The DBH 8351 is a radial shaft seal that fits on a 30 mm shaft and seats in a 45 mm housing bore, with an 8.00 mm height and an Lx design. Its job is to hold lubricant inside the assembly and keep dust, water and particles out. MR Industrial Accessories supplies this seal as part of its seals and oil seals line for maintenance and replacement work.

The code to reference is 8351 under the DBH brand. Published figures for this seal are shaft 30 mm, housing 45 mm, height 8.00 mm and design Lx. Lx identifies a construction configuration within the series; for lip geometry, elastomer and spring details, check the manufacturer's data sheet before ordering.

You will find this size on gearboxes, pumps, electric motors, rollers and other power transmission equipment where oil or grease has to stay in place and contamination has to stay out. Shafts machined to a 30 mm nominal diameter and housings bored to 45 mm are the usual match. It also serves as a replacement seal on agricultural machinery, plant equipment and continuous process lines.

Installation calls for a clean shaft and housing, no burrs or scratches, and a sealing surface without wear grooves. Apply lubricant to the lip, then press the seal in square to the shaft and avoid hitting the lip. Speed, temperature and the fluid being sealed all affect selection, so if those values are not known, check with the manufacturer or our technical team before substituting.

When you need an equivalent, send the code 8351 along with shaft, housing and height dimensions plus the operating conditions. A photo of the old seal or the housing drawing also helps. From that information we can point you to an alternative in the same series or another brand we supply, and issue the quote.

DBH is one of the seal brands MR Industrial Accessories carries. For a replacement DBH 8351, message us on WhatsApp with the code and dimensions and we will help you confirm the right part.
