The DBH 6122 is a radial shaft seal from the DBH line, sized for a 14 mm shaft, a 22 mm housing bore, and a 4 mm height. It keeps lubricant in and contaminants out, protecting bearings, bushings, and gears. As a wear part, it is commonly replaced during preventive maintenance or when a leak appears. MR Industrial Accessories supplies this brand and can help you select the right seal for your equipment.

This seal uses the Lt design, which means a single lip with a spring, intended for rotating shafts with lubrication. The dimensions are shaft 14 mm, housing bore 22 mm, and height 4.00 mm. The number 6122 indicates the size within the DBH line. Before installation, confirm that your shaft and housing match these values exactly; even a small difference can cause leaks or poor fit.

Seals like the DBH 6122 are found in gearboxes, pumps, electric motors, compressors, machine tools, and transmission equipment. They also appear in automotive and agro-industrial applications where a shaft turns inside a housing with oil or grease. The seal works at the interface between shaft and housing, blocking lubricant escape and stopping dust, water, or particles from entering. Often, it is the primary barrier against premature wear of bearings and gears.

When choosing a seal, consider rotation speed, operating temperature, lubricant type, and differential pressure. The Lt design suits moderate speeds and low pressures. During installation, lubricate the lip with the same oil or grease used in the equipment, press the seal in perpendicular to the shaft, and avoid hitting or deforming it. If the shaft is worn or scored, repair it or use a seal with an auxiliary lip. Clean the housing thoroughly before mounting; this is critical for reliable sealing.
