Overview
The SKF SNL 507-606 VU split plummer block housing is a cast iron housing suitable for self-aligning ball bearings, spherical roller bearings, and CARB toroidal roller bearings with shaft diameter range 20 to 160 mm (3/4″ to 5.5″). SNL plummer block housings are the most popular SKF bearing housings on the market, developed to be the first choice for design, quality and economy. This split-design housing allows field installation without full shaft removal, reducing maintenance downtime on production equipment.
Key Features
- Split housing design — enables bearing installation and seal replacement without removing the shaft or dismounting connected equipment
- Cast iron construction — grey cast iron EN-GJL-HB235 in accordance with EN 1561 delivers durability and cost-effectiveness
- Two-bolt mounting — versatile seal designs including V-Ring (TSN-A), Felt (TSN-C), Four Lip (TSN-L), and Labyrinth (TSN-S)
- Low-maintenance operation — enables incorporated bearings to achieve maximum service life with less need for maintenance
- V-Ring seal variant — the VU designation indicates V-Ring elastomer seal for enhanced contamination exclusion

Typical Applications
SNL plummer block housings are used in machinery applications including conveyors, centrifuges, fans, motors, compressors, and general industrial rotating equipment. Different housing variants and seal designs are available, making the use of tailored housings virtually unnecessary and enabling cost-effective bearing arrangements. The split design is particularly valuable in retrofit installations and maintenance situations where the driven shaft cannot be easily removed.
