The DBH 9914 is a radial shaft seal built to keep lubricant in and contamination out where a shaft rotates. Its size is given as shaft 18 mm, housing 30 mm and height 6.40/8.00 mm, and the A 310 design covers gearboxes, pumps, motors and transmission equipment that run continuously.
Reading the code and the dimensions together is the quickest way to confirm a match. The part number 9914 belongs to the DBH line of radial shaft seals. In the size designation, 18 mm is the shaft diameter (d), 30 mm is the housing bore (D), and the height (h) is listed as 6.40/8.00 mm. The A 310 designation describes a single lip with a spring, a configuration intended for rotating shafts. Oil- and grease-resistant elastomers form the sealing element, and a metal reinforcement holds the seal steady inside the housing.
Seals of this type show up in gearboxes, centrifugal pumps, electric motors, compressors, and belt or chain drives. In each of those, the DBH 9914 keeps lubricant where it belongs and blocks dust, water and abrasive particles from reaching bearings and gears, which helps the internal parts last.
Before fitting one, verify that the shaft and the housing measure up to the stated dimensions. The shaft surface should be polished, with no burrs or grooves, and hard enough that it does not score the lip. Apply lubricant to the lip, then seat the seal with a tool that presses evenly. Because the height is given as 6.40/8.00 mm, there is a small amount of axial tolerance in the housing, which helps in tight spaces.
If you are looking for an equivalent, the team can help. The seal range covers multiple brands and sizes. Sending the part number 9914, or the three dimensions (shaft, housing and height), by WhatsApp or email speeds up the search, and our technical staff will point you to the option that fits your application.
