The DBH 1276 is a radial shaft seal that fits into a housing and works against a rotating shaft. It keeps lubricant in and keeps dust, water and other particles out. The A 416 design calls for a 100.00 mm housing bore (D) and an 18.00 mm height (h), so it matches large-diameter shaft arrangements. MR Industrial Accessories supplies this line and can help confirm the right seal for the job.

Code 1276 identifies this seal within the DBH line, and A 416 describes the profile. The two dimensions to check first are D = 100.00 mm, the housing diameter, and h = 18.00 mm, the height. Both must line up with the bore and the depth available in your equipment.

You will find seals of this type on gearboxes, pumps, electric motors, rollers and power transmission components. They also show up on conveyors, agricultural machinery and hydraulic systems wherever a shaft turns inside a housing and a sealing barrier is required. The 100 mm bore and 18 mm height correspond to standard housing sizes used on medium and high-power equipment.

When selecting a replacement, confirm the outer diameter matches the housing and that the height fits the depth. Rotation speed, operating temperature and the lubricant in use are also part of the check. A lip that is already damaged, or a housing with burrs or nicks, will cut seal life short, so clean and lubricate the surfaces before pressing it in.

If you want an alternative from another brand, send code 1276 along with the measured shaft diameter and a photo of the old seal. With that information we can search the DBH line or other brands we carry. We can also tell you whether the A 416 profile is the right choice, or whether a different lip shape or material would work better.
