TSN L end covers are closure components for split bearing housings. They are fitted at the ends of the housing and serve two purposes: they retain the lubricant inside the cavity and prevent the ingress of dust, water or particles. They are part of the SKF accessories line that MR Accesorios Industriales supplies in Buenos Aires, Argentina. If you need to replace a damaged cover or complete an assembly, we can help you identify the part.

The designation of these covers combines the letters TSN with a number and the suffix L. The central number relates to the size of the housing they are intended for: for example, TSN 218 L corresponds to a housing of the 218 series, while TSN 507 L is associated with the 507 series. The suffix L indicates a construction variant within the family. To choose the correct cover, the safest approach is to start from the code of the housing you already have installed and ask us.

These covers are used in equipment where split housings operate in environments with dust, moisture or splashes. They are commonly found in conveyors, mills, mixers, pumps, fans and process machinery. In Argentina, the food, cement, mining and aggregate processing industries are typical settings. They also appear in plant maintenance where worn covers are replaced or new housings are assembled with genuine components.

When selecting a cover, check that the code matches that of the housing. The suffix L defines the mounting geometry and the type of closure; it is not interchangeable with other variants of the same series. Check the condition of the groove and the holes in the housing before mounting: a loose or deformed cover does not seal properly. Lubrication and bearing clearance are controlled separately; the cover only protects. If there is exposure to pressurized water, consider additional protection.

On the local market, covers from other brands with equivalent functions may appear. Interchangeability is not automatic: even if the series number matches, the material, surface treatment or fitting tolerances may vary. It is always advisable to compare the original part with the alternative and, if possible, test the fit. For repeat orders, standardizing the housing brand and its accessories simplifies maintenance and reduces replenishment errors.

If you already have the code of the housing or the cover you need, send it to us on WhatsApp. At MR Accesorios Industriales we can guide you so that the part matches your equipment. We supply SKF as an official brand and have more than 80 years of experience in the industry. Write to us with the code TSN 218 L or the one shown in your spare parts list and we will reply with the quote.
