When a rotating shaft passes through a fixed housing, the DBH 1179 radial shaft seal keeps lubricant in and contaminants out. It fits a 56 mm shaft, seats in a 112 mm housing bore and measures 8.00/10.00 mm in height under the A 293 design. This lip seal is a standard replacement item on equipment running with oil or grease, protecting the bearings and bushings behind it from dust, water and particles that shorten service life.

The part belongs to the DBH seal line and carries reference number 1179. Reading the size callout is straightforward: shaft 56 mm, housing 112 mm, height 8.00/10.00 mm, A 293 design. Those two diameters set the fit at the shaft and bore, while the height defines how much room the seal needs in the housing. The A 293 designation describes the lip and body geometry, so any replacement should match it to keep the seating and sealing behavior unchanged.

Typical installations include gearboxes, pumps, electric motors, mixers and other power transmission drives where a shaft turns inside a stationary housing. The seal also shows up on continuous process lines, where lubricant loss or incoming contamination can bring production to a halt. In these assemblies the seal works together with the bearing or bushing it shields, so its service life depends on how smooth the shaft surface is and how clean the surrounding area stays.

Before fitting a new seal, inspect the shaft for burrs or a worn sealing track and confirm the housing is clean and undistorted. Because the 8.00/10.00 mm height allows for mounting variations, verify the actual space in the housing first. Coat the lip with lubricant, press the seal in squarely to the shaft and avoid hitting it directly. If the shaft shows a pronounced wear groove, an alternative design may be the better route.

For an equivalent, share part number 1179 together with the shaft, housing and height measurements taken from the equipment. A photo of the old seal and the housing also helps. We compare those details against the manufacturer's product page and propose options within the same radial shaft seal category, so the replacement can be completed without holding up maintenance.

To request a quote, message us on WhatsApp with DBH 1179 or just 1179. If the marking on the seal is no longer readable, send the three dimensions and describe the application instead. With that information we reply with the available options and the technical details needed to confirm the installation before you buy.
