A rotary shaft seal that keeps lubricant inside the housing and keeps dust, water and other contaminants out is what the DBH 1398 delivers. It measures 55 mm at the shaft, 72 mm at the housing bore and 16 mm in height, and it is built to design A 053. Maintenance teams commonly pull this number when rebuilding gearboxes, pumps and electric motors. MR Industrial Accessories LLC supplies this brand and helps you confirm the correct seal for your equipment before you order.

The code breaks down simply: DBH is the seal family and 1398 is the item reference you will see on the product listing, which is what you need to match when reordering. The size string reads shaft 55.00 mm, housing 72.00 mm, height 16.00 mm. Design A 053 describes a single lip with a spring, a layout meant for a rotating shaft running inside a stationary housing bore.

Seals in this family do one job in many places: hold the oil or grease where it belongs and block what should not get in. You will find them on gearbox input and output shafts, centrifugal pumps, electric motors, conveyor rollers and machine tools. In food, chemical and process plants they help keep lubricant clean and bearings protected. On drive shafts and material handling equipment they stand between internal parts and the dust or moisture that wears them down.

Installation comes down to the shaft surface. The area under the lip needs to be smooth and free of grooves, and the bore diameter and depth have to match the seal. Wipe the lip with the same oil or grease the equipment runs on before you seat it. When a seal has already failed, look at shaft alignment, runout and operating temperature before fitting a replacement. Prying or hammering the seal into place can nick the lip and start a leak.

For an equivalent, send code 1398 along with the shaft, bore and height you measure on the equipment. A photo of the old seal and the make of the assembly also helps. MR Industrial Accessories LLC compares those details against the options we supply and comes back with a compatible choice. The more information you send, the closer the match.
