For setups where axial room is tight, the DBH 1334 radial shaft seal offers a compact sealing solution. It keeps oil and grease in place while blocking contaminants from reaching rotating shafts. With a 47.00 mm housing and a 4.50 mm height, it fits press-in applications that protect bearings and other components in industrial machinery.

The 1334 is a radial shaft seal from DBH, built with an elastomeric lip and a metal case. Its A 378 design refers to a specific lip geometry. The housing diameter (D) measures 47.00 mm, and the height (h) is 4.50 mm. These dimensions let you confirm whether the seal will seat correctly in your housing without modification.

You will find this type of seal in gearboxes, pumps, electric motors, and transmission shafts, as well as in conveyors, agricultural equipment, and hydraulic systems where rotation is constant and lubricants are present. The low 4.50 mm height suits housings with limited axial space, as long as the shaft diameter and lip style match the speed and temperature of the application.

When selecting the 1334, check that the housing bore is 47.00 mm and that the 4.50 mm height clears without forcing. Measure the shaft diameter carefully; a poor fit leads to leaks or early wear. Also inspect shaft surface finish, concentricity, and lip lubrication. The A 378 geometry should be verified against the manufacturer's data for your specific operating conditions.

If you need a cross-reference, send part number 1334 along with your shaft, housing, and height measurements. We can look for alternatives in the DBH line or from other brands we supply. Our team can also help if the seal sees unusual temperature, speed, or fluid exposure.
