SNL 520-617
Split plummer (pillow) block housing, SNL 2, 3, 5 and 6 series
SNL plummer (pillow) block housings are the most popular SKF bearing housings on the market, developed to be the first choice for design, quality and economy.
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
