Low-Profile Rotary Stage has overall height of 41.5 mm.

Driven by preloaded 180:1 worm gear, 193 mm long DT 58-DC series achieves speeds up to 80Ã-

High-Speed Ball Screws have elastic spacers.

With design that avoids inter-ball friction and torque build-up at slow speeds, UltraSpeed KES ball nut incorporates spacers between balls and plastic tubes in recirculating channels. It also features dual ball return systems with deflectors that guide balls in tangential direction, away from shaft and into return channels integrated inside nut body. With dn rating of 160,000, product is capable...

Ball Screws offer dynamic ratings up to 1 mil N.

UltraThrust Precision Ground Ball Screws are offered in 50 x 20, 63 x 20, 63 x 30, 80 x 20, 80 x 40, and 100 x 20 mm sizes, all with 15 mm load carrying balls. UltraThrust 63 x 20 mm ball screw offers dynamic capacity of 430 kN, compared with 179 kN for standard series 1416 ball nut, which uses 11 mm balls. UltraThrust ball screws are suited for very large transfer line modules or to replace...

Ball Screws feature elastic spacer technology.

Ball Screws use elastic spacers to separate recirculating balls inside nut, allowing them to achieve extremely fine and slow motion consistently. When nut is fully assembled, slight compression of each elastic spacer between 2 adjacent balls ensures sustained close guidance during recirculation inside nut. Hole in middle of spacer allows adjacent balls to touch in event of jamming, preventing...

Ball Screws are offered in 11 sizes.

Engineered for smooth, quiet motion at high speeds, Quiet Ball Screws minimize noise because nut uses end cap ball returns machined from plastic. Offered in 6 diameters from 5-20 mm and pitches from 2-32 mm, products are available with or without backlash and in choice of 2 accuracy grades: T5 ground thread and T7 rolled thread. Steinmeyer Combination Wiper system, consisting of labyrinth seals...

Miniature Ball Screws include 3 mm size.

ULTRAMINIATURE ball screws are offered in diameters as small as 3 mm, with choice of 1 mm or 0.5 mm pitch. Made from standard tool steel, screws are hardened and precision ground to meet ISO tolerances from T0 to T5. Nut types include: Series 1112 cylindrical with attaching thread, Series 1214 cylindrical with fitting key, and Series 1412 with flange. All include preload option. Series 1510...

Ball Screws feature rotating nuts.

Ball screws with rotating nuts are suitable for automated machinery that operates at high speeds. Nuts are offered in 16 x 30, 32 x 40, and 65 x 80 sizes. Any ball nut can be modified and converted into rotating nut, by adding precisely ground bearing seat on outside diameter, together with lock nut threads.

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...
