For maintenance and purchasing teams, the SKF PER.RRY series Y-bearing is an insert with a spherical outer ring that fits into split or pillow block housings. Set screws secure it to the shaft, and the design allows for slight misalignment. It suits transmission and conveying equipment that requires a sealed bearing which is easy to mount and resistant to contamination. MR Industrial Accessories supplies this line as one of its brands.

The part number breaks down into sections. The first letters indicate the Y-bearing category with a spherical outer ring. The number after PER. gives the insert size; for instance, PER.203RRY61 and PER.5204RRY2 have different shaft diameters. The RRY suffix shows the sealing type: contact seals that block dust and moisture. The final digits, such as 61 or 2, identify design or tolerance variants. Always select by the complete part number, not just the main number.

These bearings are found where a shaft rotates inside a housing and some misalignment tolerance is needed. Typical uses include conveyor belts in grain facilities, grain elevators, mixers, industrial fans, food machinery and packaging lines. They also appear in irrigation equipment, mills and aggregate conveyors. As sealed inserts, they handle dusty or moderately moist environments when mounted in proper housings and lubrication is monitored.

When choosing a Y-bearing, consider shaft diameter, housing type and operating conditions. The RRY contact seal needs a shaft surface in good condition to avoid seal damage. During mounting, check housing alignment and tighten set screws to the recommended torque. Factory grease often lasts several seasons, but in demanding settings it is wise to inspect and renew it. Do not strike the insert during installation, as this can harm seals or raceways.

Y-bearings from different brands can be interchanged if main dimensions, locking method and sealing match. The SKF PER.RRY series may be replaced by inserts with the same shaft diameter and screw configuration, but tolerances and load capacity must be checked. Matching the shaft number alone is not enough: the spherical outer ring and sealing system must also fit the existing housing. Consult a specialist if unsure before replacing.
