The DBH 9901/85 radial shaft seal is a lip seal that is mounted in the housing and closes on the rotating shaft to retain lubricant and block dust, water or particles from entering. Its A 100 design and dimensions of 20 mm shaft, 35.50 mm housing and 6.00 mm height make it suitable for equipment with small-diameter shafts. MR Accesorios Industriales carries this brand for industrial replacement and maintenance.

This item is a radial shaft seal from the DBH line, identified with the designation 9901/85. Its dimensions are 20 mm shaft diameter (d), 35.50 mm housing diameter (D) and 6.00 mm height (h). The A 100 design corresponds to the construction geometry of the seal. It is a rotary sealing component that works with the lip resting on the shaft and the body fixed in the housing cavity.

Seals of this type are used in gearboxes, pumps, electric motors, transmission shafts and process equipment where oil or grease must be contained and external contamination prevented. Due to its compact dimensions, it is commonly found in low- and medium-power mechanisms, fans, agitators and plant machinery. It is also used as a replacement in preventive maintenance of assemblies that already have a defined housing cavity.

To select the correct seal, verify that the shaft diameter, housing diameter and height match the values on the product page. Check the condition of the shaft surface: wear or a groove in the lip contact area can cause leaks even if the seal is new. When installing it, lubricate the lip, avoid hitting it and make sure it enters perpendicular to the housing. If the equipment operates at high temperature or speed, consult MR for a suitable alternative.
