The SKF Y-bearing housing with insert bearing is an assembled unit that combines a housing unit with an insert bearing of the TUWK series. It is used to support rotating shafts in equipment where simple mounting and self-alignment are needed. It is a common solution in low and medium demand machines, and in applications where the shaft is not hardened or ground. MR Accesorios Industriales carries this SKF line.

The TUWK designation reads as a category of Y-bearing housings with insert bearing. The letters TU identify the type of unit, the W indicates that the housing is cast iron with a foot or flange shape depending on the case, and the K indicates that the insert bearing has a metric bore diameter. The number that follows, as in TUWK 506 L or TUWK 507 L, codes the size of the bearing and the housing. The final L suffix indicates a sealing or insert locking variant. To choose the correct part number, you have to cross the shaft diameter with the insert bearing series.

These housings are used in belt conveyors, packaging lines, mixers, fans, centrifugal pumps and light transmission lines. In Argentina they appear a lot in food plants, meat processing plants, tanneries and metalworking shops, where maintenance is done with the equipment stopped for the shortest possible time. They are also seen in agricultural machinery and in aggregate processing equipment. The advantage of the assembly is that the insert bearing already comes mounted in the housing, which reduces assembly time and avoids the error of mounting a loose unit.

To select well, first look at the shaft diameter and the type of load: radial, axial or combined. Then look at the insert sealing, because in environments with dust, water or chips a more robust closure is advisable. The internal clearance of the insert bearing is defined at the factory and is not adjusted during mounting. Lubrication is permanent in most cases, but in severe applications it can be relubricated if the insert has a channel. The alignment of the housing with the shaft is key: if the housing is crooked, the insert works forced and fails earlier.

As for equivalents, Y-bearing housings with insert bearing are available from several brands with similar part numbers, but they are not always interchangeable part by part. The main dimensions, such as shaft diameter and distance between holes, usually match between manufacturers, although the seals, housing materials and insert locking type change. Therefore, before replacing one unit with another, it is advisable to verify the full part number and the critical dimensions. If you have doubts, send us the code engraved on the old housing.
