The SKF PER.HRRB series covers Y-bearings built as inserts, with an inner ring that extends beyond the bearing and set screws for locking onto the shaft. They seat in split housings or pillow blocks and suit equipment where the shaft turns and needs support plus protection from dirt and moisture. MR Industrial Accessories LLC supplies this line to plants and workshops across the United States and in several Latin American countries.

Reading the code helps you order the right piece. The number after PER. reflects the shaft size, and the trailing digits identify the construction version. So PER.205HRRB2 fits a 25 mm shaft, while PER.207HRRB12 and PER.207HRRB58 share a shaft diameter but are not the same variant. Because those final figures point to differences in outer ring design or sealing, a replacement request needs the full part number, not just the bore size.

You will find these inserts in belt conveyors, bucket elevators, mixers, mills, packaging lines and process equipment in food, chemical and aggregate operations. Sites that deal with dust, humidity or washdown depend on the seal to keep grease in and contaminants out. The extended inner ring also lets the bearing mount on shafts that have not been machined, and the set screws simplify maintenance work in the field.

Selection comes down to three checks: shaft diameter, housing type and the conditions around the bearing. The HRRB sealing arrangement is made to hold lubricant and resist ingress; where water or fine dust is present, review the sealing variant carefully. Clearance and lubrication should follow the manufacturer's instructions for the specific application. When mounting, line up the housing, then tighten the set screws onto the shaft with a proper wrench and avoid hammering the outer ring.

Interchange between brands is possible when the key dimensions line up: shaft diameter, outside diameter, width and locking method. Sealing suffixes and tolerances can differ, though, so a part number from another maker will not always drop in for the original. Our team can review equivalences and suggest alternatives within the SKF line we carry.

If the part number is stamped on the bearing or housing, send it to us by WhatsApp or email and we will quote that exact item. If you only have shaft and housing dimensions, we can help identify the series. MR Industrial Accessories LLC supports industrial maintenance and purchasing teams with power transmission components.
