A lip seal such as the DBH 6849 keeps lubricant where it belongs and keeps dust, water and other contaminants out of the housing. It runs on rotating shafts and fits a 50 mm shaft, a 90 mm housing bore and a 5.00/8.00 mm height. The design reference is A 117, a lip and metal case configuration. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your equipment.

The code to quote is 6849, from the DBH brand. Read the dimensions in the usual order: shaft 50 mm, housing 90 mm, height 5.00/8.00 mm. The two height values point to a stepped profile or a lip section that sits at different depths, which gives some freedom when the housing seat is not uniform. Design A 117 uses a sealing lip with a metal case, a common arrangement for retaining oil or grease on a rotating shaft. This is a typical replacement item in industrial maintenance.

You will find this seal on gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and power transmission equipment, where it closes the gap where the shaft passes through the housing and protects both the bearings and the lubricant. Machine tools, conveyors and agricultural equipment also use it. If your shaft measures 50 mm and your housing bore measures 90 mm, it is worth checking this seal against the fluid in use and the operating conditions.

Before fitting the seal, look at shaft speed, working temperature and lubricant type. A 117 is generally run with oil or grease and needs a smooth shaft surface with no burrs. Lubricate the lip during installation and confirm the spring is seated correctly. If the housing seat is worn, consider a taller seal or a wear sleeve. Pressure and contaminant exposure should also feed into the final choice.

If you need the same dimensions or a close variant, ask us. Alternatives from other brands are available for your shaft and housing size. Send the code 6849 or the exact measurements of your equipment, and we can also point you toward a suitable lip design based on the fluid and the speed.
