The DBH 6690Vit is a radial shaft seal from the MR Industrial Accessories seals line. It is a lip seal for rotating shafts, sized 30 mm shaft, 42 mm housing, and 7 mm width, with an Lz-R design. It keeps lubricant in and contaminants out of pumps, motors, gearboxes, and similar equipment.

The part number DBH 6690Vit corresponds to a seal with a 30 mm shaft diameter, 42 mm housing bore, and 7 mm overall width. The Lz-R designation refers to a lip seal with a spring that maintains contact on the shaft. It is press-fitted into the housing and seals against a rotating shaft, with the lip facing the fluid to be retained.

This seal is commonly found in centrifugal pumps, electric motors, speed reducers, gearboxes, and power transmission equipment. It also appears in agricultural machinery, process equipment, and hydraulic systems where oil or grease must be contained and bearings protected. The 30 x 42 x 7 mm size fits many standard 30 mm shafts and housings.

When selecting a replacement, confirm the shaft diameter, housing bore, and width match your equipment. The Lz-R design suits moderate shaft speeds and normal lubrication. During installation, avoid damaging the lip, lubricate it with the system oil or grease, and check that the spring is properly seated. Shaft eccentricity and surface finish affect seal life.
