Boston Gear SRP-20 Pillow Block Bearing One And One Quarter Bore

Boston Gear SRP-20 pillow block bearing is a light-duty, fixed (non-expansion) unit with a 1-1/4 in bore and a plain sleeve bearing, set inside a cast-iron pillow block that mounts to a 2-bolt base. This configuration provides straightforward shaft support and alignment for machinery that requires a reliable, low-maintenance bearing block in compact installations. The SRP series employs a durable cast-iron housing and a simple plain-sleeve insert designed to accommodate standard shaft sizes while resisting distortion under ordinary operating conditions. With its 2-bolt base, the unit installs quickly to a flat surface, helping maintain shaft concentricity and tension in the drive path. The fixed bore of the SRP-20 ensures consistent alignment of the rotating shaft, making it a practical choice for light industrial equipment where a rugged, economical pillow block is desired and serviceable by standard bearing specialist parts.
