The DBH 5212 is a radial shaft seal that keeps lubricant in and contaminants out on rotating shafts. It measures 45 mm at the shaft, 65 mm at the housing and 10 mm in height, with design A 079. Press-fitted into the housing and running against the shaft, it is commonly found in gearboxes, pumps, electric motors and power transmission equipment, where it protects bearings and prevents leaks. MR Industrial Accessories supplies this brand and helps you select the correct seal.

This single-lip seal uses a spring-loaded lip in the A 079 configuration, a standard setup for rotating shafts at moderate peripheral speeds. The lip elastomer is formulated to resist mineral oils and greases, while the metal case holds the seal firmly in the housing bore. The result is a dependable barrier against lubricant loss and against dust and water entering the assembly.

Typical installations include gearboxes, centrifugal pumps, electric motors, conveyor rollers, mixers and machine tools. The same size also appears in automotive and agricultural machinery, sealing wheel shafts, transmissions and hydraulic systems. Because 45x65x10 is a frequent size in power transmission equipment, it is often kept as a standard replacement item in preventive maintenance programs.

Installation matters as much as the part. Check that the shaft surface is free of burrs and scratches, with the hardness and roughness the application requires. Coat the lip with the same oil used in the equipment before fitting, and drive the seal in with a tube that presses on the outer diameter, never on the lip. Keep shaft and housing eccentricity within tolerance to avoid early leaks. In severe conditions, a design with an auxiliary lip or a more resistant material may be the better choice.

If you need an equivalent, send the code DBH 5212 or the shaft, housing and height dimensions. Alternatives from other brands and special configurations can be reviewed, always checking dimensional and material compatibility. Quotes are handled by WhatsApp or email, and the team can also advise on installation and on the care that helps the seal reach its full service life.
