The SKF FYJ KF Y-bearing housed unit arrives preassembled, pairing a cast iron housing with a Y-series insert bearing. It supports rotating shafts in conveying, transmission and process equipment, and its bolt-on design simplifies alignment and mounting. This makes it a practical choice for moderate loads and medium speeds.
Reading the code helps you order correctly. FYJ denotes the SKF cast iron housing series for bolt mounting. The number that follows is the shaft diameter in millimeters, so FYJ 30 KF fits a 30 mm shaft. The KF suffix points to an insert bearing held by set screws with standard sealing. Common sizes include FYJ 40 KF, FYJ 45 KF, FYJ 55 KF and FYJ 65 KF.
Typical installations include conveyors, elevators, mixers, fans, pumps and agricultural machinery. The cast iron housing withstands dusty and damp conditions, and because the insert bearing is a separate element, it can be replaced without pulling the shaft apart. MR Industrial Accessories LLC supplies this line to customers throughout the United States and in several Latin American countries.
Selection comes down to shaft diameter and load type. The insert seal keeps contaminants out; for wet or dusty areas, look at versions with extra sealing. Factory grease usually covers normal duty, though harsh conditions may call for relubrication. When mounting, make sure the base sits flat and tighten the insert set screws to the recommended torque. Proper alignment avoids added stress and supports service life.
Y-bearing housed units can be swapped between brands when the key dimensions line up: shaft diameter, center height and mounting hole spacing. SKF is one of the brands we supply, and the FYJ KF series is part of that range, but equivalents exist. Always confirm the standardized dimensions before replacing. If anything is unclear, send us the original part number.

Frequently asked questions
- What does the KF suffix mean in the FYJ housing?
- KF identifies a housing variant whose insert bearing is secured by set screws and uses standard sealing. Check the full part number to confirm it matches your shaft and application.
- Does this housing come with the insert bearing included?
- Yes. The FYJ KF Y-bearing housed unit is supplied assembled, with the housing and insert bearing together. That simplifies mounting and reduces the chance of selecting the wrong components.
- How do I know if the housing is compatible with my machine?
- Compare the shaft diameter, the center height and the distance between the mounting holes. If those match your equipment, the housing is interchangeable. If in doubt, consult us with the original part number.
