When a rotating shaft needs to keep lubricant in and contamination out, the DBH 6648 radial shaft seal is the part that does the job. It measures 57.15 mm at the shaft, 85.09 mm at the housing bore and 12.70 mm in height, and its Lz design covers a sealing lip with a spring. Maintenance teams use it on pumps, gear reducers, electric motors and other transmission equipment. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your application.
The code 6648 identifies this radial shaft seal within the DBH line. Reading the dimensions in order makes selection easier: shaft 57.15 mm, housing 85.09 mm, width 12.70 mm. The Lz configuration means a lip with a spring, a setup intended for rotating shafts that run with oil or grease. Because the seal sits in direct contact with both the shaft and the housing bore, matching those two diameters and the width correctly is what keeps the assembly leak-free.
You will find this seal in gearboxes and reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In each case it serves as the barrier that holds lubricant inside while blocking dust and moisture from reaching bearings and gears. Machine tools, food processing equipment and hydraulic systems also rely on this kind of seal wherever a rotating part meets a stationary one.
Installation calls for a clean shaft and housing, with no burrs or scratches on either surface. Coat the lip with the same oil or grease the equipment uses, then press the seal in perpendicular to the shaft with a proper tool rather than striking the lip directly. Speed, operating temperature and the fluid in use all affect selection. A worn shaft may call for a seal with an auxiliary lip. If anything is unclear, send us the exact dimensions and we will review it.
