SN Series Plummer Block Housings (SN 500 & SN 600 Series) | Split Cast Iron Bearing Housings
The SN Series Split Plummer Block Housings (ISO/R 113 & DIN 736/737 compliant) are heavy-duty, two-piece cast iron bearing housings engineered to deliver maximum rigidity and alignment stability under heavy operational loads. Designed primarily to accommodate self-aligning ball bearings and spherical roller bearings with adapter sleeves, SN housings simplify installation, lubrication, and routine maintenance across industrial setups.
Manufactured from high-grade Grey Cast Iron (GG20 / FG 200), these split housings feature precision-machined bearing seats to tolerance H7/H8. Each housing unit consists of a removable top cap and base, enabling smooth shaft assembly, inspection, and replacement without dismantling adjacent power transmission components.
