This item is a DBH radial shaft seal, identified by the designation 8021Pol. Its standard dimensions are 85.00 mm for the shaft diameter (d), 105.00 mm for the housing diameter (D) and 9.70 mm total height (h). The Mz-R design corresponds to an oil seal with a sealing lip and spring, intended for rotating shafts. The 8021Pol nomenclature allows you to locate it within the DBH line and request the exact replacement. It is a common spare part in industrial maintenance.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment. Its function is twofold: to retain the oil or grease inside the assembly and to prevent the entry of dust, water or particles. In environments with vibration or moderate temperature, the spring-loaded lip maintains contact on the shaft. It is also used in machine tools and continuous process equipment, where a lubricant leak affects operation.

To install this oil seal, verify that the shaft measures 85 mm and the housing 105 mm, with 9.70 mm height available. The shaft surface must be polished and free of burrs; the housing, clean and free of deformation. Lubricate the lip before inserting it and place the oil seal perpendicular to the shaft, without striking it directly. If the equipment operates at high peripheral speed or temperature, consult MR to evaluate the lip material and the type of spring.
