The DBH 8046Sil is a radial shaft seal from the DBH line, built to keep lubricant in and contaminants out where a shaft turns inside a housing. Its three key measurements are 39 mm at the shaft, 74 mm at the housing bore and 11.00 mm of height, and the Lx configuration means a single sealing lip with a spring. MR supplies this brand and can help you confirm the seal before you order.

Reading the reference is straightforward: 8046Sil identifies the part, DBH is the line it belongs to, and Lx tells you the lip arrangement. Because a lip seal sits against both the shaft and the bore, those three dimensions have to match what you are replacing. Measure the shaft diameter, the housing bore and the overall height before quoting, and note the fluid and operating temperature so the lip compound can be checked as well.

Seals in this size range show up in gearboxes and reducers, centrifugal pumps, electric motors and general transmission equipment. In each case the job is the same: hold the oil or grease inside the assembly and block dust, water and other outside matter from reaching the bearing. You will also find them on agricultural machinery, material handling equipment and process lines where the shaft runs continuously. High vibration or elevated temperature is worth mentioning when you request a quote, since it affects the lip material choice.

Installation decides how long the seal lasts. Check the shaft and bore for burrs, nicks or pull marks before fitting, and coat the lip with the same lubricant used in the equipment. Press the seal in squarely so it seats perpendicular to the shaft, and use a tube or arbor press that pushes on the metal case rather than the lip. Never strike the seal directly. If the shaft surface is worn or grooved, an auxiliary lip may be the better option.

If you are cross-referencing, send part number 8046Sil or simply the shaft, housing and height measurements of the seal you are removing. Adding the equipment brand and model helps us locate the matching item. Quotes are handled by WhatsApp or email, and our team can suggest equivalents and assist with selection when the original reference is not clear.
