The DBH 6175 is a radial shaft seal that keeps lubricant where it belongs and keeps dust and moisture out of equipment built around a rotating shaft. With a shaft diameter of 156 mm, a housing bore of 180.70 mm and a 12.70 mm height, it fits gearboxes, pumps and larger transmissions. MR Industrial Accessories supplies this brand and helps you confirm the right seal before you order.

Reading the code helps when you cross-reference. The designation DBH 6175 identifies the seal itself, while the Mz-R design describes how it is built: a sealing lip combined with a metal case. That construction is what holds oil or grease in place on a turning shaft. Because the dimensions follow standard housing practice, a worn seal of this size can be pulled and replaced without machining the bore.

Sizing is the first check. Shaft 156 mm, housing 180.70 mm, width 12.70 mm. The shaft and the housing must both match these figures, and the 12.70 mm width tells you how much axial room the seal needs. Measure the shaft for grooves or scoring as well; if the surface is worn, a repair sleeve or a different size may be the better route.

You will find seals of this size in gearboxes, speed reducers, centrifugal pumps, mixers and power transmission drives. In each case the job is the same: separate the lubricant from the outside environment and shield the bearings from dust, water and particles. Treat it as a wear part and inspect it at every preventive maintenance interval, since a leaking seal is often the first sign of a problem that ends in unplanned downtime.

Installation decides how long the seal lasts. The shaft surface should be smooth and free of burrs, the lip gets a light film of lubricant before it goes in, and a proper driver keeps the seal square and undamaged during fitting. Take care not to cock the seal in the bore or nick the lip on the shaft keyway.

If you need a replacement or a comparable seal, send the part number 6175 or the dimensions of your equipment. We can check alternatives within the same radial seal category and compare material and design. We also advise on applications that run at severe temperature, speed or pressure.
