The INA Y-bearing of the GVK-KTT-B series is an insert with an extended inner ring and a set screw locking system, designed to be mounted in split plummer block or flanged housings. It is used in equipment where the bearing must remain fixed to the shaft and allow rotation with simple alignment, such as conveyor belts, fans, mixers and process machinery. Its sealed construction makes it suitable for environments with dust, moderate humidity and permanent lubrication.

The GVK-KTT-B series designation is read in blocks: GVK identifies the family of inserts with an extended inner ring and set screw locking; the number that follows, as in GVK104-209-KTT-B or GVK109-211-KTT-B, encodes the shaft diameter and the size of the associated housing. The KTT suffix indicates the sealing type, with contact seals that protect the raceway, and the final B corresponds to a construction variant of the insert. That combination defines the mounting and the degree of protection, not a standalone measurement.

In Argentine industry, this type of Y-bearing appears in belt conveyors, bucket elevators, mixers, dryers and milling equipment. It is also found in machines for food processing, packaging and aggregate treatment, where the shaft rotates at moderate speeds and the load is mainly radial. As it is an insert, it is replaced with the housing already mounted on the machine, which simplifies maintenance in plants that work with scheduled shutdowns.

To select the insert, verify that the shaft diameter and the housing bore match the code. The KTT sealing requires checking that the lips are not damaged and that the environment does not exceed the working temperature of the seal. During mounting, tighten the set screws on the inner ring with the appropriate wrench, without overdoing it, and verify the alignment of the housing to avoid parasitic axial loads. Lubrication comes from the factory; in service, replenish grease according to the duty cycle.

Y-bearings are interchanged between manufacturers by equivalence of dimensions and locking type, not by the complete code. An insert with an extended ring and set screws can replace another of the same diameter and width, but the sealing and the shape of the outer ring must be checked. If the housing is from another brand, it is advisable to compare the outer diameter of the insert and the locking system before replacing. MR Accesorios Industriales sells INA and can guide you with the equivalence.
