Inch Linear Bearings and Metric Linear Bearings

Excel Linear Bearings

EXCEL™ Linear Bearings are designed to fit into precision bores while providing long life. Precision hardened and ground bearing plates with ball conforming tracks are contained in a molded thermoplastic housing.

LBB Linear Bearings

LBB Linear Bearings are used in lower load applications where self alignment is not required. The precision fit between the bearing and shaft is built into the bearing a result of the solid steel shell. A molded plastic bearing ball retainer is assembled inside a hardened and ground shell.

Pillow Blocks

EXCEL™ Linear Pillow Blocks Simply the mounting of Nook Linear Bearings. Available with EXCEL™ Bearings to fit shafts from 1/4 to 2 inch and 10 to 50mm. Provides the precision bearing bores necessary for linear bearing installation.

  • Manufactured from precision machined, thick walled, extruded aluminum.
  • Supplied with lip seals to keep out dirt and debris resulting in smoother operation and longer life.
  • Mounting surface to center line dimension is held to +/- 0.001 inch. Bearings will self-align up to +/- 0.5°.
