Description
DBH 1246 belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 1246 and any equivalents.
The DBH 1246 is a radial shaft seal that keeps lubricant in and contaminants out where a rotating shaft passes through a housing. Its dimensions are compact: 17 mm shaft, 25 mm housing and 3.50 mm height, with an Lt design. That combination suits equipment with very little axial room and moderate rotation speeds, where a flexible lip must sit evenly on the shaft.
The code 1246 follows the manufacturer's size system: the first two digits give the shaft diameter in millimeters and the last two give the housing diameter. The published figures for this seal are shaft 17 mm, housing 25 mm, height 3.50 mm and Lt design. Lt means a single lip with a spring, made for rotating shafts that run with permanent lubrication.
You will find seals of this size in small gearboxes, low-power electric motors, centrifugal pumps, compressors, machine tools and transmission units. They also appear on rollers, fan shafts and drive mechanisms that turn at moderate speed and need protection from dust, water or particles.
Before installing, confirm that the shaft and housing match the published dimensions. The shaft should be ground, with suitable hardness and surface finish, and the housing needs an entry chamfer so the lip is not cut during assembly. Lubricate the lip, push the seal in squarely and keep the spring facing the fluid side. If vibration or temperature is high, ask about other materials.
For an equivalent, send the code 1246 or the three dimensions. We can source an alternative from the same brand or another brand we supply, matching tolerances and lip type. We can also tell you whether a taller seal fits the space or if a double lip is the better choice.
