Description
DBH 8755 belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 8755 and any equivalents.
A rotary shaft seal that keeps lubricant inside the housing and keeps dust, water and other particles out. The DBH 8755 is identified by its size code: 75 mm at the shaft, 122 mm at the housing bore and 12.00 mm across. Because it wears against a turning shaft, it is normally swapped out once weeping oil or contamination shows up.
The reference breaks down as follows: the 8755 code belongs to the DBH line of radial shaft seals, and the Lx designation describes a single lip with a spring. The lip rides against the rotating shaft while the outer diameter seats in the housing bore, sealing the gap between the two.
Typical service includes gearboxes, pumps, electric motors, rollers, mixers and other transmission equipment where a shaft turns inside a housing. In dusty or splash-exposed areas the seal works on both sides of the problem: it holds the oil in and blocks what is trying to get in. Maintenance crews on process lines and on agricultural or road machinery see this size regularly.
Before pressing one in, check the shaft for burrs or scoring and make sure the bore is clean and mark-free. Put a film of lubricant on the lip, then seat the seal square to the shaft instead of driving it in at an angle. When you pick a replacement, the three dimensions are only part of the decision; the lubricant in use, the shaft speed and the running temperature matter too. If the seal you are pulling out carries a different design code, compare the lip profile and the elastomer before committing.
Quotes are handled by WhatsApp or email. Send the complete code, the shaft, bore and width measurements, and a photo of the old part. With that we can search the same radial shaft seal category for a match and recommend a lip design that suits the application.
Send code 8755 or the size 75 x 122 x 12 mm and we will prepare the quote. If anything about the installation or the design is unclear, ask and we will walk you through it.

Frequently asked questions
- What size is the DBH 8755 oil seal?
- It fits a 75 mm shaft in a 122 mm housing bore with a 12.00 mm width. Those three figures come from the code itself, so confirm them against your equipment before ordering. If any measurement differs, we can search for an equivalent.
- Will the 8755 replace the seal I am removing?
- Start with shaft diameter, bore diameter and width. Then look at the lip design and the material. If the old part has a different code, send that code plus a photo and we will confirm whether the 8755 works or whether another reference is the better fit.
- How do I get a quote?
- Message us on WhatsApp or by email with the part number or the dimensions, and include a photo of the part if you have one. Our team replies promptly and can also suggest alternatives and help you choose.
