The DBH 5641 is a radial shaft seal sized for a 50 mm shaft, a 66 mm housing bore and a 10 mm width. It keeps lubricant where it belongs and blocks dust, water and particles from reaching bearings and bushings in rotating equipment. Because it is a wear part, oil weeping or shaft movement are the usual signs that it is time to replace it.

This seal belongs to the DBH line and carries part number 5641. Its three key measurements are shaft 50.00 mm, housing 66.00 mm and height 10.00 mm. The Mz design uses a sealing lip with a metal case, a common configuration for lubricated rotating shafts. The elastomer resists oils and greases, while the case provides the rigidity needed for press fitting.

Typical installations include gearboxes, pumps, electric motors, transmission shafts and process equipment where a shaft passes through a housing. You will also find it in agricultural machinery, conveyors and power transmission systems. It suits moderate shaft speeds and temperatures within the elastomer's limits. Where vibration or misalignment is present, inspect the shaft surface before pressing in a new seal.

Selection comes down to matching the original seal's three dimensions: shaft diameter, housing bore and width. The Mz designation tells you the lip style and material, so in dirty or wet environments a version with an additional dust lip may work better. When installing, coat the lip with the same oil or grease used in the equipment, keep the seal square to the shaft and press evenly. A scored or burred shaft will damage a new seal quickly.

To quote 5641, send the measurements taken from the old seal: shaft diameter, outer diameter and height. With those three figures we can locate an equivalent in the DBH line or in another brand we supply. We can also tell you whether the Mz design fits your operating conditions or whether a different lip type or material is a better choice.
