SNL 3148
Split plummer (pillow) block housing, SNL 30, 31 and 32 series
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. Different housing variants and seal designs are available, making the use of tailored housings virtually unnecessary and enabling cost-effective bearing arrangements to be made.
- Easy to install
- Cost-effective bearing arrangement
- Reduce maintenance
- Minimize lubricant leakage
