Brake Drum / Oil Hub
Its robust cast-iron construction withstands high braking temperatures while the oil-hub design ensures constant lubrication of the bearing area, reducing friction and improving reliability. The drum’s precision-machined braking surface provides uniform shoe contact, resulting in smooth, consistent braking performance. Its enhanced thermal stability reduces brake fade during heavy-duty operations, making it ideal for long-haul and high-load trucks.
By combining braking functionality with hub oil-lubrication compatibility, this drum ensures optimal durability, smoother operation, and lower maintenance costs throughout the vehicle’s lifecycle.
