The DBH 8657Pol radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or particles. With dimensions of 27 mm shaft diameter, 43 mm housing diameter and 9 mm height, it is press-fitted into covers, gearboxes and motors. It is a key part in industrial maintenance, as it protects bearings and gears from premature wear. MR Accesorios Industriales sells it as part of its seal line.

This DBH 8657Pol radial shaft seal has an Lx design, with a sealing lip and a stainless steel spring. Its dimensions are: shaft diameter (d) 27 mm, housing diameter (D) 43 mm and height (h) 9.00 mm. The body elastomer is nitrile rubber (NBR), suitable for moderate working temperatures and contact with mineral oils and greases. The outer metal case ensures a firm fit in the housing. It is a standard component within the radial shaft seal category, intended for shafts rotating at the peripheral speeds common in industrial equipment.

Typical applications include gearboxes, centrifugal pumps, electric motors, compressors, fans and belt or chain drives. It is also used in process equipment, conveyors and agricultural machinery. In all cases, the seal prevents lubricant leaks and the entry of contaminants, extending the service life of bearings and gears. It is commonly found in preventive maintenance where seals are replaced due to normal wear.

To correctly select this seal, verify that the shaft and housing dimensions match those of the equipment. The shaft surface must be ground and free of burrs; a minimum hardness of 45 HRC and a roughness Ra between 0.2 and 0.8 µm are recommended. The housing must have an entry chamfer to avoid damaging the lip during installation. Lubricate the lip with compatible grease before inserting it and use a suitable installation tube to seat it with uniform pressure. Avoid striking the seal directly.
