For maintenance and purchasing teams working on rotating equipment, the DBH 8240 radial shaft seal is a lip seal that sits between a rotating shaft and a stationary housing. It keeps lubricant in and contaminants out. The size is defined by three values: shaft 68 mm, housing 80 mm, height 8.00 mm. The design type is A 062. MR Industrial Accessories supplies this brand and quotes it by part number through WhatsApp or email.

You will find seals in this size range in gearboxes, centrifugal pumps, electric motors and other power transmission assemblies where a shaft turns inside a housing. The seal performs two jobs at once: it stops oil or grease from escaping and blocks dust, water and particles from reaching the bearings and bushings. Because it is a wear part, it is often replaced during scheduled maintenance.

The DBH 8240 carries the designation 8240. Its three key dimensions are shaft diameter (d) 68 mm, housing diameter (D) 80 mm and height (h) 8.00 mm. The design is A 062, which sets the lip and metal body geometry. Any replacement must match both the 68 x 80 x 8 mm size and the same design type so the lip seats correctly on the shaft.

Before installation, inspect the shaft contact area for burrs or marks and make sure the housing is clean and not deformed. Lubricate the lip with the same oil or grease used in the equipment, then press evenly on the outer diameter with a flat driver. Do not press on the lip. If the shaft shows wear, an auxiliary lip design may be worth considering. Speed, temperature and the fluid being retained all affect selection.

If you need an equivalent, send part number 8240 with the shaft and housing dimensions, a photo of the old seal and, when available, the equipment brand. That information lets us check for an alternative in the DBH line or another brand we carry. The lubricant type and operating temperature also help narrow the choice.

MR Industrial Accessories supplies the DBH brand within its seals and oil seals range. For a seal already in service, send part number 8240 and the dimensions via WhatsApp or email. The team will confirm the exact size and provide a quote.
