The DBH 8434 oil seal is a radial shaft seal with a 35 mm shaft diameter, 63 mm housing diameter and 16 mm height, with an A 053 design. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that accelerate wear on bearings and bushings. It is used in gearboxes, pumps, electric motors and power transmission equipment where the shaft rotates in a fixed housing. MR Accesorios Industriales supplies this official brand and advises you on choosing the right size.

This item is a single-lip radial shaft seal identified as DBH 8434. Its dimensions are 35.00 mm shaft diameter, 63.00 mm housing diameter and 16.00 mm height. The A 053 design corresponds to a spring-loaded lip configuration that ensures constant contact on the shaft. The outer elastomer allows a firm fit in the housing and absorbs small irregularities in the bore. It is a direct replacement part for equipment that already uses this standard size.

Typical applications include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and transmission shafts. In all these cases the oil seal separates the oil or grease from the outside environment and protects the bearings or bushings that support rotation. It is also used in continuous process equipment where dust or moisture shortens the service life of internal components. If the shaft shows wear or the housing is damaged, it is advisable to evaluate a repair before installing the new oil seal.

To select the correct oil seal, verify that the shaft diameter, housing diameter and height match the values of the original part. Check the condition of the shaft surface: it must be clean, free of burrs and deep marks, and with suitable roughness for the lip. Lubricate the lip before installing it and use an installation tool that presses on the outer edge, never on the lip. If the equipment runs at high speed or temperature, consult MR to evaluate the seal material.
