For equipment where a rotating shaft passes through a lubricated housing, the DBH 1336 radial shaft seal keeps oil in and contaminants out. It fits a housing bore of 47 mm and a height of 8 mm, and its design A 378 defines the lip and outer body geometry. You will find this type of seal in gearboxes, pumps, electric motors and power transmission drives.

The 1336 is part of the DBH line of radial shaft seals. Its two key dimensions are the housing bore, 47 mm, and the height, 8.00 mm, which is the space the seal occupies in the housing. The A 378 design covers the profile of the sealing lip and the outer casing, so the seal seats correctly and works against a rotating shaft.

Typical installations include gearboxes, centrifugal pumps, electric motors, rollers and conveyors. The seal also acts as a barrier where dust, chips or moisture are present. For it to work, the lip must run on a shaft surface that is ground, smooth and lubricated; a worn or scored shaft will cause leaks no matter how good the seal is.

When selecting a replacement, measure the housing bore and the available height first, then match the lip to the shaft diameter. If the shaft is worn, consider a repair sleeve or a different size. On installation, apply lubricant to the lip, press the seal evenly without striking it, and make sure the spring faces the fluid side. A clean housing helps prevent early leakage.

If code 1336 does not match your equipment or the shaft diameter is different, send us the original code, a photo of the part and your shaft and housing measurements. We can suggest an equivalent in the same brand or in another line. The more details you provide, the faster we can identify the right option.
