The SKF YAR ...RF/W... is an insert bearing with an extended inner ring and set screw locking, made to fit into split or pillow block housings. It suits equipment with rotating shafts that needs a straightforward, easy-to-service bearing unit. The 2RF seal keeps contaminants out, while the W64 suffix points to a special variant for particular operating conditions.
Reading the code: YAR is the insert series with an extended inner ring and two set screws for shaft locking. The number in the middle, such as 208 or 209, ties to the shaft diameter. The 2RF suffix describes the seal: a double rubber lip with metal reinforcement that holds grease in and blocks contaminants. W64 marks a special-treatment variant, which may relate to high temperatures or specific conditions. Examples YAR 208-2RF/W64 and YAR 209-2RF/W64 follow this pattern.
These bearings appear in many industrial settings: conveyors, mixers, fans, pumps, mills, belt systems and agricultural machinery. They are common in food, cement, mining and aggregate processing plants where dust or moisture is present. Because they mount in split or pillow block housings, replacement and alignment are simpler.
When choosing a Y-bearing, look at shaft diameter, radial and axial loads, and the environment. The 2RF seal works well with moderate dust or humidity; for liquid exposure, consider extra sealing. Factory lubrication is typically lithium grease, but check compatibility before relubricating. At mounting, keep the shaft clean and free of burrs, and tighten the set screws with a torque wrench to the recommended value. Housing alignment matters to avoid extra loads.
For equivalences, SKF Y-bearings can be swapped with other brands that share the same dimensional standard. The YAR designation is SKF-specific, but other makers use similar codes for inserts with an extended ring and screw locking. Always confirm the critical dimensions: shaft diameter, total width, outer diameter and seal type.

Frequently asked questions
- What does the 2RF suffix mean on a YAR bearing?
- The 2RF suffix indicates a double rubber seal with metal reinforcement, which protects against dust and humidity. It is important for contaminated environments.
- What is the W64 variant used for?
- W64 is an SKF designation for a special variant, generally associated with heat treatments or high-temperature lubricants. Consult us for the specific application.
- How is a Y-bearing mounted on the shaft?
- It is mounted with the extended inner ring on the shaft and locked with two set screws. It is key to clean the shaft and tighten the screws to the correct torque to prevent slipping.
