The PEER GR series is a line of insert bearings built with an extended inner ring, intended for installation into split or solid housings. Once mounted, they form a complete support unit that simplifies alignment and replacement in rotating equipment such as conveyors, fans, and mixers. MR Industrial Accessories LLC supplies these bearings to maintenance and purchasing teams across the US, Canada, Mexico, and South America.

Reading a GR part number is straightforward: the digits after the letters (204, 205, 206, etc.) order the series by increasing bore size. The suffix after the hyphen gives the exact bore in millimeters—for instance, GR204-20mm has a 20 mm bore, GR205-25mm has 25 mm, and the sequence continues up to GR211-55mm. This coding lets you quickly identify the insert that matches your shaft.

These inserts are common in belt conveyors, bucket elevators, dryers, industrial fans, and agricultural machinery. They perform well in dusty or humid environments where a robust support and easy maintenance matter. Because the insert can be replaced without removing the entire housing, they are also practical for older machines that are repaired frequently.

Selection starts with three checks: shaft diameter, housing type (split or solid), and the sealing required by the operating environment. The GR insert mounts on the shaft with set screws on the extended inner ring, and proper lubrication plus careful housing alignment will help extend service life. In dirty conditions, inspect the seal and internal clearance before installation.

When replacing an insert, always compare the complete part number and the three main dimensions: bore, outer diameter, and width. Cross-brand equivalents are determined by those dimensions and the locking method, not just the series number. If you have a part number from another brand or an unmarked part, send it to MR Industrial Accessories LLC and we will identify a compatible alternative.
