SKF TK end covers close off the ends of split and solid bearing housings. Their job is to hold lubricant in, keep dust and moisture out, and in certain designs help position the bearing. MR Industrial Accessories LLC supplies this line as part of its range of housings and accessories for assembling and maintaining rotating equipment.
The TK prefix covers end covers and related housing accessories. The number that follows tells you the size or the housing-cover pairing. For instance, TK 34 and TK 38 are covers for housings of different sizes, while TK 38/160 and TK 40/150 carry an extra dimension, usually the outside diameter or the housing width. Codes TK 228 and TK 509 belong to covers for larger or heavy-duty housings. To get the right cover, match its code against the SKF housing it will be fitted to.
You will find these covers on bearing housings in conveyors, bucket elevators, mills, mixers, centrifugal pumps and industrial fans. Plants handling food, cement, mining, paper and aggregates rely on them where dust, moisture or washdown demand effective sealing. They also appear on line housings for transmission shafts and in applications with continuous rotation.
Selection starts with confirming that the cover code matches the housing series and size. Then look at the sealing the equipment needs: covers can be blind or supplied with a seal, and some include a labyrinth for extra protection. At assembly, check alignment between cover and housing and make sure the bearing is properly lubricated before you close it. In dirty or wet areas, go with a sealed or labyrinth cover and verify axial clearance.
SKF TK end covers can be swapped with those from other housing makers, but equivalence is not automatic. Compare mounting dimensions, outside diameter, width and fixing method; a matching number alone is not enough. If anything is unclear, ask your supplier or send a photo of the cover and the housing so compatibility can be confirmed before you request a quote.

Frequently asked questions
- How do I know which TK end cover fits my housing?
- You need the SKF housing code. The TK cover is selected by series and size compatibility. If you do not have the code, send a photo of the housing and its main dimensions via WhatsApp and we will help you identify it.
- Can TK end covers be used on housings from other brands?
- They may work if the mounting dimensions and fixing type match. A similar number is not enough. Compare outside diameter, width and retention system, or consult us with the housing data.
- What is the difference between a blind end cover and one with a seal?
- A blind end cover closes the housing end and retains lubricant. A cover with a seal adds a lip that rubs against the shaft to improve protection against dust and water. The choice depends on the working environment.
