The DBH 1320 radial shaft seal is a lip seal mounted in cylindrical housings to retain lubricant and block the entry of dust, water or particles. Its A 378 design and dimensions of 0 mm shaft, 20 mm housing and 8 mm height place it in very small shaft applications, such as micromotors, instruments and precision mechanisms. At MR Accesorios Industriales we sell it as an official brand and advise you so you choose the correct size.

This item is a DBH 1320 radial shaft seal, identified by the designation 1320 and the A 378 design. Its published attributes are: shaft (d) 0 mm, housing (D) 20 mm and height (h) 8.00 mm. It is a lip seal with a metal body and elastomer that works on a rotating shaft or on a fixed housing, depending on how the assembly is built. The 0 mm shaft dimension indicates that it is a part for very small diameter shafts, within the precision seal line.

Typical applications for a seal of this size appear in electric micromotors, measuring instruments, optical equipment, industrial clockwork mechanisms, small pumps and low-power actuators. It is also used in laboratory machines, medical equipment and devices where radial space is minimal and oil or grease must be contained without escaping to the outside. In all those cases, the seal performs a dual function: it retains the lubricant and expels contamination.

To install it correctly, verify that the 20 mm housing is clean, free of burrs and with the entry chamfer in good condition. The lip must be lubricated before inserting the shaft, and the part must be seated squarely to avoid deforming the seal. If the shaft rotates at high speed or there is a lot of dirt, it is advisable to evaluate a spring-loaded lip or a different material. The final selection depends on temperature, fluid and working speed.

If you need an equivalent or a nearby size, send us the code 1320 together with the shaft, housing and height dimensions you have on your machine. A photo of the old seal or the assembly drawing also works. With that data we review the DBH line and the compatible alternatives, and we confirm which option fits without modifying the housing. If space allows, we can evaluate a seal of a different height within the same family.
