Description
The SKF 20X37X7 HMS5 RG radial shaft seal is designed for effective sealing between rotating and stationary machine components. Built with a rubber outside diameter, it ensures a secure and flexible fit within the housing, even when minor imperfections exist.
Its single nitrile rubber (NBR) sealing lip is reinforced with a garter spring, maintaining consistent radial pressure against the shaft to provide reliable oil and grease retention. The design offers a high pumping rate and accommodates minor shaft misalignments without compromising sealing performance.
This seal is optimized for shaft diameters of 20 mm, housing bores of 37 mm, and a width of 7 mm. It operates effectively at speeds up to 3,960 r/min, with a permissible circumferential speed of 4.12 m/s. Suitable for a temperature range from –40 °C to +100 °C, it offers dependable performance across demanding industrial and automotive applications.
