A SEALMASTER PVR unit combines a two-bolt flange housing with a Y-bearing insert, letting you support a rotating shaft on a flat plate or frame and align it without a long installation. The design also absorbs small amounts of misalignment, which helps in equipment where the shaft and the mounting surface are not perfectly parallel. MR Industrial Accessories LLC supplies this line and helps buyers match the correct reference to their application.

Reading the code is the fastest way to identify a replacement. PVR marks the two-bolt flange housing family, and the digits that follow describe the housing and insert combination. Examples include PVR-1605, PVR-1608, PVR-1612, PVR-1615, PVR-1624, PVR-1626, PVR-3647 and PVR-3648. Because each suffix covers a different shaft size and bolt hole spacing, the complete number stamped on the part or printed on the drawing is what you need when ordering.

You will see these units on conveyors, belt systems, elevators, mixers, blowers and process lines in food, chemical, cement and aggregate plants. They suit dusty, damp or washdown areas, where a compact bearing that bolts to a plate and can be swapped out without tearing down the surrounding assembly is an advantage.

Selection comes down to three points: shaft diameter, distance between the flange holes and the sealing arrangement the environment calls for. Inserts commonly use set screws or an eccentric locking collar. Before mounting, confirm the shaft is clean and free of burrs and that the flange contacts the surface evenly. Correct lubrication and a fit made without hammering help the bearing run quietly and avoid vibration.

Two-bolt flange housings from different manufacturers can be exchanged when the shaft diameter and mounting dimensions line up, though seals, internal clearance and locking style may differ. No single cross-reference table covers every case, so comparing drawings is the reliable method. If you are moving away from a SEALMASTER unit, we can point you to an alternative that shares the critical dimensions.
