Linear Bearings and Pillow Blocks
PowerTrax™: 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.
- Mounting surface to center line dimension is held to ±0.001 inch. Bearings will self-align up to ±1/2°.
- Manufactured from precision machined, thick walled, extruded aluminum and are supplied complete with lip seals.
- The sealed pillow block keeps lubricant in and dirt and debris out resulting in smoother operation and longer bearing life.
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.
