Description
SKF TUWK 25 LTHR belongs to y-bearing unit, part of our Bearing housings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for TUWK 25 LTHR and any equivalents.
The SKF TUWK LTHR is a pre-assembled unit that pairs a Y-bearing insert with a housing, designed to support rotating shafts in fixed structures while allowing self-alignment. It suits equipment where installation and removal need to be straightforward, and it covers shaft diameters from 20 to 40 mm.
Break the code into two parts. TUWK tells you it is a Y-unit with housing and insert, built for mounting on flat surfaces. LTHR describes the sealing and lubrication arrangement: the insert carries lip and groove seals that keep lubricant in and contaminants out. The numbers that follow—20, 25, 30, 35, 40—give the shaft diameter in millimeters. So TUWK 20 LTHR fits a 20 mm shaft, TUWK 25 LTHR a 25 mm shaft, and so on.
You will see these units on belt conveyors, bucket elevators, food-processing machines, packaging equipment and general process lines. They also turn up in fans, mixers and transmission systems running at moderate speeds. The compact footprint and screw mounting make them a good match for folded sheet metal or cast structures.
Selection starts with shaft diameter and load direction: radial, axial or combined. Confirm the housing has enough rigidity and that the mounting surface is clean and flat. The insert typically arrives pre-lubricated; during installation, avoid hammering the inner ring and use a tube or socket that presses on the inner ring. Aligning the housings matters so the bearing does not run with side stresses. In dusty, wet or washdown environments, the LTHR seal helps extend service life.
Interchangeability: Y-bearing housing units from various brands often share standardized dimensions, but never assume a part number from another brand directly replaces the TUWK LTHR without checking mounting dimensions, shaft diameter and fixing type. The SKF TUWK series is a common reference, and equivalents exist. Compare drawings or samples before substituting. If you are unsure, send the full part number and shaft dimensions.

Frequently asked questions
- What does TUWK LTHR mean on this SKF housing?
- TUWK identifies the Y-bearing housing unit with insert bearing. LTHR is the sealing and lubrication variant, with lip and groove seals that block contaminants. The number after TUWK, such as 20 or 25, is the shaft diameter in millimeters.
- How do I select the correct housing for my shaft?
- Measure the shaft diameter and determine whether the load is radial, axial or combined. Check that the housing is rigid and the mounting surface is flat. For dusty or wet conditions, choose a seal like LTHR. If you need help, contact us with the dimensions.
- Can I replace a housing from another brand with this SKF TUWK LTHR?
- Often yes, because mounting dimensions are frequently standardized. But do not rely on the part number alone: compare shaft diameter, hole spacing and fixing type. Send us the dimensions or drawing and we will help you verify the equivalence.
