When a rotating shaft passes through a housing, the DBH 1298 radial shaft seal keeps lubricant in and contaminants out. It is a single-lip seal sized for a 20 mm shaft, a 26 mm housing bore and a 4 mm height. Because it is a wear item, leakage or shaft movement usually signals it is time to replace it.
The dimensions of this seal are a 20 mm shaft diameter, a 26 mm housing diameter and a 4.00 mm height. Its Lt configuration means a single lip with a spring, which is intended for rotating shafts that run with lubrication. DBH is one of the seal lines MR carries, so if this exact code does not suit your application, ask about other options.
You will find this type of seal in gearboxes, pumps, electric motors, rollers and other power transmission equipment where a shaft turns inside a housing and needs to be sealed. It also shows up in agricultural and industrial settings with moderate dust and moisture. In every case it works together with a bearing or bushing, holding the lubricant in place and helping the assembly last longer.
Before installation, confirm the shaft dimensions and surface finish, and check for burrs or marks. Put some lubricant on the lip, then press the seal in squarely so it sits perpendicular to the shaft and the lip is not damaged. If the housing bore is worn, a seal with a greater height may be an option. Speed, temperature and the type of lubricant all play a role in choosing the right seal.
If you need a different size or an equivalent, send the code stamped on the old seal along with the shaft and housing dimensions and a photo. With that information we can search the DBH line or other brands we supply for a match. We can also let you know whether the space allows a taller seal or a design with an extra lip.
