The DBH 6643Pol radial shaft seal is a lip seal that mounts in the housing and seals on the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 17.50 mm shaft, 28.50 mm housing and 6.00 mm height, with Lz design, place it in small-size equipment where axial space is limited. MR Accesorios Industriales sells this brand and advises you on choosing the right seal.

This item is a seal from the DBH line, identified with the code 6643Pol. Its published attributes are: shaft diameter 17.5 mm, housing diameter 28.5 mm and height 6.00 mm. The Lz design corresponds to a single lip configuration with spring, suitable for rotating shafts with lubrication. The manufacturer's nomenclature summarizes those dimensions in the code, so it is advisable to verify that the shaft and housing of your equipment match those values before replacing.

Seals of this size are used in small gearboxes, low-power electric motors, centrifugal pumps, compressors, fan shafts and transmission equipment. They also appear in machine tools, packaging equipment and compact hydraulic systems. In all cases they perform the same function: keeping oil or grease inside the assembly and preventing contaminants from entering that accelerate wear on bearings and gears.

To install it, clean the housing and the shaft, check that there are no burrs or deep marks and lubricate the lip with the same grease or oil used in the equipment. The seal must go in perpendicular, without direct blows on the lip; use a tube or shim that presses on the outer diameter. If the shaft shows wear, consider a repair sleeve. Selection depends on speed, temperature and the type of fluid, data that is best confirmed with the manufacturer.

If you need an equivalent, send us the code 6643Pol or the shaft, housing and height dimensions by WhatsApp. At MR Accesorios Industriales we check your inquiry against the manufacturer's data sheet and offer alternatives from the same brand or another line when the application allows it. The more data you send us — type of equipment, rotation speed and fluid — the more accurate the proposal will be.

MR Accesorios Industriales sells the DBH brand as part of its line of seals and radial shaft seals. If you have doubts about the compatibility of this seal with your equipment, write to us on WhatsApp with the code and the dimensions; we reply with the available technical information and, if needed, we handle the quote for the part that best fits your need.
