The DBH 8113 is a radial shaft seal from the DBH line, built to hold lubricant in place and keep dust, water and particles out of rotating assemblies. Its three mounting measurements are 50.80 mm at the shaft, 65.05 mm at the housing bore and 9.00 mm in width, a combination that fits bores where there is little room along the axis. Gearboxes, pumps, motors and drivetrain components running on oil or grease are the usual homes for this reference, which MR Industrial Accessories supplies within its seals and oil seals range.

Reading the code tells you most of what you need. The 8113 block fixes the dimensional set, while the Lx designation describes the construction: one sealing lip with a spring, made for shafts that turn under permanent lubrication. The part arrives on its own, so there is no kit content or pre-assembled hardware to account for. As with any radial lip seal, the bore and the shaft have to sit inside normal machining tolerances for the lip to seat the way it should.

Where does this seal typically turn up? Gear reducers, centrifugal pumps, electric motors, conveyor rollers and belt or chain driven equipment. In each of those spots its job is the same: stop oil or grease from migrating out along the shaft and block dust, water and debris from working their way in. Moderate shaft speeds and service temperatures that stay within what the elastomer can handle are the conditions it was designed around. Equipment running with heavy vibration or shaft misalignment is a different story and may call for a stiffer body or a second lip.

Selection starts with two checks. The shaft and the housing bore must measure 50.80 mm and 65.05 mm respectively, and the 9.00 mm width has to drop into the cavity without being forced, so the lip presses evenly against the shaft. At installation, coat the lip with the same oil or grease the machine uses and slide the seal over a guide sleeve rather than the bare shaft. Shaft finish and eccentricity also shape how long the seal lasts; a surface with the right roughness and no splines under the lip works in your favor.

Need a cross to another brand? Give us the code 8113 or the measurements 50.80 x 65.05 x 9.00 mm and we will look through the radial shaft seal category for a match that keeps the same mounting dimensions. Tell us too if the housing is non-standard or if the old seal carries any special detail worth noting, so the replacement goes in without touching the equipment.

Quotes are handled by part number: send DBH 8113 over WhatsApp or email and the team comes back quickly. If the application is unclear, a photo of the assembly plus the shaft and bore measurements is enough for us to confirm a suitable option.
