The DBH 5943 is a radial shaft seal that keeps lubricant in and contaminants out of rotating shaft assemblies. Its Mx design combines a sealing lip with a metal body and an internal spring for continuous contact. Because the dimensions are application-specific, the cavity and shaft should be measured before ordering.

This seal carries part number 5943. The Mx configuration refers to a lip seal with a metal outer case and a spring-loaded lip, a common arrangement for lubricated rotating shafts. The lip elastomer works together with the internal spring to maintain sealing contact against the shaft.

The dimensional data is straightforward: shaft diameter 39.69 mm, housing diameter 62 mm, height 19.05 mm. These are not interchangeable with a nearby size. A seal that does not match the cavity bore or the shaft diameter will leak or seat poorly, so confirm all three values against the equipment before replacement.

You will find this seal in gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission equipment. Its job in each case is the same: hold oil or grease in place and block dust, water and particles from reaching the bearing or gear set. Machine tools and hydraulic systems with moderate shaft speeds also use this type of seal. Where vibration or temperature runs high, a different compound may be worth reviewing.

During installation, check that the shaft measures 39.69 mm and the housing bore 62 mm, with a clean surface finish and no burrs. The 19.05 mm height has to match the cavity depth. Lubricate the lip before pressing the seal in, and use an installation tube so the lip is not rolled or cut. If the shaft shows wear, an auxiliary lip or a wear sleeve is an option to discuss. Speed, temperature and the fluid being sealed all influence the final choice.

If you need a cross-reference, send part number 5943 or the dimensions of the seal you are replacing through WhatsApp or email. We can look for equivalents in other brands or series with comparable dimensions and confirm them against your application. We can also help identify a seal from the cavity or shaft measurements.
