Our Linear Bearing Blocks are available with or without a flange and in standard or low profile height. All of the linear bearing blocks use a universal profile guide rail and both sides of the guide rail are ground as datum references.

Linear Bearing Blocks

RBS’ unique profile guide rail design allows both Standard Profile (RPGH) and Low-Profile (RPGS) series of linear bearing blocks to be installed on a common profile linear guide rail. They also have datum location reference surfaces ground on both sides, which permit universal mounting of linear guidance systems. .

Both the RPGH and RPGS blocks have four circular arc raceways; each raceway has a 45º contact angle which allows for equal loading in all directions. The raceways and Double Face Configuration (also known as an "X" Configuration) offers high-rigidity and tolerates misalignments of the rail. The RPG Linear Guide Series can be interchanged with most competitors' products.
