FDA approved end cap ball bearing offers longer life

As with all robust xiros polymer ball bearings, the end cap is maintenance-free and guarantees low friction values for the inner and outer bearing ring, providing exceptionally long-life. Thanks to its novel tribo-polymer design, it can withstand high rotational speeds of up to 1,800rpm, and is able to resist harsh chemicals and corrosive substances. Operating temperature range is from -40°C to +80°C.

The low-weight end cap has an axial load-bearing capacity of 245N (static) and 294N (dynamic). The bearing can be customised, and it is also available with glass, plastic or stainless steel balls that are protected by a polyamide cage for strength and durability.

Typical applications include roller conveyors. Tubes with an outer diameter of 50mm can be turned into rollers by simply inserting the end cap ball bearings.

Depending on requirements, different roller lengths, thicknesses and materials are possible by simply cutting the central tube to the desired length. The outer diameter of the bearing features a number of ribs, which enable a good fit to a wider range of tube dimensions.
