Linear Bearings and Pillow Blocks

PowerTrax™ and EXCEL™ Linear Bearings and Pillow Blocks

Nook Industries manufactures a full range of linear components. The PowerTrax™ line of linear components includes solid shell LBB linear bearings, self-aligning EXCEL™ linear bearings.

Open Series Bearings

For applications requiring fully supported shafts, "open" bearings are available in both LBB and EXCEL™ types. In an open bearing, one ball circuit is removed to allow the mounted bearing to translate along a supported shaft.


LBB and EXCEL™ bearings are available in sealed and unsealed versions. ILBB bearings are unsealed.


Nook PowerTrax™ linear bearings use a combination of high performance thermoplastic, chrome-steel bearing balls, and either a one piece hardened steel shell or precision ground hardened steel bearing plates.

Excel Bearing, Inch, High Load Self-Aligning

Self-Aligning Linear Bearing

EXCEL LINEAR BEARINGS Designed to fit into precision bores, these bearings are self aligning and offer long life. Precision hardened and ground bearing plates with ball conforming tracks are contained in a molded thermoplastic housing.

Excel Pillow Block, Inch

Pillow Block with Self-Aligning Linear Bearing

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

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

LBB Bearing, Inch, Non-Self-Aligning, Steel Shell

Non-Self_Aligning Linear Bearing

LBB These 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. These bearings utilize a molded plastic bearing ball retainer assembled inside a hardened and ground shell.
