When a rotating shaft needs to keep lubricant in and contaminants out, the DBH 1013 radial shaft seal does that job in a 52.30 mm bore. Its Mz configuration pairs a sealing lip with a retaining element, so it holds tightness while the shaft turns continuously. You will find it in gearboxes, pumps, electric motors and other power transmission assemblies where bearings and gears need protection.

Reading the size off the box is straightforward. The 1013 designation places this seal within the DBH line, and the three figures that matter are the 33.32 mm shaft diameter, the 52.30 mm housing diameter and the 11.10 mm height. The Mz design carries a main sealing lip plus a secondary exclusion lip: one keeps lubricant where it belongs, the other pushes particles away. It presses into the housing and the lip rides against the shaft.

Gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drive equipment are the usual homes for this seal. In each case the goal is the same: no oil escaping, no dust, water or chips getting in, and longer service for the bearings and gears behind it. Treat it as a wear part. When you spot leaking or hear unusual noise around the seal area, plan the replacement.

Correct selection starts with matching the shaft and housing to the figures above. The shaft surface should be polished, without grooves or burrs, and hard enough that it does not chew the lip. Keep the housing clean and undeformed. Lubricate the lip at installation with the same oil or grease the equipment runs on, and seat it without hammering. A worn shaft may call for a repair sleeve.
