The SEALMASTER PVR series is a cartridge-style Y-bearing housed unit. It pairs a cartridge-shaped outer ring with an insert that locks to the shaft using set screws. The unit mounts into a machined bore or box, making it a practical choice when a rotating shaft needs compact, self-aligning support without a bolt-on housing.

The PVR code follows a simple pattern: the letters indicate the cartridge family, and the numeric suffix identifies the size and variant. Examples include PVR-1102, PVR-1106, PVR-1113, PVR-1121, PVR-1127, PVR-1128, PVR-1720 and PVR-2137. The number changes with shaft diameter and insert configuration, so the full code is essential for correct identification.

These cartridges are common in belt and roller conveyors, bucket elevators, mixers, screens, packaging lines and process equipment. They also appear in agricultural machinery, food and beverage plants, and assemblies where the shaft carries moderate radial load and some misalignment. Because the unit is self-aligning, it accommodates small alignment errors between shaft and housing, which is typical in vibrating equipment or on-site assembly.

When selecting a cartridge, consider shaft diameter, insert fixing type (set screws or eccentric), sealing and internal clearance. The seal determines how much contamination the unit can tolerate; dusty or wet environments call for tighter protection. During mounting, the housing bore must be clean and free of burrs, the shaft should show no wear in the support area, and the lubricant must suit the working temperature. Careful alignment helps extend bearing life.

SEALMASTER is a brand that MR supplies, and its cartridge units can interchange with those from other mounted bearing brands when shaft diameter, insert type and housing dimensions match. Interchangeability is not just about the code: cartridge geometry, fixing system and sealing must be compared. Send us the original unit's code and we will identify the compatible alternative from the lines we carry.

To replace a PVR cartridge or specify one for new equipment, send the full code, shaft diameter and a photo of the housing via WhatsApp or email.
