The SKF Y-bearing YAJ series is an insert bearing with set screw locking, designed to be mounted on shafts and housed in split or pillow block housings. It is used in equipment that requires a simple, robust and easy-to-replace bearing unit. Its design compensates for minor misalignments and supports moderate radial and axial loads. It is a common solution in power transmission for industry and agriculture.

The YAJ series designation reads as a category of insert bearings with screw locking. The suffix F indicates that the bearing has a specific locking groove or feature, while R followed by a number refers to the outer diameter or a dimensional variant. For example, the code YAJ 218-2F/R899 combines size 218 with variant 2F and reference R899. Knowing these suffixes is key to ordering the correct replacement.

These bearings are used in transmission equipment such as conveyor belts, grain elevators, mills, mixers and food machinery. They are also found in the agro-industrial sector, in seeders and harvesters, and in processing plants. In Argentina, they are common in the oilseed, meatpacking and animal feed industries. Their ability to support loads in both directions makes them versatile for rotating shafts at moderate speeds.

To select a Y-bearing from this series, take into account the shaft diameter, the type of load and the environmental conditions. Set screw locking requires a firm fit on the shaft, with the proper tightening torque. It is important to verify housing alignment and lubricate correctly according to the operating conditions. The 2F seal protects against dust and moisture, but if the environment is very aggressive, it is advisable to evaluate additional seals or bearings with better barriers.

Regarding equivalences, SKF YAJ insert bearings can be interchanged with other brands that offer the same locking configuration and dimensions. Always verify the bore, outer diameter and width, as well as the locking and sealing type. Not all suffixes are equivalent between manufacturers, so it is essential to compare actual measurements.
