The DBH 1401 radial shaft seal is a lip seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 90 mm shaft, a 112 mm housing bore and has a 7.50 mm height. Pressed into the housing, it runs against the shaft to protect bearings and gears in pumps, motors, gearboxes and other industrial machinery.

With a 90 mm shaft diameter, 112 mm housing diameter and 7.50 mm height, this seal is identified by the 1401 designation. The lip contacts the shaft, usually backed by a spring for radial pressure, while the elastomeric outer body presses into a metal housing. This is one of the radial shaft seals and seals we supply.

You will find this seal in centrifugal pumps, electric motors, gearboxes, compressors and power transmission equipment. It retains oil or grease and blocks dust, water and particles that would otherwise reach the bearings. Machine tools, conveyors and agricultural equipment also use it. The 90 x 112 x 7.50 mm size suits medium-section shafts at moderate speeds. Lip material and spring choice depend on temperature and the fluid being sealed.

For proper installation, check that the shaft has the right hardness and roughness and is free of burrs or marks that could harm the lip. The housing must be clean and undistorted. Lubricate the lip with the same oil or grease used in the equipment, then insert the seal perpendicularly using a tube or press that bears on the outer diameter, never on the lip. If the shaft is worn, consider a seal with an auxiliary lip. Our technical team can help you decide.

If you need an equivalent to the DBH 1401, from another brand or with slightly different dimensions, send us the code and the dimensions you require. We can also advise you if the shaft is worn and a larger size is better. To request a quote, message code 1401 or the dimensions 90 x 112 x 7.50 mm on WhatsApp or email. We will quote it and suggest the best alternatives for your equipment.

Beyond oil seals, we stock bearings, housings, power transmission parts, seals, bushings, mounting tools and lubricants. If this seal is not exactly what you need, contact us and we will help you find the right part.
