A radial shaft seal from the DBH line, the DBH 8443 keeps lubricant where it belongs and keeps dust, water and particles out of the assembly. Its lip runs against the rotating shaft while its metal body seats in the housing. The size is given as shaft 100 mm, housing 125 mm and height 13.00 mm, and the design is Kx. MR Industrial Accessories LLC supplies this brand and helps maintenance and purchasing teams confirm the correct seal for the job.

Reading the reference is straightforward: 8443 is the designation of this item, and the three figures that matter are the shaft diameter (d) of 100 mm, the housing diameter (D) of 125 mm and the height (h) of 13.00 mm. Kx identifies one particular construction within the DBH range, covering how the elastomeric lip and the metal outer body are put together. Because the lip seals by contact, a seal that is even slightly off in any of those three figures will either not go in or will leak, so measure the old part before ordering.

Seals in this size range turn up in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. Their job is the same everywhere: hold oil or grease inside and keep contaminants outside. That matters most where dust, moisture or washdown is part of daily operation, since the bearing or bushing behind the seal depends on that barrier. Once the seal gives out, lubricant escapes and the wear rate on moving parts climbs.

Fitting the seal correctly is as important as choosing it. Confirm shaft, housing and height against the values above, and treat Kx as fixed unless the application has been reviewed, since another lip and body shape may behave differently. Coat the lip with the same oil or grease the equipment runs on, press the seal in square to the shaft and avoid hammer blows. A nicked lip or a seal set at an angle will leak early. If the shaft surface is worn or rough, look at repairing it or moving to a seal with greater lip coverage.

For an equivalent, send part number 8443 or the three current dimensions through WhatsApp or email. With that information we can check options in the DBH line and in other brands we supply, keeping the shaft, housing and height figures intact, and we can advise when an adaptation is the better route. Details about the equipment and the lubricant in use lead to a tighter recommendation.
