The DBH 9877 radial shaft seal is a lip seal designed for rotating shafts with a 17 mm diameter, a 35 mm housing and a 5 mm height. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that could damage bearings and bushings. It is press-fitted into the housing and works on the shaft with a flexible lip that maintains dynamic contact. It is a key part in low and medium power reducers, pumps and electric motors.

This DBH 9877 seal has an A 090 design and standardized dimensions: shaft diameter 17 mm, housing diameter 35 mm and height 5.00 mm. The sealing lip is intended for rotating shafts with permanent lubrication. The 9877 designation identifies the part within the DBH line, and these dimensions allow worn seals to be replaced without modifying the housing. Always check that the shaft has no splines or wear that could damage the new lip.

It is used in equipment with continuous rotation and the need to contain oil or grease: gearboxes, centrifugal pumps, electric motors, spindles and belt or chain drives. It also appears in agricultural and material handling machinery, where dust and moisture demand a reliable closure. In all cases, the seal protects the bearings and extends the service life of the assembly.

To install it, clean the housing and the shaft, check for burrs and lubricate the lip with the same grease or oil used in the equipment. Insert the seal perpendicular, without striking the lip, using a tube that presses on the outer diameter. If the shaft has play or roughness, correct it before installing. Selection depends on speed, temperature and the type of lubricant; with that data we confirm whether the A 090 design is the right one.
