MacDon® & Case IH® Compatible Swathmaster Center Support Idle Roller
Enhance the structural integrity of your pickup drive system with this premium C&M Australian-made center support idle roller. Specifically engineered for MacDon® and Case IH® Swathmaster canola fronts, this support roller is located in the mid-section of the belt drive roller to significantly reduce shaft flex and bowing during high-capacity operation.
Manufactured from high-performance oil-filled nylon, this self-lubricating roller provides a smooth, low-friction surface that protects the main drive roller. By utilising a reinforced internal design with six NSK bearings and integrated TC seals, this extended wear component ensures a longer service life for your feeding system, keeping your pickup front in top condition.

Expert Maintenance Review
The center support idle roller is a vital preventative maintenance component that prevents the main drive rollers from flexing under the tension of the pickup belts. When this support roller fails or the bearings seize, the drive roller can bow, leading to belt tracking issues and premature failure of the drive motor couplings. We recommend inspecting the nylon surface for flat spots and the bearings for smooth rotation during every pre-harvest check.
Upgrading to this oil-filled nylon solution is a high-performance choice. The self-lubricating properties reduce heat buildup at the contact point, while the six-bearing design offers a much higher load capacity than standard single-bearing units. This high-strength support keeps your product feeding system stable, ensuring a longer service life for your expensive pickup drive components.
Installation Tip: Verify Bolt Torque
When installing the new 8x110mm bolt, ensure it is torqued correctly to prevent the support roller from vibrating loose. Because this roller sits in the mid-section of the drive path, any looseness can cause the roller to impact the drive shaft, leading to catastrophic damage. A secure, reinforced fitment is essential for reliable operation in heavy canola swaths.
