SKF TU 509 M 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 TU 509 M and any equivalents.
The SKF Y-bearing housed unit combines a cast iron housing with an insert ball bearing in one assembly, ready to slip onto a rotating shaft. It handles moderate radial and axial loads in transmission equipment, and its self-aligning design absorbs minor mounting misalignment. This makes it a practical choice both for replacing a worn housing and for new builds, since the unit arrives sealed and pre-lubricated from the factory.
The code TU … M follows a simple pattern: TU denotes the housing style, the following number sets the insert bearing size, and the final M marks a construction variant, usually tied to housing material or seal type. The insert itself carries a universal T code. For instance, a TU 504 M uses a T 204 insert, a TU 505 M uses a T 205, and a TU 506 M uses a T 206. That link to the T code lets you identify the insert on its own.
These housings are common in belt conveyors, bucket elevators, mixers, mills, centrifugal pumps, and process equipment across food, chemical, and aggregate plants. They also show up in agricultural machinery such as seeders and harvesters, and in ventilation and extraction systems. Their compact size and ability to mount in different positions suit shafts running at moderate speeds that need sturdy, easy-to-service support.
When selecting a housing, look at shaft diameter, the radial and axial load you expect, and the operating environment. Check the seal type: options include single or double lip seals, plus extra protection against dust and water. Although the unit is lubricated at the factory, inspect the insert and housing before mounting. Make sure housings are aligned and avoid impacts on the insert during installation, as these can damage the raceways and cut service life.
SKF Y-bearing housed units interchange with other brands that use the universal T insert code. For a quote, the safest approach is to give the full housing part number (e.g., TU 504 M) or the universal insert code (T 204), which prevents mix-ups between seal or material variants. If you lack the part number, send the shaft dimensions and a photo of the housing so we can identify it.

Frequently asked questions
- What does the code TU 504 M mean?
- TU stands for a Y-bearing housed unit, 504 is the size, and M is the construction variant. The matching insert has the universal code T 204. With that information you can find equivalents or request the exact replacement.
- How do I know which housing I need for my shaft?
- You need the shaft diameter and the part number of the old housing or insert. If you do not have it, send us a photo and the shaft measurements so we can identify the compatible unit.
- Are SKF housings interchangeable with other brands?
- Yes, Y-bearing housed units that share the universal T code are generally interchangeable between brands. Still, verify the sealing type and the fixing before replacing.
