The DBH 9440 is a radial shaft seal built to hold lubricant in and keep dust and dirt out of rotating equipment. Its size is defined by three values: 37 mm at the shaft, 55 mm at the housing bore, and 10 mm in height. Pressed into a cover, gearbox or housing, it protects the bearings and gears behind it. This type of seal is a common service item on gear reducers, pumps and electric motors.

The DBH 9440 follows the Lx lip design. Reading the code and the numbers together tells you what you are holding: d = 37 mm shaft, D = 55 mm housing bore, h = 10 mm overall height. An elastomer lip rides against the rotating shaft, and the outer body grips the housing bore to hold the seal in place. It belongs to the standard radial shaft seal family, used wherever oil or grease has to stay in and dust has to stay out.

You will find this seal on gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In each case it keeps lubricant where it belongs and blocks outside contaminants from reaching bearings or gears. Industrial machinery, process equipment and vehicles all use seals of this type, and a seal doing its job means less wear and fewer unplanned maintenance stops.

Before ordering, confirm that the shaft and housing measurements on your equipment match the seal. Fit it with the right tools so the lip is not damaged, put a light film of lubricant on the lip before pressing it in, and check the shaft for burrs or heavy wear. Shaft speed, operating temperature and the fluid being retained all matter when you choose the lip compound and spring.

If you need this seal under a different brand, we can look for a match. The DBH line and compatible options are both available. Send the complete part number along with the shaft, housing and height dimensions and a short note on the application, and our team will help you confirm the right choice for your equipment.
