For rotating shafts that need reliable lubricant retention and contaminant exclusion, the DBH 5522 radial shaft seal is a direct-fit solution. Its dimensions—36.91 mm shaft, 52.37 mm housing, and 4.36 mm height—match specific applications, making it a common replacement in equipment with that exact geometry. MR Industrial Accessories supplies this brand and assists in identifying the correct seal when original markings are illegible.
This seal is identified by the code 5522 and features the Mt design, which denotes a single lip with a spring. It operates on a shaft of 36.91 mm, fits a bore of 52.37 mm, and has a height of 4.36 mm. The thin-section profile is intended for tight axial spaces where a standard-height seal would not fit.
Typical uses include gearboxes, pumps, electric motors, compressors, and transmission equipment where a shaft rotates within a housing and oil must be separated from the environment. It also appears in dusty or wet conditions, where the exclusion lip blocks particles. The decimal dimensions often indicate imported machinery with inch measurements converted to millimeters.
When selecting a seal, verify three critical dimensions: shaft diameter, housing diameter, and available height. A worn or scored shaft may prevent proper sealing even if dimensions match. Ensure the shaft surface is polished and free of burrs, and lubricate the lip before installation. The Mt design is installed with the lip facing the lubricant side unless the equipment specifies otherwise.
To request a quote for code 5522, provide the old seal's dimensions—shaft, housing, and height—or a photo with a caliper. With that information, we can source an equivalent from the same brand or another with similar characteristics. We can also evaluate design variants if space permits. Accurate measurements lead to a faster replacement.

Frequently asked questions
- What dimensions does the DBH 5522 seal have?
- The DBH 5522 seal has a shaft diameter of 36.91 mm, a housing diameter of 52.37 mm, and a height of 4.36 mm. It is an Mt design with a single lip and spring. These are the dimensions you must compare before replacement.
- How do I know if this seal replaces the one I have installed?
- Measure with a caliper the shaft diameter where the lip contacts, the housing bore, and the available depth. If the values match 36.91, 52.37, and 4.36 mm, the seal fits. If there are differences of tenths, consult us before forcing installation.
- Can I ask for an equivalent if I cannot get the DBH 5522?
- Yes. Send us the original seal's dimensions or old code on WhatsApp, and we will look for an alternative from the same brand or another with similar characteristics. If space allows, we also evaluate design variants. More data yields a more accurate proposal.
