The SKF TUL 25 TH is a ready-to-mount assembly that pairs a housing with an insert ball bearing. It supports rotating shafts where simple installation and slight misalignment compensation are needed. MR Industrial Accessories supplies this SKF line and offers technical guidance to match the unit to your shaft diameter and locking method.
The code TUL 25 TH follows a pattern: TUL indicates the housing style and insert locking system, 25 stands for the shaft diameter in millimeters, and TH denotes a sealing or insert variant. This structure repeats across the series, as seen with TUL 30 TH and TUL 35 TH, where only the middle number changes to match different shaft sizes.
Typical applications include belt conveyors, packaging equipment, mixers, fans, centrifugal pumps, and light-duty transmission lines. They are also common in irrigation systems and continuously operating agricultural machinery, where easy replacement and tolerance to minor misalignment are more important than the precision of a fixed bearing.
When selecting a unit, confirm the shaft diameter and the insert locking type: set screw, eccentric collar, or taper sleeve. Consider the sealing: in dusty or damp conditions, an insert with an additional seal is better. During installation, place the housing on a flat surface and align both housings on the shaft before tightening the screws. Lubrication is typically pre-applied at the factory; replenish according to the duty cycle and avoid solvent washing that can harm the seals.
Y-bearing housings with insert bearings can be interchanged between brands if the shaft diameter, center height, and mounting hole spacing are the same. Designations differ by manufacturer, but standardized geometry allows one unit to replace another. To verify equivalence, compare the complete part number and key dimensions; MR Industrial Accessories can assist with that cross-reference to keep your equipment running.
If you have the housing part number or the shaft diameter, send it via WhatsApp to MR Industrial Accessories and we will provide the corresponding SKF option. We can also help if you need to replace an existing unit or build a set with two housings for the same shaft.

Frequently asked questions
- What does the TH suffix mean in a TUL housing?
- The TH suffix identifies a variant within the TUL series, usually related to the sealing type or insert configuration. It does not affect the shaft diameter, which is indicated by the middle number. For the exact feature of your part number, consult the SKF data sheet.
- How do I choose between a housing with set screw and one with eccentric collar?
- The set screw locks the insert to the shaft with radial screws and works for moderate loads and solid shafts. The eccentric collar allows faster adjustment and tolerates small variations better, but requires a shaft with controlled tolerance. The choice depends on load type, speed, and how often disassembly is needed.
- Are SKF housings interchangeable with other brands?
- In general, yes, if the shaft diameter, center height, and hole spacing match. Each manufacturer uses its own nomenclature, but standardized dimensions allow replacement. Always verify the full part number and dimensions before replacing a unit.
