SN Series Plummer Block Housings (SN 500 & SN 600 Series) | Split Cast Iron Bearing Housings

Plummer blocks (split bearing housings) are designed to support heavy radial loads and self-aligning bearings in demanding industrial environments. They protect spherical roller bearings and self-aligning ball bearings from dust, moisture, and contaminants while maintaining precise shaft alignment under heavy operational vibration.

At Rajasthan Bearings, we stock a complete range of split Plummer Block housings (SN, SNH, SNA, and SD Series) as well as mounted unit housings (UCP, UCF, UCFL, UCT), manufactured in high-grade Grey Cast Iron (FG 200/250) and Ductile Iron for maximum fracture resistance.

We supply standard and customized plummer blocks for conveyors, crushers, paper mills, steel plants, and heavy machinery across West Bengal and eastern India.
