed operation is assured. Precision-machined steel balls, as rolling elements, promote exceptionally low resistance. This provides smooth, stable operation at low cost. The Retained Ball (SEBS-B type) allows the block to be removed from the rail, simplifying...

Ball Spline Eliminates Backlash _Reduces Friction NB's Ball Spline family is designed for mechanical applications, which may require both linear motion, combined with superior torque transmission. Recirculating steel balls on the side of the outer race allow for economy of space and high-speed rotation. Backlash is eliminated. NB provides unmatched precision with a full range of sizes and configurations, including custom, machined orders in a timely fashion. Heavy Duty High Load Stability Easy Installation The Slide Guide series is designed to maintain stability under extremely high load...

Slide Shaft Highly Precise NB offers highly precise machined shaft for use with a slide bush or as a custom component in other applications. These applications may require pipe shaft, which reduces weight (without reducing rigidity and allows for channeling). The fine shaft is mass-produced to offer lower cost and shorter lead times; and also available in inch or metric dimensions. Custom Shaft Unmatched Quality NB Slide Shaft is case-hardened heat-treated high-carbon chromium bearing steel or corrosive-resistant Martensite stainless steel for maximum performance quality. Our precision...

Adjustment Free High Rigidity Ultra Space Saving NB's BG type is a compact single axis actuator, which integrates a slide guice and precision ball screw. This eliminates complex precision adjustment and reduces installation time dramatically. The "U" shaped guide rail provides very high rigidity and can be used for one-end supported applications. High positioning accuracy is achieved by the combination of the precision ground guide rail; slide block and precision ball screw arrangements. In comparison to conventional positioning tables, the NB BG type allows for more compact designs and...
