A radial shaft seal like the DBH 5403 keeps lubricant where it belongs and keeps outside contamination out. It presses into the housing bore and rides against the rotating shaft, so it fits equipment where a shaft turns inside a housing: gearboxes, pumps, motors and transmission drives. With a 27 mm shaft, 41 mm housing and 10 mm height, it is a size maintenance departments reach for often.

The item is a DBH 5403 radial shaft seal and its designation is 5403. Its measurements are shaft 27 mm (d), housing 41 mm (D) and height 10 mm (h). The Lx design means a single lip with a spring, made for rotating shafts that run with lubrication. DBH is one of the brands we supply, so the code can be checked against the manufacturer's data sheet before the order is confirmed.

Seals of this size turn up in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In each case the job is the same: hold oil or grease inside the assembly and block dust, water and particles from coming in through the shaft passage. That is why this part appears both in scheduled maintenance and in repairs of equipment that runs continuously.

Installation calls for a look at the shaft and the housing first. Both surfaces should be free of burrs and deep scratches, with a roughness the lip can work against. Set the seal with the lip toward the lubricant side and press it in evenly, without cocking it. Lubricate the lip with the same oil or grease used in the equipment before fitting. If the shaft shows wear, a repair sleeve or a different size may be the better route.

When you need an equivalent, send the code 5403 along with the shaft, housing and height measurements. With those three values the same Lx design can be matched in another brand, always verified against the manufacturer's data sheet. A photo of the old seal and the housing also helps avoid mistakes in interpretation.

We supply seals and oil seals for industrial maintenance, and we manufacture split plummer block housings, roller chains and sheaves. To request a quote on the DBH 5403 oil seal or ask about an equivalent size, send the code through WhatsApp or email and our team will reply promptly.
