The DBH 8638 is a radial oil seal built to keep lubricant in and contaminants out of rotating assemblies. It measures 52 mm at the shaft, 67 mm at the housing and 7.50 mm in height, and it follows the A 095 design. You will find this seal in gearboxes, pumps, motors and other power transmission equipment. MR Industrial Accessories supplies this brand and can help you match the right seal to your application.

In the DBH line, the code 8638 identifies a specific size and style. The numbers break down as shaft 52 mm, housing 67 mm and height 7.50 mm. The A 095 configuration is a single lip with a spring, made for rotating shafts that run with lubrication. The elastomeric lip rides against the shaft to block oil from escaping, while the outer body seats in the housing bore. Because it is a wear part, plan to replace it when you see lubricant weeping or dirt getting past it.

Seals in this size range show up in gearboxes, reducers, centrifugal pumps, electric motors, drive shafts and process equipment. The job is always the same: hold oil or grease inside and keep dust, water and particles out. You will also find them in machine tools, material handling gear and hydraulic systems where a shaft turns inside a fixed housing. If the equipment sees heavy vibration or high temperature, inspect the shaft surface before you install a new seal.

When you select and install a seal like the 8638, confirm that the shaft and housing dimensions match the original part. The shaft should be clean, with no burrs or deep marks in the contact zone, and the housing must not be deformed. Put a light film of lubricant on the lip before you press it in, and keep the seal square to the bore instead of hammering on the elastomer. If the shaft is worn, a repair sleeve or a different size may be the better route. Good alignment and a sound shaft surface help the seal last.
