The DBH 9529/85 radial shaft seal is a lip seal designed to stop lubricant from escaping and prevent contaminants from entering rotating shafts. Due to its dimensions, it is used in equipment where radial space is limited and a reliable barrier against dust, water or particles is required. MR Accesorios Industriales carries this brand as part of its seals and oil seals line, with technical support to select the correct size and the right material for the application.

This DBH 9529/85 oil seal has a shaft diameter of 19.05 mm, a housing diameter of 34.64 mm and a height of 6.28/9.00 mm. Design A 135 corresponds to a single-lip configuration with spring, intended for rotating shafts at moderate speeds. The variable height indicates that the seal can be mounted in housings with different recess depths, as long as the shaft and bore dimensions are respected. It is a precision component that works in direct contact with the shaft, so surface roughness and hardness are key factors for its performance.

Radial shaft seals such as the 9529/85 are used in gearboxes, pumps, electric motors, compressors and power transmission equipment. Their main function is to retain oil or grease inside the assembly and, at the same time, prevent dust, water or chips from reaching the bearings and gears. In environments exposed to liquids or particles, this type of seal extends the service life of internal components and reduces maintenance downtime. It is also used in applications where the shaft rotates at medium speeds and lubrication conditions are controlled.

To correctly install a seal, verify that the shaft and housing diameters match the indicated dimensions. The lip must be lubricated before installation and the shaft must not have burrs or marks that could damage the seal. Concentricity between shaft and housing, as well as the perpendicularity of the support face, affect sealing performance. If the equipment operates at high temperatures or with aggressive fluids, the lip and spring material should be evaluated. In all cases, the final selection is made by comparing the manufacturer's data sheet with the actual service conditions.

If you need an equivalent seal or a nearby size, the most practical approach is to send us the full part number or the shaft, housing and height dimensions. With that data we can look for alternatives within the same brand or other lines we carry. We can also advise you on the type of lip, material and spring according to the fluid and working temperature. The more information you give us about the application, the more accurate the proposal will be.
