The DBH 8137 radial shaft seal is a lip seal designed for small-diameter rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or particles, protecting bearings and mechanisms. It is press-fitted into the housing and runs on the shaft with a flexible lip that compensates for minor misalignment. It is a key component in compact equipment where space is limited and sealing is critical to the service life of the assembly.

This DBH 8137 oil seal has a shaft diameter of 4.80 mm, a housing diameter of 14.30 mm and an overall height of 6.50 mm. The Lt design corresponds to a single-lip configuration with a spring, suitable for low and medium speed applications. The lip elastomer is formulated to resist mineral oils and greases, and the outer body ensures a firm fit in the housing. It is an uncommon size, so it is advisable to verify the housing geometry before replacing it.

It is used in small electric motors, gearboxes, water pumps, fans, pneumatic tools and instrumentation equipment. It also appears in compact gearboxes, machine tool spindles and belt drive mechanisms. In all cases, its purpose is to seal the passage of lubricant and block the entry of contaminants that accelerate wear on bearings and bushings. It is commonly found in imported equipment where fine metric sizes do not follow the standard series.

To install it, clean the housing and the shaft, check for burrs or scratches and lubricate the lip with the same oil used in the equipment. Insert the seal with a support tube that presses on the outer diameter, never on the lip, and apply uniform pressure until it is fully seated. If the shaft shows wear, consider a repair sleeve or a seal with an offset lip. Selection depends on speed, temperature and lubricant type; if in doubt, consult us.

If you need an equivalent size or a seal with neighboring dimensions, send us the full part number, the shaft, housing and height dimensions, and a photo of the housing. With that data we look for alternatives in other brands or series that maintain the seal. We can also advise you on the most suitable lip design according to the shaft type and working conditions. We do not improvise sizes: we confirm every option against the catalog before quoting.
