The SKF Y-bearing housing with insert bearing is a mounting unit that combines a cast iron or stamped steel housing with an insert ball bearing, already lubricated and sealed. It is used to support rotating shafts in transmission and conveying equipment, where a compact solution with self-alignment is required. MR Accesorios Industriales supplies this SKF line, a brand that MR carries, with alternatives for different shaft sizes and locking configurations.

The designation TUL identifies the Y-bearing housings of the series with insert bearing, and the suffixes TR and VE indicate sealing and locking variants. For example, TUL 20 TR/VE495 combines the base code with a suffix that defines the type of seal and the locking system of the insert on the shaft. Knowing these suffixes is key to ordering the correct replacement: the shaft diameter alone is not enough, because the same size can come with different protections and adjustment methods.

These housings appear in belt conveyors, bucket elevators, mixers, fans and packaging lines. In the Argentine industrial environment they are found in food plants, cement plants, tanneries and grain depots, where an environment loaded with dust or humidity demands reliable sealing. They are also used in irrigation equipment and agricultural machinery, since the housing allows mounting the shaft on sheet metal structures without additional machining.

To choose well, verify the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The TR seal usually offers greater protection against dust and water than a standard seal, while the suffix VE may indicate a variant with set screw or eccentric locking. During mounting, make sure the shaft is clean and free of burrs, and that the housing sits flat on the structure to avoid deformation.

The lubrication of the insert bearing is factory-filled, but it is advisable to check the condition of the seal and the presence of leaks before starting the equipment. Alignment between housings is essential: slight misalignment can generate parasitic loads and shorten service life. If the housing works in an environment with vibrations, consider additional fastening of the housing to the base to prevent it from loosening over time.

Regarding interchangeability, Y-bearing housings with insert bearing from different brands usually share standardized dimensions, but the sealing and locking suffixes are not always equivalent. Therefore, before replacing an SKF with another brand, compare the complete part number and the service conditions. If you have doubts, send the part number engraved on the housing via WhatsApp to MR Accesorios Industriales and we will help you identify the appropriate option.
