The DBH 5512 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 25 mm shaft, a 47 mm housing bore and has an 8 mm overall height. Maintenance teams use it on pumps, motors, gearboxes and other power transmission assemblies where a reliable lip seal is needed. MR Industrial Accessories supplies this seal as part of its seals and oil seals range.

This seal follows the Mx design: a single lip with a spring, made for rotating shafts that run with internal lubrication. The 5512 code identifies the specific size combination within the DBH line. The lip rides on the shaft while the outer casing presses into the housing bore, creating both static and dynamic sealing.

You will find this size in centrifugal pumps, electric motors, gearboxes, compressors, mixers, and belt or chain drives. It also appears in agricultural equipment such as seeders and harvesters, and in road machinery. In every case, the seal protects bearings and stops oil or grease from leaking out and contaminating the surrounding area.

When installing, inspect the shaft for burrs or wear and make sure the lip contact surface is clean and lightly lubricated. Use a proper installation tube and apply force evenly on the casing, never on the lip. The spring must face the lubricant side. If the shaft has a deep groove, you may need to replace the shaft or choose a seal with an offset lip.

Need a replacement? Send the 5512 code or your shaft, housing and height measurements. We can also source alternatives in other brands or with special features like double lips or high-temperature materials. Our team will help you pick the right option for your equipment.
