The SKF Y-bearing PER.203RRR5-A is a sealed insert with an extended inner ring and set screw locking, designed for mounting in split plummer block or pillow block housings. It handles radial loads and some axial thrust, making it suitable for conveyors, fans, and agricultural equipment. Its RRR5 seal provides protection against dust and moisture. MR Industrial Accessories supplies this brand and can help you select the right insert for your application.
The part number PER.203RRR5-A breaks down as follows: PER identifies a Y-bearing of the PER series with extended inner ring and set screw locking; 203 is the bore size code in the SKF numbering system; RRR5 denotes a double-lip seal with additional contaminant protection; and the final A indicates a design variant. Understanding these codes helps you order the exact replacement without confusion.
Typical applications include food processing, agriculture, and logistics. This bearing is often found in conveyor belts at grain storage facilities, screw conveyors, shed fans, combine harvesters, bottling lines, and package conveyors. Its ability to withstand radial loads and moderate axial thrust makes it versatile for shafts rotating at moderate speeds with simple maintenance requirements.
When selecting an insert, confirm that the shaft diameter matches the bearing bore and that the housing is compatible with the PER series. The RRR5 seal suits environments with moderate dust or moisture; for frequent washdown, consider additional protection. During mounting, tighten the set screws onto the shaft with the appropriate wrench and check housing alignment to avoid parasitic loads. Lubricate according to operating conditions and periodically inspect the seals.
Y-bearings from different brands can be interchanged if the main dimensions and locking type match. The SKF PER series has counterparts in other brands, but seal suffixes and tolerances may vary. Always compare bore diameter, overall width, and outer diameter before replacing. MR Industrial Accessories can help you find the right replacement.

Frequently asked questions
- What does the RRR5 suffix indicate?
- The RRR5 suffix specifies the seal type: a double-lip seal with extra protection against dust and moisture, intended for moderately contaminated industrial settings. It does not alter the bearing's main dimensions.
- Can this insert be used with housings from other brands?
- Yes, provided the housing bore dimensions and locking system match. The SKF PER series is generally interchangeable with other brands, but always verify bore diameter and outer ring width before mounting.
- How should I mount and lubricate this bearing?
- Mount the insert on the shaft, tighten the set screws with the correct wrench, and secure it in the housing. Lubricate with a quality grease suited to the operating conditions. Regularly check seal condition and alignment to prevent premature wear.
