The SKF Y-bearing housing unit with insert bearing from the TUWK LTHR line is an assembled unit that combines a housing unit with a Y-series insert bearing. It is used to mount rotating shafts in fixed structures, providing support and allowing rotation with self-alignment. It is a practical solution for equipment where mounting and dismounting must be simple, and for applications with shafts from 20 to 40 mm in diameter.
The TUWK LTHR designation is read in parts. TUWK identifies the housing type: a Y-unit with housing and insert bearing, with a design that allows mounting on flat surfaces. LTHR indicates the sealing and lubrication variant: the insert comes with lip and groove seals that retain lubricant and block the entry of contaminants. The numbers appearing in the examples, such as 20, 25, 30, 35 and 40, correspond to the shaft diameter in millimeters for which each unit is intended. Thus, TUWK 20 LTHR mounts on a 20 mm shaft, TUWK 25 LTHR on a 25 mm one, and so on.
These housings are seen in belt conveyors, bucket elevators, machines for the food industry, packaging equipment and process lines in general. They also appear in fans, mixers and transmission systems where the shaft rotates at moderate speeds. In Argentina, you will find them in food, beverage, chemical, cement and aggregate processing plants, among others. Their compact format and the possibility of mounting them with screws make them suitable for folded sheet metal or cast structures.
To choose the correct housing, first check the shaft diameter and the type of load: radial, axial or combined. Check that the housing has the necessary rigidity and that the mounting surface is clean and flat. The insert usually comes pre-lubricated; during mounting, avoid striking the inner ring and use a tube or socket that rests on the inner ring. Alignment between housings is key so that the bearing works without lateral stresses. If the environment has dust, water or frequent washdowns, the LTHR sealing helps extend service life.
Regarding interchangeability, Y-bearing housing units with insert bearings from different brands often share standardized dimensions, but do not assume that a part number from another brand replaces the TUWK LTHR without verifying mounting dimensions, shaft diameter and type of fixing. The SKF TUWK series is a well-known reference, and there are equivalents from other manufacturers on the market. It is always advisable to compare drawings or samples before substituting. If you have doubts, send us the complete part number and the shaft dimensions.

Frequently Asked Questions
- What does the abbreviation TUWK LTHR mean in this SKF housing?
- TUWK identifies the Y-bearing housing unit with insert bearing. LTHR indicates the sealing and lubrication variant, with lip and groove seals that protect against contaminants. The numbers in the examples, such as 20 or 25, correspond to the shaft diameter in millimeters.
- How do I choose the right housing for my shaft?
- First measure the shaft diameter and define whether the load is radial, axial or combined. Check that the housing is rigid and the mounting surface is flat. If there is dust or water, prioritize a seal such as LTHR. If in doubt, consult us with the dimensions.
- Can I replace a housing from another brand with this SKF TUWK LTHR?
- In many cases yes, because mounting dimensions are often standardized. But do not rely only on the part number: compare shaft diameter, distance between holes and type of fixing. Send us the dimensions or the drawing and we will help you verify the equivalence.
