For rotating shafts that need to keep lubricant in and contaminants out, the DBH 5978 radial shaft seal is a lip seal with a compact profile. It measures 49.20 mm at the shaft, 76.22 mm at the housing and 12.70 mm in height, so it fits where axial room is tight. Common in pumps, motors, gearboxes and transmissions running on oil or grease.
This radial shaft seal carries the DBH brand and the code 5978. Its dimensions are shaft 49.20 mm, housing 76.22 mm and height 12.70 mm. The Lx design means it has a sealing lip with a spring and no external dust lip. The lip rides on the rotating shaft, while the outer diameter holds a static fit in the housing. The 12.70 mm height lets you install it in narrow spaces without giving up sealing performance.
You will find this seal in centrifugal pumps, electric motors, gearboxes, reducers and belt or chain drives. It also suits process equipment, industrial washers and agricultural machinery where oil or grease must stay contained and dust or water must stay out. The radial design works on shafts turning at moderate to high speeds, as long as the shaft surface is ground and lubrication is correct.
During installation, check that the shaft diameter is within the recommended tolerance and that the sealing surface is free of scratches or wear. The housing needs an entry chamfer to protect the lip as you insert the seal. Lubricate the lip with the same oil or grease used in the equipment. When replacing a worn seal, inspect the shaft and housing too, because a damaged surface will shorten the life of the new seal.
If you need a seal with the same dimensions, contact us with the code 5978 or with the shaft, housing and height measurements. We supply a broad range of seals and oil seals from different brands and can help you find the right option for your equipment. We also advise on lip type, material and design based on your working conditions.
