The DBH 6812 radial shaft seal is a lip seal that fits between a rotating shaft and a stationary housing to keep lubricant in and contaminants out. Its dimensions—140 mm shaft, 160 mm housing, and 13 mm height—suit medium to large power transmission equipment. MR Industrial Accessories supplies this brand and can help you select the right seal for your application.
This is a DBH 6812 radial shaft seal, designated by the code 6812. Its key measurements are: shaft diameter 140 mm, housing diameter 160 mm, and height 13.00 mm. The Lx design features a sealing lip and a metal outer case, intended for press-fitting into the housing. The lip contacts the shaft with controlled interference to provide dynamic sealing.
Typical applications include gearboxes, pumps, electric motors, rollers, and transmission equipment where a shaft rotates inside a housing and oil or grease must be retained. It also serves in environments exposed to dust or water, acting as a barrier. As a wear component, the lip can harden or wear over time, leading to leaks and eventual replacement.
During installation, verify that the shaft is within tolerance and free of burrs, and that the housing has the correct diameter and depth. Lubricate the lip before insertion and use a tube or press that applies force to the metal case, never the lip. If the shaft is worn, consider a repair sleeve or an offset lip seal. Selection depends on speed, temperature, and the fluid being sealed.
For an equivalent, provide the code 6812 along with your shaft and housing dimensions. You can also send a photo of the old seal or the equipment data sheet. At MR Industrial Accessories, we cross-check the data against the manufacturer's specifications before quoting to prevent installation errors.
To request a quote, send the code DBH-6812 or the designation 6812 via WhatsApp or email to MR Industrial Accessories. With that information and your machine dimensions, we will provide a quote.

Frequently asked questions
- What are the dimensions of the DBH 6812 seal?
- The DBH 6812 has a 140 mm shaft diameter, a 160 mm housing diameter, and a 13.00 mm height. These are the dimensions indicated by the designation and product attributes. Before installation, confirm that your shaft and housing match these values.
- How do I know if this seal replaces the one I have installed?
- Compare the three dimensions: shaft, housing, and height. If they match, the seal is dimensionally compatible. Also check the lip type and material, as another configuration may be better depending on speed and fluid. Send us the data and we will help you confirm.
- What do I need to send to request a quote?
- Send the code DBH-6812 or the designation 6812 via WhatsApp or email, along with the dimensions of your shaft and housing. If you have the old seal, send a photo or measurements taken with a caliper. With that, we will quote and, if needed, look for an equivalent.
