Part number 1146 from the DBH line is a radial shaft seal that keeps oil or grease where it belongs and keeps dust, water and particles out. It sits between a rotating shaft and its housing, which makes it a wear item on gearboxes, pumps, motors and other power transmission equipment. MR Industrial Accessories supplies this brand and will confirm the size with you before you commit to a quote.

Reading the designation tells you most of what you need. The 1146 seal measures 124 mm at the shaft, 152.40 mm at the housing bore and 27.00 mm in height, and it is built to design A 108, which sets the lip and metal case geometry. Those three figures are the only dimensions published for this part number. Anything else gets checked against the manufacturer's data sheet before the order is put together.

Seals in this size range turn up on large-section shafts: gear reducers, centrifugal pumps, mills, mixers, conveyors and other continuous-process machinery. You will also find them on medium-power electric motors and on heavy machinery rollers, where the job is to protect the bearing and hold the lubricant in place.

When you are matching a replacement, verify three things: shaft diameter, housing bore and cavity height. The 27.00 mm height has to fit the space you have. The shaft itself needs to be smooth, free of burrs and wear marks, because a scored or loose shaft will leak no matter how accurate the seal size is. Lubricate the lip and install it with the correct face toward the fluid being retained.

If you want to look at alternatives, send the 1146 number along with the shaft and housing dimensions you measured on the machine. From there we can check other options in the DBH line or from the other brands we carry and tell you which one drops into the existing housing without machining. We can also compare design A 108 against other lip configurations.

To get a quote, message us on WhatsApp or by email with the part number and the quantity you need. If two part numbers look equally likely, send a photo of the old seal plus the shaft measurements and we will sort out which one is correct.
