The DBH 1161 is a radial shaft seal from the DBH line, built with an elastomeric lip and a metal ring for rigidity. It fits a housing bore of 30 mm and has a height of 8 mm, with an A 378 design. Its purpose is to keep lubricant in and contaminants out, protecting bearings and bushings from premature wear. You will find it in gearboxes, pumps, electric motors and other power transmission equipment where a shaft rotates through a fixed housing.

When selecting this seal, note the key dimensions: housing bore 30 mm, height 8 mm, and design A 378. The A 378 designation defines the lip geometry and metal body, so it should not be swapped with a different design without checking compatibility. The seal is identified by code 1161. Before ordering, verify that the shaft and housing diameters match the nominal size and that the 8 mm height fits the available space.

Radial shaft seals like this one appear in gearboxes, centrifugal pumps, electric motors, compressors, mixers, conveyors, agricultural machinery and hydraulic systems. In every case they perform two jobs: retaining oil or grease and blocking dust, water and particles that accelerate wear. Choosing the correct lip and material helps extend the service life of the bearing or bushing it protects.

During installation, lubricate the lip before sliding the shaft through, and make sure the shaft surface is free of scratches or wear in the contact area. If the shaft shows damage, consider a seal with an offset lip or a repair sleeve. The A 378 design is specific, so do not substitute it without verifying that the mounting dimensions and lip profile are equivalent.

If you need an alternative, send code 1161 along with the actual shaft and housing measurements, a photo of the old seal, and the equipment brand. With that information we can look for options in the same DBH line or in other brands we carry, always respecting the design and mounting dimensions. We can also help if the shaft diameter on the product page does not match what you measure during disassembly.
