DBH 9520 radial shaft seal — 50 x 92 x 8

DBH 9520 belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 9520 and any equivalents.

The DBH 9520 is a radial shaft seal with an Lx design, built to run on a 50 mm shaft inside a 92 mm housing bore with an 8 mm width. Because it carries both a sealing lip and a dust lip, it keeps lubricant in while blocking dust and dirt from reaching the bearing cavity. You will find it in gearboxes, pumps, electric motors and similar industrial equipment. MR Industrial Accessories supplies it within its seals and oil seals range.

The code 9520 identifies a radial shaft seal from DBH, and the figures in the designation tell you where it fits: shaft 50 mm, housing 92 mm, width 8.00 mm. The Lx layout pairs a primary sealing lip that rides against the shaft with a secondary lip that acts as an exclusion barrier. The designation refers to a radial seal, not an axial one, so it is read from the shaft and bore dimensions rather than from a face-mount pattern.

Gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and transmission equipment are common homes for this seal. In each case the job is the same: hold oil or grease inside the assembly and keep water, dust and chips out. Agricultural machinery, materials handling equipment and hydraulic systems also use it where the shaft turns at moderate speed and reliable sealing protects bearings and gears.

Before installation, confirm the shaft hardness and surface finish are suitable and that the housing bore is clean and free of burrs. Coat the lip with the same oil or grease the equipment uses, then seat the seal squarely. Selection depends on rotation speed, operating temperature and the fluid being retained. Lip orientation matters: facing inward it seals the internal lubricant, facing outward it guards against external contamination. With the Lx design, the dust lip always points toward the dirty side.

If you are looking for a replacement, send the code 9520 or the exact shaft, housing and width dimensions. We can suggest equivalents within the same radial seal category and help you match the design to your operating conditions. The DBH brand is part of our seals and oil seals catalog, and our team can also point you to other sizes or special-feature seals.
