The SKF YAJ series covers insert bearings that lock onto the shaft with set screws. They are mounted on shafts and installed in split or pillow block housings. Equipment that needs a straightforward, sturdy bearing unit that is easy to replace is where these units are typically found. Their design handles minor misalignment and takes moderate radial and axial loads. Power transmission in industrial and agricultural settings is a common application area.
Reading a YAJ code helps when ordering a replacement. The series itself identifies an insert bearing with screw locking. A suffix such as F points to a particular locking groove or feature, while R followed by a number marks an outer diameter or dimensional variant. Take the code YAJ 218-2F/R899: size 218, variant 2F and reference R899 are combined. Understanding these suffixes is what makes it possible to order the right part.
Conveyor belts, grain elevators, mills, mixers and food machinery are typical hosts for these bearings. Seeders, harvesters and processing plants in the agricultural sector also use them. Their capacity to carry loads in both directions suits rotating shafts running at moderate speeds.
Selection starts with shaft diameter, load type and the surrounding environment. Set screw locking calls for a firm shaft fit and the correct tightening torque. Housing alignment must be checked, and lubrication should match the operating conditions. The 2F seal offers protection against dust and moisture; in a very aggressive setting, additional seals or bearings with stronger barriers are worth considering.
For equivalences, SKF YAJ insert bearings can be exchanged with other brands that share the same locking configuration and dimensions. Bore, outer diameter and width need to be confirmed, along with the locking and sealing type. Suffixes are not always equivalent between manufacturers, so actual measurements matter. MR Industrial Accessories supplies SKF as a brand and can advise on interchangeability.

Frequently asked questions
- What does the 2F suffix mean on a YAJ bearing?
- The 2F suffix denotes a specific sealing or protection variant. In the YAJ series, suffixes like this define features such as the seal type or the locking groove. Checking the complete designation with a specialist is the best way to know exactly what it means in your code.
- How is a Y-bearing with screw locking mounted?
- It goes onto the shaft and is secured with set screws that lock the inner ring. Cleaning the shaft well, verifying alignment and applying the recommended tightening torque are key. Correct lubrication and sealing help extend service life.
- Can I replace an SKF YAJ with another brand?
- Yes, provided the main dimensions and the locking type match. Do not rely on the code alone; compare bore, outer diameter, width and sealing system. MR Industrial Accessories can help you find the right equivalent.
