The DBH 5751 is a radial lip seal designed to keep oil or grease contained where a shaft rotates inside a housing, while also blocking dust and other contaminants from getting in. You will find it in gearboxes, pumps, electric motors and other power transmission equipment that relies on a rotating seal point. Its mounting dimensions are 108 mm shaft, 142.88 mm housing and 12.70 mm height.
This seal follows the Lz configuration: a single lip with a spring, made for rotating shafts that run with lubrication. The three critical measurements are shaft diameter (d) 108 mm, housing bore (D) 142.88 mm and overall height (h) 12.70 mm. Always verify these against your equipment before ordering, since a seal that is close in size but not exact will not do the job.
Seals of this size turn up in gearboxes, speed reducers, centrifugal pumps, electric motors and similar transmission assemblies where a shaft spins within a machined bore. They are also common in older or imported machines, where the original inch or metric size may not be found in standard catalogs and the specific part number becomes necessary.
When choosing and installing a radial shaft seal, consider shaft speed, operating temperature and the lubricant in use. The lip needs a shaft surface free of scratches or wear. Lubricate the lip before pressing it in, orient it toward the fluid side, and seat it squarely using a tube or shim that will not damage the seal. Remove any burrs from the housing beforehand.
For an equivalent, send part number 5751 along with your shaft and housing dimensions, plus a photo or sketch of the old seal. With that information we can search for a match from the same brand or another line. We can also check whether the size belongs to a series with different height or lip options.

Frequently asked questions
- What are the dimensions of the DBH 5751 seal?
- It fits a 108 mm shaft, a 142.88 mm housing and has a 12.70 mm height, with Lz design. Compare these three dimensions to your equipment before ordering.
- How do I know if this seal replaces the one I have installed?
- Use a caliper to measure the shaft diameter, housing diameter and height of the old seal. If they read 108 mm, 142.88 mm and 12.70 mm, it is the same mounting type.
- Can I order a size other than the one published?
- Yes. Send the part number and the dimensions you need by WhatsApp, and we will look for an alternative within the DBH line or from another brand that fits. We can also help if the old seal has no legible identification.
