Plain Bearings Simplicity ®

Self-Alignment Feature Simplicity bearings are available with a standard straight O.D. or a crowned self-aligning O.D. FL – (Standard): • Straight O.D. • Standard pillow blocks have the self-aligning capability designed into the block using standard “FL” bearings for the final assembly FLA – (Self-aligning O.D.): • Has a crown on the O.D. allowing the bearing to re-align itself in binding situations • Specifically designed to easily retrofit straight bore housings • The bearing will allow 1/2° of misalignment capability from centerline (1° overall) • O-rings can be used on either side of the crown to cushion and eliminate clatter in operation (sold separately)

Standard FL – Straight O.D. Note: Standard pillow blocks use FL bearings with self-alignment built into the I.D. of the block.

Self-Aligning FLA – Spherical O.D. Note: Use in straight bore housings.

Pillow Blocks • Made of aluminum alloy • Pillow blocks are interchangeable with industry standard ball bearing pillow blocks • Critical centerline dimensions hold accuracy within ±0.001" on inch sizes and ±0.015 mm on metric sizes FINISHES:

• Clear anodized finish (Standard) Standard pillow blocks have built-in self-alignment in all directions: • Standard pillow blocks have 1/2° misalignment from centerline • This feature is built into the housing with a spherical radius at the midpoint of the block • This self-aligning capability will allow for some shaft deflection and misalignment Rigid or straight bore housings are available: • This does not allow for any self-alignment and provides a very rigid assembly • They are typically used in single shaft applications
