Part number 1125Vit belongs to the DBH line of radial shaft seals, the lip seals that sit in a housing bore and ride against a turning shaft. The lip holds lubricant in and keeps dust, water and particles out. Its designation reads 28 mm at the shaft, 42 mm at the housing and 8 mm in height, with an Lx-R AH design. Gearboxes, pumps, motors and transmission equipment commonly use this size as a replacement part. MR Industrial Accessories supplies this brand and assists with selection.

Reading the code helps when you order. The number 1125Vit identifies the item, while the three figures describe where it fits: shaft 28.00 mm, housing 42.00 mm, height 8.00 mm. The Lx-R AH designation covers a body shaped to seat in the cavity plus a sealing lip backed by a spring. That spring keeps the flexible lip against the shaft as it turns, so contact holds through minor misalignment or normal lip wear. You will find it filed under seals and radial shaft seals.

Where does this seal show up? Gearboxes and reducers, centrifugal pumps, electric motors, compressors and power transmission drives are the usual locations. In each case the job is the same: keep oil or grease where it belongs and block contaminants from working their way in. Fan, mixer and conveyor shafts also use it, particularly where dust or moisture is present. The small cross-section fits assemblies with limited room.

Installation decides how long a lip seal lasts. Check that the shaft and bore are clean and free of burrs or scratches, and confirm the three dimensions match the seal before you start. Coat the lip with the same oil or grease the equipment runs on. Drive the seal in with a tool that presses on the outer diameter only, never on the lip, and keep the force even. A worn shaft can be handled with a repair sleeve or by positioning the lip at a different depth. Ask us if you are unsure.

Looking for an equivalent? Send part number 1125Vit or your measured shaft, housing and height on WhatsApp. From that we can search the same brand or another line we carry. We can also tell you whether the space allows a different lip design or whether the lip material should change for your fluid and operating temperature.

MR Industrial Accessories stocks the DBH brand within its seals and radial shaft seals range. For equipment under maintenance, send part number 1125Vit on WhatsApp for a quote. A sample or the shaft and housing dimensions is enough for us to identify the part. Selection and installation advice is part of what we do.
