The DBH 1390 is a radial shaft seal from the DBH line, built to keep oil or grease contained around a rotating shaft. It fits a 57.15 mm shaft, an 88.90 mm housing bore and a 12.00/15.00 mm height, with the A 114 single-lip, spring-loaded design. MR Industrial Accessories supplies this brand and helps you match the seal to your equipment.

Reading the code: 1390 is the size reference, and A 114 describes the sealing element, a single lip with a spring. The three dimensions are written as shaft 57.15 mm, housing 88.90 mm, width 12.00/15.00 mm. The dual height means the same seal can sit in housing depths anywhere within that 12.00 to 15.00 mm range.

Where it is used: gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment. In each case the seal holds lubricant in and keeps water, dust and particles out, which protects bearings and gears from premature wear. It is a routine item in preventive maintenance programs.

Installation points: check the shaft for burrs or a worn contact band and make sure the housing is clean and undistorted. Coat the lip with the same oil or grease used in the machine, then press the seal in square to the shaft without hitting the lip directly. If the shaft shows a deep groove, an auxiliary-lip design may be the better choice. Speed, temperature and lubricant type all influence selection.

To quote 1390, send the dimensions of your current seal (shaft, housing and height) by WhatsApp or email. We compare them against the DBH line and the other brands we carry, and confirm the option that fits your equipment. We can also tell you whether your housing accepts a different height within the 12.00/15.00 mm range.
