The DBH 8158 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions —111.31 mm shaft diameter, 142.80 mm housing diameter and 4.92 mm height— make it suitable for equipment where axial space is limited and a reliable barrier against leaks is required. MR Accesorios Industriales carries this brand, with more than 80 years of experience in the field, and advises you so you choose the right oil seal for your application.

This item is a radial shaft seal of the DBH brand, identified by code 8158. According to the record, its dimensions are: shaft diameter (d) of 111.31 mm, housing diameter (D) of 142.80 mm and height (h) of 4.92 mm. The A 045 design corresponds to a single-lip configuration with a spring, intended for rotating shafts. It is a sealing component that works in direct contact with the shaft and the housing, so its correct selection depends on the tolerances and surface finish of both parts.

Radial shaft seals such as the DBH 8158 are used in gearboxes, pumps, electric motors, rollers and power transmission equipment. Their main function is to prevent the escape of oil or grease and the entry of dust, water or particles that accelerate the wear of bearings and gears. In applications with large-diameter shafts and little axial space, this type of low-height seal is a practical solution for keeping lubrication contained.

To install an oil seal correctly, check that the shaft and housing diameters match the dimensions indicated. The shaft surface must be free of burrs, with hardness and roughness suitable so as not to damage the lip. During installation, lubricate the lip with the same oil as the equipment and use an installation tool that applies uniform pressure on the outer ring. Avoid striking the seal directly, since you can deform the lip or the spring.
