SN532 Bearings Boost Reliability in Heavyduty Industrial Use

In industrial machinery design, the selection of bearing housings directly impacts equipment stability, load capacity, and overall service life. Particularly for critical equipment subjected to high radial loads requiring precise alignment, split-type bearing housings have become indispensable solutions due to their unique structural advantages. Among these, the SN532 split bearing housing stands out as a flagship model in the SN series, playing a vital role in heavy-duty mechanical transmission systems through its robust construction, refined design, and broad application range.

SN532 Split Bearing Housing: The Foundation of Superior Performance

The SN532 split bearing housing belongs to the SN series of two-piece pillow block housings, specifically designed to accommodate spherical roller bearings and self-aligning ball bearings. It can be mounted on shafts either through adapter sleeves or direct interference fits. Its core design philosophy centers on providing a sturdy, reliable support structure capable of withstand demanding industrial environments and high-load applications.

Critical Dimensions and Specifications (SN532 Example)

• Shaft Diameter (di): 140 mm
• Outer Diameter (D, H8): 290 mm
• Total Length (a): 550 mm
• Width (b): 160 mm
• Height (c): 60 mm
