The DBH 5406 is a radial shaft seal with a single lip, designed to keep lubricant in and contaminants out where a shaft passes through a housing. Its dimensions are 27 mm for the shaft, 44.40 mm for the housing bore and 9.52 mm for the width, and it uses the Lz configuration. This compact size fits gearboxes, pumps and small to medium electric motors. MR Industrial Accessories supplies this brand and can quote the part number when you send it by WhatsApp.

The seal is identified as DBH 5406. The Lz design means a single sealing lip with a spring, intended for rotating shafts that run with oil or grease. The lip rides against the shaft surface, while the outer diameter presses into the housing bore. For the seal to sit square and centered, the housing must be machined to the correct diameter and depth.

Seals of this size are common in gear reducers, centrifugal pumps, electric motors, compressors and transmission equipment. They also appear on fan, mixer and conveyor shafts. Because the cross-section is small, this seal suits assemblies where radial space is tight but reliable sealing is still required.

Before installation, inspect the shaft for burrs, scratches or a wear groove in the lip contact area. A deep groove can prevent sealing even with a new part. Clean the housing and remove old sealant residue. Lubricate the lip with the same oil or grease used in the equipment. Use a tube or spacer that presses on the outer ring and drive the seal in straight; avoid pointed tools. If the application involves high vibration or temperature, contact us to review an alternative compound or design.

To find an equivalent, provide the full part number, the equipment manufacturer, or the shaft, housing and width dimensions. With that information we check the DBH line and other brands we carry for a compatible option. We can also advise if the original seal has a different design or if the housing can accept a wider seal. Accurate details help us identify the right choice quickly.

To request a quote for the DBH 5406 oil seal, send the part number by WhatsApp to MR Industrial Accessories. We will reply with the quote for that size and any alternatives in our seals and oil seals range. For preventive maintenance, ask about bearings, bushings and lubricants for the same equipment; replacing the complete assembly can be more practical than changing only the seal.
