The DBH 1145 is a radial shaft seal built for rotating shafts. Its size is given as 75 mm at the shaft, 90 mm at the housing bore and 8 mm in height. Its job is to hold oil or grease inside the assembly while keeping dust, water and other contaminants out, which makes it a common wear part in gearboxes, pumps, motors and similar industrial equipment.

The seal carries the DBH brand and the part number 1145. The size code reads as shaft 75 mm, housing 90 mm, height 8.00 mm. Its A 012 design is a standard single-lip layout with a spring, which covers general-duty sealing. The lip is made from elastomers that resist oils and greases, so it keeps sealing while the shaft turns continuously.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. In each case it stops lubricant from escaping and blocks abrasive particles from getting in, which helps bearings and gears last longer. It shows up often in agricultural machinery, mining equipment and production lines where dependable operation matters.

When choosing a seal, match the shaft and housing dimensions to the equipment. The shaft needs suitable hardness and a fine surface finish so the lip is not damaged. At installation, coat the lip with the same oil or grease used in service, check that the spring sits correctly, avoid striking the seal and make sure it seats square to the shaft.
