The DBH 1121Pol radial shaft seal is a lip seal designed to close off lubricant passage and prevent contaminant ingress on rotating shafts. With dimensions of 42 mm shaft, 58 mm housing and 11 mm height, and design A 368-R AH, it is installed in gearboxes, pumps, motors and transmission equipment. MR Accesorios Industriales carries this official brand and advises you on choosing the right seal for your application.

This item is a radial shaft seal from the DBH line, identified with part number 1121Pol. Its nominal dimensions are 42 mm shaft diameter, 58 mm housing diameter and 11 mm height. Design A 368-R AH corresponds to a seal with a sealing lip and a specific construction configuration for retaining oil or grease on a rotating shaft. The exact designation lets you verify the match with the housing and shaft before installation.

Radial shaft seals like the DBH 1121Pol are used in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. Their function is to keep lubricant inside the assembly and block dust, water or particles that could wear the bearings. They are also used in applications with low differential pressure and continuous rotary motion, provided the speed and temperature are compatible with the lip material.

To select the correct seal, verify that the shaft and housing diameters match the values in the data sheet. The 11 mm height must fit into the cavity without forcing. During installation, lubricate the lip with the same service oil or grease, insert the seal perpendicular to the shaft and avoid hitting the lip with tools. If the shaft shows wear or grooves, evaluate a repair sleeve or an alternative size.
