Part number 6758 belongs to the DBH line of radial shaft seals, a lip seal that sits between a turning shaft and a stationary housing. It keeps lubricant where it belongs and keeps dust, water and other debris out. The three dimensions to match are shaft 44.45 mm, housing 68.22 mm and height 15.87 mm. Sizes like this show up in gearboxes, pumps, motors and other power transmission equipment built around medium-section shafts. We supply this brand and will confirm the size with you before you send a quote request.

The 6758 carries the Kx design, which means a sealing lip combined with a metal case for a rigid housing bore. The code tells you the line and the design; the dimensions tell you whether it fits. Nothing else varies under this part number, so treat the figures above as the specification and check them against your drawing or the part you are removing before you commit to a replacement.

Seals in this size range turn up in gearboxes and speed reducers, centrifugal pumps, electric motors, rollers, mixers and continuous process lines. Wherever a shaft rotates inside a fixed bore, the seal does two jobs at once: it holds oil or grease on the inside and blocks contamination from the outside. Both functions matter, because a seal that only half works will still let the bearing fail.

Installation decides how long the seal lasts. The shaft needs to be clean, with no burrs, nicks or scratches on the sealing surface, and the bore should be just as sound. Seat the seal square to the shaft and drive it in with a tube or spacer that presses on the outer ring, never on the lip. Wipe the lip with the same oil or grease the equipment runs on before you slide it into place. A worn shaft or a marked bore will leak no matter how accurate the size is.

If you are looking for an equivalent, send part number 6758 together with the shaft and housing dimensions. A photo of the old seal or the assembly drawing works just as well. From there we check options in the same DBH line or from other brands we carry and tell you which one fits without machining the housing. The dimensions alone are enough; you do not need the exact number to start.
