The DBH 6862 is a radial shaft seal built to close the gap between a rotating shaft and its housing, holding lubricant in and keeping dust, water and particles out. Its Lx design means a single lip with a spring, and its three key measurements are 40 mm for the shaft, 52 mm for the housing bore and 7.50 mm for the height. MR supplies this brand and can help you confirm the right seal for your equipment.
Reading the code starts with the size: shaft 40 mm, housing 52 mm, height 7.50 mm. Seals in this range show up on medium-sized rotating equipment, so the 6862 is a common sight in gearboxes, electric motors, centrifugal pumps, compressors, fan shafts and belt- or chain-driven transmission assemblies. Agricultural machinery, conveyors and process lines use the same principle: keep the lubricated side separate from the outside.
The Lx lip is a single-lip, spring-loaded profile for rotating shafts where oil or grease retention matters most. The elastomer holds up against mineral oils and moderate temperatures, while the metal case keeps the seal rigid and seated in the bore. Treat it as a wear part. Once the lip stiffens or shows marks, leakage starts and replacement is the only fix.
Installation decides how long the seal lasts. The shaft must be clean, free of burrs and with the right surface finish; a scratched or worn shaft will leak even with a new seal. Coat the lip with lubricant, press the seal in square to the shaft and drive it on the outer ring with a tube or shim, never on the lip. A burred bore or a crooked fit ruins the seal. When choosing a replacement, look beyond the dimensions at the fluid, the operating temperature and the shaft speed.
If the 6862 is not the exact size, an equivalent from another brand in the same series may fit. Send the old part number, the shaft, housing and height measurements, and a photo or sample of the seal. That lets the lip profile, material and temperature range be matched so the replacement does the same job without touching the housing.
MR carries the DBH brand. If you already have the 6862 number or the measurements, send them by WhatsApp and we will quote. If all you have is the sample or hand-taken dimensions, we can help identify the seal as well.

Frequently asked questions
- What size is the DBH 6862 oil seal?
- Shaft 40 mm, housing 52 mm, height 7.50 mm, with an Lx single-lip design. If your equipment calls for a different size, an equivalent in the same line can usually be found.
- What tells me the oil seal is done?
- Lubricant weeping past the lip, a lip that has hardened or cracked, a worn spring, or marks on the shaft. Dust or water inside the housing is another sign. A worn seal left in place will damage bearings and gears.
- Can I get an equivalent if the 6862 does not fit?
- Yes. Send the part number, the shaft, housing and height dimensions, and a photo or sample by WhatsApp. The lip design, material and temperature range are compared to offer an alternative that performs the same function.
