SNL plummer (pillow) block housings in the 30, 31 and 32 series are robust and suitable for tough operating conditions.
They enable the incorporated bearings to achieve maximum service life with less need for maintenance. Oil seals are supplied together with the housing as a unit.
- Easy to install
- Cost-effective bearing arrangement
- Reduce maintenance
- Minimize lubricant leakage
