For split housings and split bearing units, the SEALMASTER ERX-PN series insert bearing offers a spherical roller design with an extended inner ring. It compensates for shaft-to-housing misalignment and carries moderate radial and axial loads in equipment that runs continuously, which makes it a practical choice where mounting and removal need to be quick and repeatable.
Break the ERX-PN code into its parts and the number becomes easy to read. ERX marks the SEALMASTER insert family with extended inner ring and set screw locking, while PN identifies the version built for split housings. The digits that follow give the shaft diameter, so ERX-PN20R and ERX-PN32R are simply two sizes in the same line, and the closing R defines the sealing and locking arrangement for this series. When requesting a quote, copy the full part number from the component or the equipment plate.
Typical duty includes belt and roller conveyors, mixers, mills, bucket elevators, packaging lines and aggregate processing, as well as food, cement, mining and wastewater treatment operations. In all of these, the split housing lets maintenance crews service the bearing position without pulling the whole shaft. MR Industrial Accessories LLC supplies the SEALMASTER brand and serves customers throughout the United States and in several Latin American countries.
Selection starts with the shaft diameter, the housing it fits and the operating environment: dust, moisture, washdown or elevated temperature. Review the sealing arrangement, internal clearance and shaft locking method before installation. Use the lubricant called for by the rotation speed and the surrounding conditions, and keep the housings aligned within the range the self-aligning bearing can absorb. Striking the insert during mounting or leaving it misaligned will cut its service life.
Spherical roller inserts are matched across brands by shaft size and housing type rather than by the manufacturer's part number. An equivalent series may use different sealing, locking or tolerances, so compare the full designation and the main dimensions before substituting. Our team can point you to a compatible option.
Send the part number from the bearing or the equipment plate to our team by WhatsApp or email, along with a photo of the housing and shaft. With that information we will quote the SEALMASTER ERX-PN series insert or a suitable equivalent and reply promptly. If the variant you need is not listed, tell us the model and we will help you locate it.

Frequently asked questions
- What does the ERX-PN code tell me about this insert?
- ERX is the SEALMASTER insert line with extended inner ring and set screw locking, and PN is the version made for split housings. The following number is the shaft diameter, and the trailing R covers the sealing and locking setup.
- How can I replace it if the same part number is not available?
- Match the shaft diameter, housing type and locking method first. Send the part number and a photo by WhatsApp or email, and we will quote a compatible option from the same line or another brand.
- What should I watch during mounting and lubrication?
- Keep the shaft clean, align it with the housing and avoid impact during installation. Verify clearance and seals before start-up, and choose a lubricant suited to the speed and environment; in dusty or wet areas, inspect the seal more often.
