The DBH 1257Vit is a radial shaft seal from the DBH line, built to a 76.20 mm shaft, 95.40 mm housing and 17.00 mm height, with design A 407. It keeps lubricant in and contaminants out at the point where a rotating shaft leaves the housing, protecting bearings and gears in gearboxes, pumps, electric motors and power transmission equipment. MR Industrial Accessories supplies this brand and helps you confirm the right seal for your machine.

The code 1257Vit identifies this seal within the DBH range, and A 407 describes its construction: a single lip with a spring, made for rotating shafts that run with lubrication. The elastomeric lip rides against the shaft, the spring holds contact pressure, and the outer metal case seats firmly in the housing bore.

You will find this seal in gearboxes and reducers, centrifugal pumps, electric motors and transmission equipment, as well as in agricultural machinery, process equipment and hydraulic systems. In every case the job is the same: stop oil or grease from escaping and block dust, water and particles that would otherwise shorten bearing and gear life.

Before fitting, confirm the shaft measures 76.20 mm and the housing 95.40 mm, and check that the surface is smooth and free of burrs. Lubricate the lip, then press the seal in squarely using a tube that bears on the metal case, never on the lip. On a worn shaft, a seal with the lip in a different position may be the better choice. Speed, temperature and lubricant type all affect selection.

If you need an equivalent, send code 1257Vit or the dimensions of the original seal by WhatsApp or email. The team compares the options and confirms the one that fits your equipment, and can also advise when shaft or housing tolerances differ from standard.
