SKF TSO covers close off bearing housings. Once mounted on the housing, they keep lubricant in and keep dust, water and particles out. As housing accessories, they are chosen to match the housing and the sealing needs of the application. MR Industrial Accessories supplies them and helps you pin down the right variant using the code on the part or the equipment drawing.
In the TSO designation, the number that follows indicates the housing size it fits — TSO 218, for instance. Larger numbers go with larger housings. A suffix after the slash, such as VZ643, points to a construction or sealing variant set by the manufacturer. That is why ordering by "TSO cover" alone is not enough: two covers of the same size can differ in closure type, so the full code is required.
These covers suit bearings that run where dust, moisture or frequent washdowns are present. They show up on conveyors, pumps, fans, mixers and machines in food, chemical and cement operations. A common sight is a split plummer block housing on a drive shaft, where maintenance access is tight and an extra barrier against contamination is useful.
Selection starts with the housing: size and type must match. Then look at sealing — a labyrinth cover or a contact seal determines whether the equipment handles washdowns or only dry dust. For installation, clean the mounting surface, make sure the cover seats without force and check alignment with the shaft. If a seal is included, lubricate the lip before mounting and avoid impact tools.
SKF covers can be interchanged with those from other housing makers, but equivalence is not automatic: compare housing diameter, height and sealing type. Standard housings tend to follow similar dimensions across brands, while sealing suffixes vary. If you have the old code or the original cover, send a photo or drawing and we will check it.
To replace a cover on a housing, message us on WhatsApp with the full code — TSO 218/VZ643, for example — or with the housing dimensions. We confirm the variant and advise you so the cover seals correctly.

Frequently asked questions
- How do I order a TSO cover without the code?
- Send the housing dimensions: outer diameter, height and fixing type. A photo of the old cover or the drawing also helps. With that we identify the compatible TSO variant and quote you on WhatsApp.
- Will SKF TSO covers fit housings from other brands?
- They can, if housing diameter, height and sealing type match. There is no universal equivalence table, so dimensions must be compared one by one. Send the housing data and we will verify before quoting.
- What does a VZ suffix mean on a TSO cover?
- The suffix marks a construction or sealing variant defined by the manufacturer. It can change material, seal type or protection. To determine which variant your equipment needs, provide the full code or ask us on WhatsApp.
