This item is a DBH 1234 radial shaft seal, identified by the designation 1234. According to the product page data, it has a housing bore of 69.85 mm and a height of 8.00 mm. Design A 378 defines the lip profile and the case type. It is a sealing component that works on the rotating shaft and seats in the housing cavity, with the aim of containing lubricant and blocking external contaminants.

Typical applications of this oil seal include centrifugal pumps, electric motors, reducers, machine tool bearings and transmission equipment. In all cases, the function is the same: keep oil or grease inside the assembly and prevent the entry of particles, water or dust that accelerate wear. It is a critical part in maintenance, because its failure causes leaks and can damage nearby bearings and gears.

To install a seal like this, verify that the shaft diameter, housing bore and height match the values on the product page. The shaft surface must be clean, free of burrs and marks, and it is advisable to lubricate the lip before inserting it. Design A 378 may require a specific lip orientation; if you have doubts, ask us. It is also important to check the condition of the housing and use a suitable tool so as not to deform the case during installation.
