Compact bearing DAC 4278, Ø 42/78 x 45 mm waterproof, for wheel brake BPW S 2504-7 RASK
The compact bearing DAC 4278 is a double-row angular contact ball bearing for the wheel bearing arrangement on trailer axles. As a closed unit, it takes up radial and axial loads together. As a replacement part, it fits the wheel hubs of BPW axles with the S 2504-7 RASK wheel brake.
Selection is based on the inner and outer diameter and the width of the fitted bearing. When pressing it in, apply force via the outer ring only and tighten the axle nut to the torque specified by the axle manufacturer. Do not refit a bearing that has been pressed out.
