The DBH 6249 is a radial shaft seal built to hold lubricant in place and keep dust, water and particles out of rotating assemblies. With an 18.80 mm shaft size, a 25.80 mm housing bore and a 7.00 mm height, it fits compact low- and medium-speed positions. The seal presses into the housing and its flexible lip runs against the shaft, absorbing small alignment deviations. Pumps, electric motors and gearboxes are the usual places where this part is replaced.

The code belongs to the DBH brand. Read the numbers as shaft 18.80 mm, housing 25.80 mm, width 7.00 mm, which is the order used for this type of seal. The Lt design means a single lip with a spring, a common choice for retaining oil or grease on a rotating shaft. Note that the 6249 code follows the manufacturer's size-based system; it is a seal, not a bearing, so it should not be matched against 62 series bearings.

Small centrifugal pumps, low-power motors, speed reducers, gearboxes and transmission units are typical hosts for this seal. Machine tools, compressors and lubrication systems with tight radial space also use it. Its job is to keep the lubricant where it belongs and to stop dust, water or debris from reaching bearings and gears nearby.

Before fitting a 6249, check that the shaft diameter sits within the recommended tolerance and that the running surface is smooth, with no grooves or scoring. The housing needs the correct bore and enough depth for the 7.00 mm height so the lip is not distorted. Coat the lip with the same oil or grease used in the assembly, keep the spring facing the fluid side, and press the seal in without hammering on the lip. A worn shaft can be recovered with a repair sleeve.

If you are replacing a 6249, the fastest route is to send the complete code along with the dimensions of the old seal. Shaft, housing and height measurements also work on their own. Our team reviews options in the same seal category and comes back with compatible choices. When the original part has no readable brand, a photo next to a caliper is usually enough for identification.
