The DBH 5266 radial shaft seal is a lip seal that mounts on a 17 mm shaft and seals against a 40 mm housing, with an overall height of 8.50 mm. Its Lz design combines a sealing lip with a dust lip, which improves protection against dust and dirt in environments with particles. It is used in gearboxes, pumps, electric motors and power transmission equipment to retain oil or grease and prevent the ingress of contaminants.

This item is a DBH brand oil seal, identified by part number 5266. Its nominal dimensions are 17.00 mm shaft diameter, 40.00 mm housing diameter and 8.50 mm height. The Lz design corresponds to a seal with a main sealing lip and an auxiliary exclusion lip, intended for applications exposed to dust or dirt. The lip elastomer and body material are confirmed against the manufacturer's data sheet at the time of quoting.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment. In all cases it retains lubricant inside the assembly and prevents external particles from entering that would accelerate wear on bearings and gears. It is also used on fan, mixer and conveyor shafts, where the seal works in direct contact with the rotating shaft.

For installation, check that the shaft has no burrs or marks that could damage the lip, and that the housing is clean and free of deformation. The seal is pressed in with a press or a support tube that bears on the outer diameter, never on the lip. The 8.50 mm height defines the space required in the housing. If the equipment runs at high speed or temperature, it is advisable to confirm the lip material and the type of lubricant before installation.

If you need an equivalent, you can send us part number 5266 or the shaft, housing and height dimensions. We can also look for alternatives in other brands or with a different lip design depending on the type of contamination and the operating conditions. The more data you provide — speed, temperature, fluid to be retained — the more accurate the proposal will be. MR Accesorios Industriales carries this brand and can advise you on selection.
