The DBH 9101 oil seal is a single-lip radial shaft seal designed for rotating shafts with a 30 mm diameter. Its function is to retain lubricant inside the housing and prevent dust, water or particles from entering and damaging bearings and gears. It is press-fitted into 42 mm housings and is 10 mm high. It is a common replacement part in gearboxes, pumps and electric motors, where reliable sealing extends equipment service life.

The DBH 9101 is a radial shaft seal with an Lx design, which indicates a single sealing lip with a spring. Its dimensions are 30.00 mm shaft diameter (d), 42.00 mm housing diameter (D) and 10.00 mm height (h). The lip, generally made of elastomer, presses against the shaft by means of a spring that maintains contact pressure. The outer body is metal to ensure a firm fit in the housing. This configuration is suitable for shafts rotating at moderate speeds with continuous lubrication.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, speed reducers and transmission equipment. In all cases, the seal prevents oil or grease leaks and protects the bearings from contaminant ingress. It is also used in machine tools, conveyors and agricultural equipment. Whenever the shaft is 30 mm and the housing is 42 mm, this oil seal is a direct option to replace worn parts and restore the sealing of the assembly.

For correct installation, check that the shaft has no burrs or excessive wear in the contact area; a rough surface accelerates lip wear. Lubricate the lip before inserting it and install the seal with a press or suitable tool, applying uniform force on the outer diameter. The 10 mm height should sit flush or slightly recessed according to the housing design. If the equipment operates with high vibration or temperature, consider a more resistant lip material.
