The DBH 5766 is a radial shaft seal built to hold lubricant in and keep dust and moisture out of assemblies with rotating shafts. Its Mz design combines a single sealing lip with a metal outer case, and the seal presses into a cylindrical housing bore. With a shaft size of 33.33 mm, a housing bore of 50.80 mm and a width of 11.90 mm, it fits gearboxes, pumps, motors and transmission shafts. MR supplies this brand and can help you confirm the right seal for your lubricant, speed and operating conditions.

The reference 5766 identifies this seal within the DBH catalog, and the Mz designation tells you it is a single-lip, metal-cased radial shaft seal made for press fitting. Reading the code together with the dimensions is the quickest way to confirm a match: shaft 33.33 mm, housing 50.80 mm, width 11.90 mm. MR supplies DBH as one of the brands in its sealing range, and the same reference can be cross-checked against the catalog when you send it in.

Seals in this size range turn up in gearboxes, centrifugal pumps, electric motors, compressors and transmission shafts. In each case the job is the same: keep the oil or grease where it belongs and stop outside contaminants from reaching bearings and gears. The narrow 11.90 mm width suits equipment where radial room is tight but dependable sealing is still required at moderate speeds.

Installation calls for a clean shaft and bore, with no burrs, scratches or leftover sealant. Coat the lip with the same lubricant the equipment uses before you press the seal in. Depending on the cover design, the 11.90 mm width should end up flush with the housing or slightly below it. If the shaft surface is worn, an auxiliary lip version may be the better route. Speed, temperature and lubricant type all feed into the final choice.

If you are looking for a replacement for the DBH 5766, send the code, the three dimensions or a photo of the part. The team checks the designation against the catalog and can propose alternatives from the same brand or from other brands in the range. That also applies when the housing runs to special tolerances or the shaft is worn enough that a repair size makes more sense.

Quotes are handled by WhatsApp or email. Send the code and the team replies promptly with purchasing options and, where useful, equivalent references. MR Industrial Accessories supports plants, factories and maintenance crews across the United States and in several Latin American countries with sealing and power transmission products.
