Split Eccentric Cams
Split eccentric cams are precision machined components used to create controlled vertical and horizontal movement of product across a cooling bed. By mounting the cam on a rotating shaft, the offset between the cam outside diameter and the shaft diameter converts rotation into a smooth lifting and advancing motion. The split design allows fast replacement with minimal downtime and minimal disassembly of surrounding equipment.
Split Eccentric Cams Functions
- Convert shaft rotation into controlled vertical and horizontal product movement
- Advance bars or sections step by step across the cooling bed
- Maintain repeatable stroke length based on eccentric offset
- Support consistent product spacing and alignment during cooling

Features and Benefits
- Split construction allows removal and installation without sliding the cam over the shaft ends
- No need to remove pillow blocks, couplings, or adjacent drive components during change out
- Eccentric offset can be selected to match required product lift and travel distance
- Robust materials and accurate machining for long service life in mill environments
- Reduced maintenance time and labour cost compared to solid one piece eccentrics
- Improved safety during maintenance due to shorter interventions and simpler handling
Industrial Applications of Split Eccentric Cams
Split eccentric cams are used in steel and metal mills on cooling beds and material handling lines where product must be lifted, indexed, or advanced in a controlled motion. They are ideal for retrofits or replacements on existing cooling beds where frequent change out and limited access make conventional eccentrics difficult to service.

Frequently Asked Questions (FAQs)
The difference between the cam outside diameter and the shaft diameter sets the stroke. A larger offset increases both vertical lift and horizontal travel of the product on the cooling bed.
Yes, in most cases the split design can be produced with the same effective diameter, face width, and mounting details, so it fits directly on the existing shaft and works with the current motion profile.
No. The split design allows the two halves to be removed and installed radially around the shaft, so pillow blocks, couplings, and other supports usually remain in place.
Split eccentric cams are typically manufactured from alloy steel or carbon steel with a hardness and surface finish selected for the specific load and wear conditions of the cooling bed.
High strength bolts clamp the cam halves together around the shaft. The bore and clamping surfaces are machined to provide a secure fit that transmits torque without slippage under normal operating loads.
