The INA Y-bearing (insert bearing) is a ball bearing with a spherical outer ring and a built-in locking unit, designed to be mounted in split plummer block or flanged housings. It is used in equipment where the shaft rotates and requires alignment and sealing. The SK KTT B series covers metric and inch sizes, with locking variants using set screws or an eccentric ring. MR Accesorios Industriales supplies this INA line in Buenos Aires, Argentina.

The SK KTT B series designation is read in blocks: SK identifies the series of insert bearings with a spherical outer ring; KTT indicates the sealing type, with contact lips that retain grease and block contaminants; B indicates the inner ring design, with a specific configuration for shaft locking. The suffixes that follow, as in the example SK104-208-KTT-B-L402/70-AH10, provide size and variant data: L402/70 defines a special sealing or tolerance execution, and AH10 refers to the locking system. Each block condenses key information for identifying the replacement part.

These insert bearings are used in conveyors, belts, elevators, mixers, bottling equipment and agricultural machinery. In Argentina they are common in food plants, meat processing plants, aggregate treatment plants and packaging lines, where a humid or dusty environment demands effective sealing. They are also found in industrial fans and process centrifugal pumps. Their ability to self-align within the housing absorbs small shaft misalignments and reduces corrective maintenance.

To select the correct Y-bearing, take into account the shaft diameter, the locking type (set screws or eccentric ring), the sealing required according to the environment, and the expected radial and axial load. Mounting must be done on a shaft with the proper tolerance, clean and free of burrs. Factory lubrication is usually sufficient for the service life, but in severe applications scheduled relubrication is advisable. Check the housing alignment and the tightening of the locking screws to prevent slipping.

Regarding equivalents, INA Y-bearings can be interchanged with those of other brands that follow the same dimensional standard. The key is to compare bore diameter, outside diameter, width and locking type. The part number alone is not enough: the sealing execution and the inner ring tolerance must be verified. If you have any doubts, send the complete part number or the dimensions of the original bearing by WhatsApp to MR Accesorios Industriales and we will quote you promptly.
