EXCEL SELF-ALIGNING LINEAR PILLOW BLOCKS

MOUNTING TOLERANCES The PowerTrax™ Pillow Block mounting surface to centerline dimension is held to ±0.001 inch. Bearings will self-align up to ±1/2°.

MATERIALS All PowerTrax™ Pillow Blocks are manufactured from precision machined, thick walled, extruded Type 6061-T6 aluminum.

PILLOW BLOCK SEALS 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.

EXCEL FLANGE-MOUNT PILLOW BLOCKS
EXCEL™ Linear Bearings provide high efficiency and smooth operation in a variety of linear guidance applications. EXCEL™ Flange-Mount Pillow Blocks offer an installation alternative to standard foot-mount pillow blocks when the mounting surface is perpendicular to the guide shafts. Nook Industries flanged mount pillow blocks are available in both single and twin bearing styles and include 1/2 , 3/4 or 1 inch EXCEL™ Linear Bearings. The blocks have integral lip seals, an aluminum housing and a lubrication port. Typical applications include: platform guidance, end stop support, conveyor width adjust mechanisms, edge guides and machine operator guards.
