The DBH 5780 is a radial shaft seal built to hold lubricant in place and keep dirt out of rotating shaft assemblies. Its Mt configuration uses one sealing lip with a spring. The three figures that identify it are a 33.33 mm shaft, a 57.96 mm housing bore and a 6.35 mm width, a combination that fits equipment where axial room is tight. MR supplies this brand and helps you match the seal to the application.
Read the code as a size reference rather than a random number. The 33.33 mm value is the shaft diameter the lip rides on, 57.96 mm is the bore it presses into, and 6.35 mm is the overall width. The Mt layout means a single lip with a spring, the common choice for lubricated rotating shafts. Because the brand is one MR distributes, a replacement keeps the same geometry and material as the part it replaces.
Typical homes for a seal like this one are gearboxes, pumps, electric motors, line shafts and other process machinery. Two jobs happen at once: grease or oil stays inside the housing, and dust, water and particles stay outside. At moderate speeds, on a shaft with a suitable surface finish, this style of seal holds up well over time.
Fitting is straightforward if you check the bore and shaft first. Both surfaces should be clean and free of burrs, and the shaft finish needs to suit the lip. Put a light film of lubricant on the lip, then seat the seal square to the shaft and press it in evenly instead of hammering on the face. When a shaft is already worn, a seal positioned so the lip rides on a fresh area of the shaft can stop the leak.
If you need another size or an equivalent, the fastest route is to send the code stamped on the old seal, a photo, or the three dimensions. With that information we can search the lines we carry for a workable alternative, and we will tell you if the Mt design is not the best fit for your equipment.

Frequently asked questions
- What size is the DBH 5780 oil seal?
- It is listed as 33.33 mm shaft, 57.96 mm housing and 6.35 mm width, in the Mt design. Measuring the old seal before you order is always a good habit.
- Will this seal work in my application?
- Check that your shaft and bore match the three dimensions and that a single-lip, spring-loaded design suits the equipment. If anything is unclear, send us the machine details and we will help you confirm.
- Can MR find an equivalent for me?
- Yes. Send the shaft, housing and width measurements, or a photo of the seal you are replacing, and we will look for alternatives among the brands we supply.
