Linear Bearings offer two quality grades for high accuracy.

Press Release Summary:

Cross-Roller Precision Linear Bearings with SQ Special Quality Option have runout of no more than 5 microns over travel distance up to 1,800 mm. They withstand high demand applications such as optical measuring equipment. SSQ Super Special Quality bearings have runout of no more than 2.5 microns over travel distance of 1,200 mm, and meet stringent requirements of fiber optic splicing equipment. Both offer extreme smoothness and zero friction.

Two New Quality Grades Support High Accuracy for Schneeberger Linear Bearings

Subject: New Product/Design Engineering/OEM Manufacturing

Bedford, MA, June 18, 2003--Schneeberger, Inc.-Schneeberger Inc. announced two new quality options for their cross-roller precision linear bearings-Option SQ and SSQ. Option SQ (Special Quality) is used in high demand applications such as optical measuring equipment and has a runout of no more than 5 microns over a travel distance up to 1800mm. Option SSQ (Super Special Quality) is used for the most stringent requirements, such as fiber optic splicing equipment and has a runout of no more than 2.5 microns over a travel distance of 1200mm.

Cross roller linear bearings offer extreme smoothness and virtually zero friction in a low-profile package. Compared to recirculating type linear bearings, cross roller guides have no pulsation effect caused by the rolling elements enterting and leaving the bearing load zone.

Schneeberger manufactures six types of linear bearings including the first standardized linear bearing in the world-Type R. The complete line up which includes cross roller bearings with a zero-cage-creepe assist option (Formula S) and needle bearings, consists of Type R, RN, RNG, RD, N/O, and M/V. A variety of ball and roller cages is offered by Schneeberger, including lightweight plastic, brass, and steel.

Schneeberger Inc., one of four subsidiaries of W. Schneeberger AG, headquartered in Switzerland, markets precision linear motion components and systems for demanding applications. Products include ball and cross-roller bearings, miniature slides and rails, profile guides, automated linear and rotary modules, multi-axis positioning systems, and precision ball screws. Based in Bedford, MA, Schneeberger, Inc sells directly through regional sales offices located throughout the US. For more information, contact Schneeberger at 1-800-854-6333 or visit
