The DBH 1351 radial shaft seal is a lip seal designed to be mounted in a 125 mm diameter housing with a height of 12 mm. Its function is to retain lubricant inside the assembly and prevent the ingress of dust, water or particles that could damage bearings and shafts. It is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales sells this brand and advises you on choosing the right seal for your application.

The DBH 1351 is a seal with an A 378 design, an outer housing of 125 mm and a total height of 12 mm. The shaft diameter shown on the data sheet is 0 mm, a value that usually corresponds to a seal with a large inner diameter or to a special designation that is confirmed against the manufacturer's technical data sheet. Therefore, before ordering it, check that the diameter of the shaft where it is mounted matches the one shown in the equipment documentation. If you have any doubts, send us the drawing or the actual measurement and we will review it together.

This type of seal is used in equipment where a rotating shaft must be sealed against a fixed housing. It appears in gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools. It is also found in applications exposed to dust or moisture, where the sealing lip must maintain tightness over long cycles. If the equipment operates with vibration or misalignment, it is advisable to evaluate a more flexible design or a seal with an additional spring.

To select the right seal, take into account the rotation speed, the working temperature and the type of lubricant. The material of the lip and the body must be compatible with the fluid and with the environmental conditions. During installation, check that the housing is clean and free of burrs, lubricate the lip before inserting it and use an installation tool so as not to damage it. Avoid striking it directly on the lip. Once in place, make sure it sits square to the shaft so that sealing is uniform.
