A radial shaft seal built to keep lubricant where it belongs and keep dust and water out. The DBH 9179 measures 48 mm at the shaft, 68 mm at the housing bore and 8.50 mm in height, and it comes in the Lx design. MR Industrial Accessories supplies this brand and helps you match the seal to your equipment.
Reading the code is the first step. The 9179 number identifies the item, while the three figures describe the fit: shaft 48 mm, housing 68 mm, width 8.50 mm. The Lx configuration uses one sealing lip with a spring, which is the arrangement normally chosen for rotating shafts.
Inside, an elastomer body and a spring hold steady contact against the shaft. That combination keeps oils and greases contained and resists the constant rubbing of normal operation without losing its elasticity.
You will find this seal in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission assemblies. In each of those spots it stops lubricant from escaping and blocks contaminants that would otherwise shorten the life of bearings and gears. Treating it as a preventive maintenance item pays off: changing it on schedule protects the whole assembly and cuts unexpected stoppages.
Before fitting a new one, inspect the shaft for burrs or wear and make sure the bore is clean and undistorted. Coat the lip with the oil or grease used in that service, then seat the seal. Peripheral speed, operating temperature and the fluid involved all influence the choice. If the shaft is already worn, an auxiliary lip version may be the better route, and shaft and housing tolerances should always be confirmed against the manufacturer's data.
Need a replacement? Send the code 9179 or the three measurements of the seal you are removing - shaft, housing and height - through WhatsApp. We compare them against the available options and tell you which one fits. If the Lx lip is not what your equipment calls for, we can point you toward a different lip style.
