For rotating shafts that need lubricant kept in and contaminants kept out, the DBH 8157 oil seal is a radial shaft seal built to the A 312 design. It fits a 70 mm shaft, a 115 mm housing bore and a 15.00 mm height. MR supplies this brand and helps maintenance and purchasing teams confirm the correct seal for the job.

The code breaks down simply: 8157 is the DBH designation, and the three measurements read as shaft 70 mm, housing 115 mm, height 15.00 mm. A 312 identifies the internal construction used in this DBH line, covering the lip profile, the body and the spring. In service, the seal closes the gap between a turning shaft and a stationary housing so oil or grease stays where it belongs and dust or water stays out.

You will find this size on centrifugal pumps, gearboxes, electric motors, compressors and power transmission equipment, as well as on agricultural, road and process machinery with rotating shafts. Because 70x115x15 mm suits medium-sized equipment, it is a common sight on maintenance shelves.

Before fitting a replacement, inspect the shaft for burrs or wear and make sure the housing bore is clean and mark-free. Apply lubricant to the lip, then seat the seal with a proper installation tube rather than striking it directly. When choosing a seal, factor in shaft speed, operating temperature and the fluid being retained.

If the old seal carries a different code, send the full marking along with the shaft, housing and height measurements and a photo of the part. From there the DBH line and other brands we carry can be checked for a match. We can also tell you whether A 312 is the right design for your equipment or whether another one fits better.
