SKF TSN ND series covers close off the ends of split bearing housings. Their job is to keep lubricant where it belongs and to block dust, water and other contaminants from reaching the bearing. We supply this line as part of our mounting and maintenance accessory range, and we help you match the cover to the housing you have.

Reading the code helps you order correctly. The number in the middle of a reference such as TSN 511 ND or TSN 520 ND tells you which housing size the cover fits. The ND suffix points to a particular design within the series. Covers are not universal across the range, so the number has to agree with the housing seat. When you ask for a quote, quote the full reference printed on the old cover or shown on the equipment drawing.

You will find these covers on split housings in pumps, fans, conveyors, mixers and mills, and on other equipment that runs continuously. In food processing, cement, mining and aggregate plants, the seal around the edge keeps grit out of the bearing and slows wear. They also suit washdown areas where water is sprayed under pressure and the lubricant must stay contained. We ship them to industrial plants throughout the United States and to several countries in Latin America.

Selection starts with the housing already on the machine. The cover reference has to match that housing. Look at the groove and the seating surface as well, because a cover that does not seat properly will leak even when the size is right. Put a little lubricant on the lip or gasket before you push the cover into place, and confirm it sits flush with the housing face. On equipment with heavy vibration, check from time to time that the cover has not worked loose.

Covers from other makers may be offered for housings built to standard dimensions. They are not automatically interchangeable: even when the housing number lines up, the fixing method, the material or the gasket can be different. Compare the drawing or the original part before you substitute another brand. If you are unsure, send us the part number and a photo of the housing and we will help you confirm the match.

To get a quote, send the complete part number and the quantity you need by WhatsApp or email. If you do not have the number handy, send the housing number or a photo of the assembly and we will identify the cover. We reply promptly, can suggest equivalent options and can help you choose the right cover for the job.
