Due to the large spherical contact area and strong multi-angle swinging ability of spherical plain bearings.It has strong load-bearing capacity and good movement flexibility, and is applied in multiple industries such as engineering hydraulic cylinders, forging and pressing machines, and automated equipment.
Description:The threaded assembly rod end spherical plain bearing mainly consists of the rod end body (housing) with threads, the inner ring with ball surface, the rolling elements (steel balls, etc.) and the cage (in some structures). The rod end body is connected to other mechanical components through threads. The inner ring fits with the shaft and other parts. The rolling elements roll between the inner ring and the spherical raceway of the rod end body.

Five Core Technical Advantages
Full-process Heat Treatment Strengthening ProcessUsing GCr15 high-carbon chromium bearing steel as the base material, after dual treatment of 1080℃ high-temperature quenching and 180℃ tempering, a surface hardened layer (depth 0.8-1.2mm) is formed, with a hardness of HRC60-62. The wear resistance is 40% higher than ordinary bearings, calmly coping with abrasive impacts such as soil particles and straw fibers.
01
Micron-level Precision Control SystemUsing CNC five-axis grinding machines for raceway forming (roundness error ≤0.0008mm), combined with dynamic calibration by laser vibrometers, to ensure the bearing radial runout ≤0.002mm. It suppresses mechanical vibration from the source, reduces operating noise by over 15%, and guarantees the execution accuracy of precise actions such as seeding and harvesting.
02
Adaptive Load Structural DesignUnique double-row tapered roller arrangement can withstand radial loads (8-50kN) and axial loads (10-60kN) simultaneously. Combined with a floating aligning structure (aligning angle ±2.5°), it effectively absorbs dynamic impacts caused by uneven farmland, extending component life by 30%.
03
Three-dimensional Anti-corrosion Protection SchemeThe surface treatment uses a three-layer protection of "galvanized base + nanoceramic coating + epoxy resin sealing layer". The salt spray test time is ≥1000 hours, which can resist long-term erosion by fertilizer solutions (pH 3-11) and pesticides, and maintain smooth operation in high-humidity environments with a moisture content of over 85%.
04
Smart Lubrication System AdaptationReserved oil injection channels and oil storage tank structures are compatible with automatic lubrication devices, supporting low-temperature start at -20℃ and continuous operation at 120℃ high temperature. They meet the needs of 24/7 continuous operation and reduce manual maintenance frequency by 50%.
05
Multiple Application Scenarios
Suitable for three core agricultural machinery systems:
Steering System (Tractors/Combine Harvesters): Achieves ±45° flexible steering, reduces steering resistance by 18%, and improves field turning efficiency.
Suspension System (Seeders/Transplanters): Dynamically balances loads, ensuring seeding depth error ≤ ±2mm and transplanter verticality ≥ 98%.
Transmission System (Rotary Tillers/Dryers): The **Ball Head Hinge for Spray Boom** efficiently transmits power, reducing transmission loss by 12%. It ensures uniform tillage depth and enhances dryer stability, delivering reliable performance for agricultural machinery.
Special Scenario Adaptation:
Flexible arm connection for fruit and vegetable picking machinery
Folding mechanism transmission for plant protection drones
Lifting system support for livestock machinery
