Sealmaster SPM-31-CXU Pillow Block Bearing 1-15/16 Bore

The Sealmaster SPM-31-CXU pillow block bearing is a fixed, two-bolt mounted ball bearing unit with a 1-15/16 in bore designed for medium-duty service. Housed in cast iron, the SPM-31 CXU accepts a 1-15/16 in shaft and is configured as a non-expansion (fixed) bearing suitable for continuous operation in industrial machinery. The unit features a 2-bolt base and bolt-center-to-bolt-center spacing of 6-3/4 in to 8-1/2 in, a base-to-bore centerline of 2-3/4 in, and overall dimensions of about 10-1/2 in long by 5-5/16 in high. As part of Sealmaster's SPM medium-duty family, this bearing provides rugged shaft support with a standard footprint for 1-15/16 in bore applications and fixed-geometry alignment, making it well suited for installations that require reliable, straightforward mounting and maintenance in machinery where a conventional pillow block arrangement is desired.
