Sintered Tractor Clutch Plates & Counter Steel Plates: A High-Performance Friction System
In a tractor clutch assembly, the sintered copper-based friction disc and the counter steel plates (the flywheel and pressure plate surfaces) form an indispensable high-performance friction pair. They are engineered to work in unison under extreme conditions to ensure reliable power transmission.
The Role of Counter Steel Plates
Counter steel plates refer to the precisely machined and hardened friction surfaces of the flywheel and pressure plate. They are the "dance partners" to the sintered clutch disc, and their performance is just as critical.
Their primary functions are:
Providing a Friction Surface: To engage with the sintered disc and transmit engine torque through friction.
Heat Dissipation: To act as a heat sink, absorbing and dissipating the immense heat generated during clutch engagement and slippage.
Ensuring Clean Disengagement: To provide a smooth, flat surface that allows for instant release when the clutch pedal is depressed, preventing drag.
For optimal performance and longevity, always ensure the entire friction system is in perfect condition. Resurface or replace any damaged counter plates to protect your investment.
Choose Our Matched Systems for Unbeatable Durability
We offer premium-quality sintered clutch discs and engineered counter plates. Using our matched systems guarantees perfect compatibility, maximum torque capacity, and the longest possible service life for your tractor's clutch under the most demanding agricultural workloads.
Why Our Counter Steel Plates Are Engineered for Excellence
Ordinary steel cannot withstand the aggressive nature of sintered copper-based friction materials. Our counter plates are specially designed to match their demanding partner, offering:
Exceptional Surface Hardness: The friction surfaces undergo specialized heat treatment (e.g., induction hardening) to achieve a very high surface hardness. This prevents rapid wear and grooving caused by the hard sintered disc.
Superior Wear Resistance: The hardened surface ensures excellent longevity, aiming for a service life equal to or greater than that of the clutch disc itself.
Excellent Thermal Stability: They retain their mechanical strength and hardness even at high temperatures (up to 600-700°C), resisting the softening (annealing) that leads to failure.
High Resistance to Thermal Cracking: The material and manufacturing process are optimized to resist the formation of heat-check cracks (craze cracking) caused by repeated thermal cycling, which can lead to surface degradation and chatter.
Precision Machining: Each plate is machined to exacting standards of flatness and parallelism to ensure smooth engagement, even pressure distribution, and minimal vibration.

We produces also for OEM-customers.
