DBH 5944 belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 5944 and any equivalents.

The DBH 5944 is a radial shaft seal with a metal case and a sealing lip, sized for a 40 mm shaft, a 62 mm housing bore and a 12.00 mm width. It keeps lubricant inside the housing and keeps dust, water and particles out, which protects bearings and gears in gearboxes, pumps and other power transmission equipment. Because it is a wear part, it is worth inspecting whenever the equipment is opened up.

In the DBH line, the 5944 code pins down one specific size, and the Mz design refers to a seal with a sealing lip and a metal body that rotates against a shaft and seats in the housing wall. If you are matching an existing seal, the 5944 number is what you give us. The three dimensions to compare are shaft 40 mm, housing 62 mm and width 12.00 mm.

You will find this seal wherever a shaft turns inside a housing that holds oil or grease: gearboxes, motors, centrifugal pumps, mixers, conveyors and machine tools. It also shows up in dusty or damp environments where contamination has to stay away from the bearing. In these assemblies the seal works alongside the bearing and the lubricant, and when it starts to fail you typically see oil loss or hear noise from the support.

Before installing, make sure the shaft is clean and free of burrs or marks, and that the sealing surface is not worn. Put a little lubricant on the lip, then insert the seal square to the shaft without striking the lip or distorting the body. If the housing has a shoulder or radius, keep to the correct mounting depth. When choosing a seal, look beyond the dimensions at the speed, temperature and fluid involved.

If 5944 is not the size you need, we can check which seal in the DBH line comes closest to your shaft and housing. Send us the shaft diameter, housing diameter and width, or simply the part number of the old seal, and we will compare it against the manufacturer's table and tell you what alternative fits. You do not have to take everything apart first; measurements from the drawing or the old part are enough.

Once you know you need the DBH 5944, send the part number by WhatsApp or email to MR Industrial Accessories and we will prepare your quote. If you are unsure, a photo of the seal or the shaft and housing dimensions is enough for us to confirm the replacement. We supply radial shaft seals for industrial equipment and can advise on installation or lip lubrication.
