The SKF PER.W RRRB-A Y-bearing is an insert bearing designed for use in pillow block and flange housings. It features a spherical outer ring that accommodates minor misalignment and a set screw locking system for quick shaft mounting. The double-lip seal provides reliable protection in dusty or wet conditions, making it suitable for conveyors, fans, and processing equipment.
The part number structure helps identify key features. The prefix PER indicates the series, while W denotes a specific design variant. RRRB refers to the seal type—two rubber lips that keep out contaminants. The suffix A signals an internal modification, often related to clearance or cage. For example, PER.W5207RRRB60-A includes the size code 5207 and the additional identifier 60. Always use the complete code stamped on the bearing when ordering a replacement.
These bearings are common in power transmission systems such as belt conveyors, bucket elevators, mixers, and fans. They also suit food and beverage machinery, agricultural equipment, and other applications where dust or moisture is present. The set screw locking allows installation without a press, and the spherical outer ring compensates for shaft misalignment, reducing stress on the seal and rolling elements.
To select the right bearing, confirm the shaft diameter, housing type, and operating environment. The RRRB seal is ideal for dirty conditions; for frequent washdowns, consider additional sealing options. During installation, clean the shaft and tighten the set screws to the recommended torque—over-tightening can distort the inner ring. Factory grease typically lasts the bearing's service life, but severe applications may require relubrication. Proper housing alignment is essential to avoid premature seal wear.
When comparing equivalents across brands, match not only the shaft diameter but also the inner ring width, set screw location, and seal design. These dimensions vary between manufacturers and affect fit and performance. If you are unsure, send the complete part number to MR for assistance in identifying a compatible reference.
