When a rotating shaft needs its lubricant kept in and outside contamination kept out, the DBH 5526 does that job through a lip that rides on the shaft. Its proportions are narrow: shaft 39.69 mm, housing 52.37 mm, width 6.35 mm. MR Industrial Accessories supplies this brand and can walk you through confirming the right seal for your unit.
The reference breaks down into two parts. DBH identifies the seal family, and 5526 points to a particular size within that family's listing. The Mt designation describes a single lip with a spring behind it, which is the configuration used on lubricated rotating shafts. Quote the full code DBH-5526 when you place an order.
Seals in this cross-section turn up in gearboxes, pumps, motors, compressors and other power transmission assemblies, as well as on fan, mixer and conveyor shafts. The job is the same everywhere: hold oil or grease in place and block dust and water from getting to the bearing. In the normal elastomer temperature window and at moderate surface speeds, this style of seal works without issue.
Before fitting one, look over the shaft for burrs or grooves and make sure the bore is clean and undented. Put a film of lubricant on the lip, then seat the seal with a tube or driver of the matching diameter rather than a hammer. What you choose depends on speed, temperature, the fluid involved and system pressure, so if any of those are unclear it pays to check with our team first.
For a cross-reference, send the complete code along with the shaft, housing and width measurements, plus a photo of the removed seal if you still have it. From there we can search the DBH range and look at alternatives that fit. We can also tell you whether the Mt lip is the right call or whether a different lip profile suits your equipment better.

Frequently asked questions
- What size is the DBH 5526 seal?
- The published figures are 39.69 mm for the shaft, 52.37 mm for the housing bore and 6.35 mm for the width, with the Mt single-lip, spring-loaded design. Check those three numbers against your shaft and bore before ordering.
- How can I tell whether this seal will replace the one in my machine?
- Line up the shaft, bore and width measurements. When they match the seal you pulled out and the lip design is comparable, it should fit. If any figure differs, send us the details and we will search the DBH line for something equivalent.
- Is it possible to get a different size than the one listed?
- Yes. MR Industrial Accessories supplies the DBH line and can source other sizes and lip designs. Send the code, the dimensions and a photo of the original seal by WhatsApp or email so we can pin down the right option.
