A rotating shaft passing through a housing always needs a barrier where it exits, and the DBH 8412Vit radial shaft seal is exactly that barrier. Lubricant stays in, dust and water stay out. The seal fits a 30 mm shaft in a 43 mm housing bore with an 8.00 mm height, and its Mz-R lip geometry is a single lip with a spring for shafts that run under permanent lubrication. MR supplies it within its seals and oil seals range.

Reading the code: 8412Vit is the designation to quote, and DBH is the brand we supply it under. The three figures behind the seat: shaft 30 mm, housing bore 43 mm, height 8.00 mm. Lip profile matters as much as size here, because Mz-R defines how the sealing edge contacts the shaft and how the outer diameter sits in the bore. Get those two things right and the seal does its job.

Where you will run into this size: gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. In each case the seal works on two fronts at once, holding oil in the assembly and blocking outside contamination. Power transmission equipment is another common home, where a healthy seal is what keeps the bearings protected. In dirty or wet service, look at the lip condition before you decide to replace.

Installation notes that save a comeback: inspect the shaft for burrs, deep scratches or wear at the contact band, and confirm the housing is clean and not deformed. Coat the lip with the same oil or grease the equipment uses. Drive the seal in with a tube or press that pushes on the outer diameter, never on the lip itself. If the old seal failed, check alignment, shaft runout and operating temperature before fitting the new one.

Need an alternative? Send code 8412Vit, or simply the shaft, bore and height figures. From there we can search the DBH line or other brands we carry. We can also tell you whether Mz-R suits your application or whether a different lip style or material deserves a look. Equipment type, lubricant and working conditions all help us narrow the proposal.

Quotes go through WhatsApp or email: send the code or the dimensions and our team replies promptly. We help with selection and mounting questions. If compatibility with your equipment is unclear, a photo of the cover or housing gives us what we need to review it with you.
