The DBH 5818 is a radial shaft seal from the DBH line. Its lip keeps oil or grease where it belongs and keeps dust and water out of rotating assemblies. With a 12 mm shaft, 22 mm housing and 7 mm height, it fits small, tight spots where a taller seal will not go. MR Industrial Accessories supplies this brand and helps you verify the size before you order.

Reading the code is simple: 5818 is the size reference, and Lx tells you the seal has one lip with a spring. The three figures that matter are shaft 12 mm, housing 22 mm and height 7.00 mm. Because the cross-section is small, this seal suits compact hardware where space around the shaft is limited.

You will find this size on low-power electric motors, small centrifugal pumps, speed reducers, fans, pneumatic tools and light transmission equipment. In each case the job is the same: hold lubricant inside the assembly and block outside contaminants, which helps bearings and gears last.

Before mounting, check that the shaft and bore match 12 mm and 22 mm. The shaft should be clean, with no burrs or marks, and the bore free of old sealant. Coat the lip with the same oil or grease used in the equipment, then press the seal in squarely, not at an angle. If the shaft shows wear, a seal with an extra lip is worth considering.

Need a different size or an equivalent? Send the 5818 code along with your shaft and bore dimensions. We can also source a similar design from another brand. Our team can point you to the right option based on the application and the lubricant in use.
