The ERPB series of expansion roller bearing pillow blocks is designed for use in conjunction with the RPB and RPBA series where a “floating” or expansion type
block is required.
While two fixed units mounted on one shaft are normally satisfactory for most applications, expansion units are recommended:
1. Where bearing supports are not rigid.
2. Where significant temperature differentials are expected between shafts and mounting structures.
3. Where shaft is unusually long.
At least one bearing on each shaft must be of the fixed type.
Felt Seal Standard
Positive sealing for low, medium, and high
speed operation.
Single Lip Contact Seal
Available on all sizes. Recommended where
moisture conditions prevail.
For Replacement Cartridge Insert See Page 120.
For Load Ratings See Page 121.
For Metric Bores, See Page 127.
(1) Hi-Temp Units are factory assembled-to-order basis.
Hi-Temp Seal
Available as an option where operating
temperatures are in 250-400° range.
