SN214 Plummer Block Bearing Housing
Product Overview
The SN214 Plummer Block Bearing Housing (Split Pillow Block) is designed as a heavy-duty, reliable, and versatile housing solution for spherical roller bearings, self-aligning ball bearings, and barrel roller bearings. Manufactured from high-grade cast iron, the split-body design allows for easy assembly, inspection, and maintenance of pre-assembled shafts.
Whether your customers are looking for fixed or floating bearing arrangements, the SN214 offers optimal sealing protection and robust load distribution to prolong bearing service life in harsh environments.
Industrial Applications
The SN214 housing is widely integrated into power transmission systems and rotating machinery across various heavy industries. Key applications include:
Conveyor Systems & Bulk Material Handling: Ideal for drive pulleys and return pulleys in mining, quarrying, and cement plants.
Fans and Blowers: Used in heavy-duty industrial ventilation and air-handling units.
Agricultural Machinery: Fits large-scale processing equipment, grain elevators, and shredders.
Pulp & Paper Machinery: Applied in drying cylinders, felt rollers, and paper manufacturing lines.
Crushers and Shredders: Built to withstand high radial loads and vibration in recycling and stone crushing plants.
Water Treatment & Pumps: Supports large centrifugal pumps and water processing agitators.

Please Note:
Standard Dimensions: All sizes in this table conform to international standards and are 100% interchangeable with major global brands (SKF, FAG, NSK, etc.).
Theoretical vs. Actual Weight: Weights listed are theoretical net weights for the cast iron housing only (excluding bearings & packaging). Due to the casting process, actual weights may have a normal tolerance of $\pm$3% to $\pm$5%.
Fixed/Floating Arrangements: Quantities for locating rings (e.g., 2 pcs of SR125×10 for SN214) are for fixed-end configurations.
Shipping Weight: For bulk wholesale container loading and ocean freight calculation, full gross weights (including wooden pallets/crates) will be detailed in your official Packing List.
