When a rotating assembly starts weeping oil or drawing in dust, the seal is usually the first suspect. The DBH 1346 is a radial lip seal built to hold lubricant in and keep contaminants out. Its A 378 design and its 70 mm outside diameter with a 10 mm height let it sit in a standard housing bore. Pumps, motors, gear reducers and gearboxes are common homes for this size. MR Industrial Accessories supplies the DBH line and can help you confirm the right seal for the job.

Reading the code helps before you order. The 1346 designation identifies this seal, while A 378 tells you it is a single-lip, spring-loaded profile meant for a rotating shaft. The catalog lists a 70 mm housing diameter and a 10 mm height. The shaft diameter is shown as 0 mm, so that figure is not usable as printed and should be checked against the manufacturer's data or confirmed with our team before you install anything.

This seal presses into the housing and its elastomeric lip rides against the shaft, which is what creates the barrier. In a centrifugal pump, electric motor, speed reducer or gearbox, that barrier keeps oil or grease where it belongs and blocks dust, water and particles that would otherwise shorten bearing and gear life. Fan, mixer and conveyor shafts also use this kind of seal where a dependable, low-attention barrier is needed.

Sizing is not just about the 70 mm and 10 mm you see here. You also need the shaft diameter, plus the rotation speed, working temperature and lubricant type, because those factors steer the lip material choice. Fit the seal with the correct tool and clean the housing bore thoroughly; both steps have a direct effect on how long the seal lasts.
