Linear Motion Assemblies and Sets

Crossed roller linear rail sets are compact, precision bearings that can support and guide high loads with high accuracy and repeatability, low friction, and low starting force. A complete range of sizes is supplied for use in precision machine tools, measuring instruments and anywhere reciprocating motion with high reliability and long life is required. Each bearing consists of a pair of hardened steel ways containing 90 V grooves and a row of alternately crossed cylindrical rollers. The hardened steel rollers are captive in a stainless steel cage for easy handling, assembly and permanent alignment. The ways are installed face to face on smooth flat and accurately parallel, coplanar, or perpendicular surfaces. Lubrication required depends on the application ranging from light grease for low speeds less than 50 inches per minute to continuous oil bath or mist at 1,200 inches per minute. Temperature of bearings must not exceed 212 F even for short periods as this will reduce hardness and performance. All are steel. Each set consists of two complete bearings (4 way bars, 2 roller cages, and end stops). Stainless steel and other sizes available as special order. Please call for price and delivery.

Crossed roller slide tables are factory assembled and ready to install. They use crossed roller bearings to provide very precise linear motion with low friction and high support stiffness for the load. A large selection is available for applications including precision instruments, office and communications equipment, surface grinders, tool grinders, assembly fixtures, and anywhere precise linear positioning is required. Precision ground V grooved ways and rollers provide high accuracy and load capacity. Withstands force in any direction from alternately crossed rollers at 45 angle. Standard pattern for easy installation and interchangeability with other manufacturers slides. Straight line accuracy .0001" inch. Each table consists of a one piece base, a one piece carriage and a pair of linear bearings. Steel type has cold rolled base and carriage with black oxide finish. Ends of carriage contain tapped holes that permit easy attachment of way covers, bellows or other shields to exclude dust and keep the ways clean. Aluminum is available for situations where particulate contamination must be reduced. Aluminum crossed roller slide tables have a gold anodized carriage and black anodized base. Other sizes and stainless steel bearings available as special order. Please call for price and delivery.
