The DBH 8434 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 35 mm shaft, a 63 mm housing bore and has a 16 mm overall width, and it follows the A 053 lip design. This seal is commonly found in gearboxes, pumps, motors and similar assemblies where a shaft turns inside a fixed housing. MR Industrial Accessories supplies this brand and helps you match the correct size for your application.

This component is a single-lip radial shaft seal. Its key measurements are: shaft 35.00 mm, housing 63.00 mm, width 16.00 mm. The A 053 designation means the lip is backed by a spring that maintains steady pressure against the shaft. The rubber outer case grips the housing bore and compensates for minor surface imperfections. It serves as a drop-in replacement for equipment that already uses this standard size.

You will typically find this seal in gear cases, speed reducers, centrifugal pumps, electric motors, compressors and transmission shafts. In each case it isolates oil or grease from the surrounding environment and shields the bearings or bushings that carry the rotating load. It also appears in continuous-duty processes where dust or moisture would otherwise shorten the life of internal parts. If the shaft shows wear or the housing is damaged, consider repairing those surfaces before installing a new seal.

When selecting a replacement, confirm that the shaft diameter, housing bore and width match the original. Inspect the shaft surface: it should be clean, free of burrs or deep grooves, and have a finish suitable for the lip. Apply lubricant to the lip before installation and use a driver that presses on the outer edge, never on the lip itself. For high-speed or high-temperature service, consult MR to review the seal material.
