820788 suitable for Claas Pick up cam will fit Claas Markant Rollant

The CLAAS 820788 is a high-performance component designed for demanding agricultural applications, offering exceptional durability, reliability and operational efficiency. Its advanced engineering construction ensures optimum performance in a variety of operating conditions.

Strong Adaptability
Designed specifically for CLAAS agricultural machinery, it precisely matches the QUADRANT series square balers (such as QUADRANT 5300 RC, 4000, etc.) and ROLLANT series round balers (such as ROLLANT 540 RC) in terms of model compatibility. In terms of dimensions, it adopts an integrated forging process, with a length of approximately 350mm and a thickness of 28mm, which is suitable for the standard wheelbase of CLAAS baler camshafts (such as the 2.10-meter pickup wheelbase of the ROLLANT series). The machining tolerance is controlled within ±0.02mm, and the mounting holes are standard M12×1.75 threaded holes, compatible with CLAAS original bolts. This series of designs ensures convenient installation, precise matching with equipment specifications, stable operation, and fundamentally avoids failures caused by adaptation issues.

High Performance
Manufactured using advanced engineering technology, in terms of power transmission efficiency, the cam curve is optimized through finite element analysis, reducing transmission torque loss by 15%. It can still maintain a power transmission efficiency of over 98% in high-humidity environments (such as silage baling) or low-temperature (-20℃) conditions. At the same time, it has a built-in elastic buffer structure, which can withstand instantaneous overloads (such as straw blockages) up to 1.5 times the rated load, and can maintain excellent performance in various high-demand agricultural operating environments such as complex terrain and high-intensity operations, effectively improving the working efficiency of the equipment. For example, in the QUADRANT 4000 square baler, the use of this component can increase the baling speed to 120 bales per hour, which is 12% higher than traditional components, and is especially suitable for high-density baling of high-fiber crops such as corn stover and alfalfa.

Outstanding Durability
It is made of high-strength alloy steel (tensile strength ≥800MPa), which is quenched and tempered to improve fatigue resistance. The surface is treated with high-velocity oxygen fuel (HVOF) cobalt-based tungsten carbide coating, with a thickness of 0.3mm and a hardness of up to 1000-1400HV. The coating porosity is less than 1%, and combined with the anodizing treatment of the whole machine, it has excellent wear resistance and corrosion resistance. In laboratory simulation tests, after 100,000 cycles of wear, the wear amount is only 0.05mm, while that of ordinary components reaches 0.2mm. It can withstand long-term frequent use and the test of harsh environments, prolonging the service life and reducing the replacement frequency.

Excellent Reliability
It can work stably under various working conditions (such as temperature fluctuations, humidity changes, etc.). An optional integrated temperature sensor (needs to be matched with the CLAAS CEBIS system) can monitor the camshaft temperature in real-time, and automatically alarm when the abnormal temperature rise exceeds 15℃ to avoid faults in advance. The modular design allows for replacement by a single person within 30 minutes. Combined with the global spare parts network of CLAAS, the average spare parts delivery cycle in the Chinese market is ≤3 working days, reducing downtime caused by component failures and ensuring the continuity of agricultural production.

Improving Overall Efficiency
Through stable performance, long service life, and efficient operation, it indirectly reduces equipment maintenance costs and downtime losses. The low-friction design reduces the overall fuel consumption by about 8%. Based on 2000 working hours per year, it can save about 12,000 yuan in diesel costs annually (based on China's diesel price of 7 yuan per liter). At the same time, for example, a farm in Heilongjiang used this component in the JAGUAR 870 silage harvester and did not replace similar components for three consecutive operating seasons, with the failure rate reduced by 70% compared to the old model, bringing higher economic benefits to users.
