The DBH 8972 radial shaft seal is a lip seal designed for rotating shafts with a 70 mm diameter, a 110 mm housing and a 10 mm height. Its function is to retain the lubricant inside the assembly and block the entry of dust, water or particles that could damage bearings and gears. It is press-fitted into the housing bore and runs on the shaft, with a flexible lip that maintains dynamic contact. It is a wear part: it should be checked at every teardown and replaced if it shows hardening, cuts or loss of elasticity.

This item is a DBH brand oil seal, identified with code 8972. Its dimensions are shaft (d) 70 mm, housing (D) 110 mm and height (h) 10 mm. The Lx design corresponds to a single-lip seal with a spring, intended for rotating shafts with internal lubrication. The DBH 8972 nomenclature makes it easy to locate in the catalogue and compare it with other brands that use the same numeric designation. If you need to confirm the exact design or the lip material, we verify it against the manufacturer's data sheet before quoting.

Typical applications for a 70x110x10 mm oil seal are gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases it performs the same function: confining the oil or grease inside the assembly and preventing contaminants from entering from outside. It is also used in agricultural and road machinery and in process equipment where the shaft rotates continuously and there is dust or ambient humidity.

To install it correctly, keep in mind that the housing must be clean, free of burrs and with the right tolerance for a press fit. The lip is lubricated before insertion and runs on a shaft surface free of splines or deep marks. Selection depends on rotation speed, working temperature and the type of fluid to be retained. If the original seal failed due to heat or abrasion, it is worth evaluating a different compound or a design with an auxiliary lip.

With that data we look for the equivalent in DBH or another brand we carry, or we offer you the closest size within the same series. We can also review whether the Lx design is the most suitable for your application or whether it is better to move to another type of lip.
