The DBH 1161 radial shaft seal is a lip seal that fits housings with a 30 mm diameter and 8 mm height, with an A 378 design. Its function is to retain lubricant inside the assembly and stop the entry of dust, water or particles that accelerate wear on bearings and bushings. It is used in gearboxes, pumps, electric motors and transmission equipment where the shaft rotates on a fixed support. MR Accesorios Industriales carries this brand and helps you confirm the measurement before requesting a quote.

This item is a radial shaft seal from the DBH line, identified with the code 1161. According to the record, the design is A 378, the housing bore diameter is 30 mm and the height is 8 mm. The seal combines an elastomeric lip with a metal ring that gives it rigidity and ensures the fit in the housing.

Seals of this type are used in gearboxes, centrifugal pumps, electric motors, compressors, mixers and power transmission equipment. They also appear in agricultural machinery, conveyors and hydraulic systems where a rotating shaft passes through a housing. In all those cases the seal performs two functions: preventing oil or grease leakage and blocking the entry of external contaminants. Choosing the right lip and material extends the service life of the bearing or bushing it protects.

To install a radial shaft seal, keep three points in mind: that the shaft and housing bore diameters match the nominal measurement, that the height is suitable for the available space and that the lip is lubricated before inserting the shaft. The A 378 design defines the geometry of the lip and the metal body, so do not replace it with another design without verifying compatibility. If the shaft shows wear or scratches in the contact area, consider a seal with an offset lip or a repair sleeve.

If you need an equivalent or a nearby size, send us the code 1161 together with the actual shaft and housing bore measurements, a photo of the old seal and the equipment brand. With that data we look for alternatives in the same DBH line or from other brands we carry, always respecting the design and mounting dimensions. We can also guide you if the shaft diameter listed on the product page does not match the one you measure during disassembly.
