The SEALMASTER USI5000 series insert bearing is a spherical roller bearing with an extended inner ring, made to seat in split plummer block housings and in wall or pillow block units. Its spherical outer raceway lets the insert align itself inside the housing, which suits applications where the shaft and housing are not perfectly aligned and loads come from more than one direction.

The code begins with USI, indicating a spherical roller insert with extended inner ring, followed by 5000 for the series. The number after the hyphen identifies the shaft size: USI5000-102, USI5000-103, USI5000-104, USI5000-107, USI5000-108, USI5000-111, USI5000-112 and USI5000-115 are examples. Because each suffix corresponds to a different shaft diameter, the complete part number is what you need when requesting a replacement.

These inserts are found in belt conveyors, bucket elevators, mixers, mills, screens and other process equipment where the shaft bends and alignment with the housing is not exact. They are common in food, cement and ceramic plants, aggregate processing and packaging lines, particularly in areas with dust, moisture or frequent washdowns. Machines that receive impacts or vibration also use them so the bearing absorbs misalignment instead of passing it to the shaft.

Selection starts with the shaft diameter and the housing type, confirming that the spherical outer raceway matches the housing seat. Review the seal: in dusty or wet conditions, choose a seal that keeps grease in and contaminants out. During mounting, keep the seat and shaft clean, avoid impacts on the outer raceway and lubricate before start-up. Check initial alignment and clearance, since excessive misalignment reduces insert life even when the bearing is self-aligning.

Spherical roller inserts from different brands interchange by shaft number, locking type and housing geometry, not by the commercial part number. If the equipment carries an insert from another brand, compare shaft diameter, inner ring width, locking system and outer raceway shape before replacing it. If the original part number is not available, send the shaft dimensions and a photo of the housing; we will identify the compatible alternative within the SEALMASTER line or the equivalent option that fits best.

When you need a USI5000 insert for equipment that is down, contact us on WhatsApp with the full part number or with the shaft dimensions and housing type. We will quote the reference and, if necessary, suggest a compatible alternative to get the machine running again. We also supply housings, seals and lubricants so the mounting can be completed in one inquiry.
