The DBH 5774 is a radial shaft seal built to keep lubricant in and contaminants out in rotating shaft applications. This size—33 mm shaft, 56 mm housing bore, 12 mm width—fits a range of industrial equipment. MR supplies this seal and can help confirm the dimensions before you order.

This part is identified as DBH 5774, with an Mz lip design for rotating shafts. The seal is single-lip, intended for a lubricated inner side and an exposed outer side. Key measurements: shaft diameter 33 mm, housing bore 56 mm, overall width 12.00 mm.

Typical uses include centrifugal pumps, electric motors, gear reducers, gearboxes, mixers, and machine tools. It also appears on rollers, conveyors, and process machinery where retaining oil or grease and excluding dirt are critical. Always check compatibility with the lubricant, temperature range, and shaft speed.

Before installation, inspect the shaft for burrs or wear in the lip contact area and make sure the housing is clean and free of dents. Lubricate the lip, then press the seal in square to the shaft, applying force only to the outer diameter. If the shaft has a groove, consider an offset lip seal or a wear sleeve.

For a quote, send the part number 5774 along with the quantity needed via WhatsApp or email. If the old seal is unmarked, measure the shaft, housing bore, and width with a caliper, and note the lip type and material. MR can then suggest the correct DBH seal or an equivalent.

When requesting, include a photo of the old seal and housing if possible. MR’s team can verify dimensions and recommend the right option without guesswork.
