647431.0 Silent Block Rubber Bushing

Applications in Agricultural Machinery

• Suspension System

  Silent Block Rubber Bushing is used in the suspension mechanism of agricultural tractors and other farming machines such as harvesters and seeders. It connects the chassis with the suspension arm or the suspension arm with the farm implement, providing cushioning and shock absorption.

• Power Transmission System

  The connecting shafts between the engine and gearbox, gearbox and driving axle, and driving axle and wheel hub may use rubber bushings to reduce vibration during power transfer.

• Operating Mechanism

  Silent Block Rubber Bushing is also used in steering linkages, brake systems, and hydraulic operating mechanisms to reduce impact and vibration.

• Work Device Connection Points

  Various work components of agricultural machinery, such as plows, harrows, and cutters, are connected to the mainframe with rubber cushioning to reduce impact and ensure work quality.

Signs of Replacement

• Abnormal Vibration and Noise

  When the rubber bushing becomes ineffective, the vibration that was supposed to be absorbed by it will be transferred to the entire machinery structure, resulting in noise such as "crackling" or "clang".

• Decreased Precision

  If the operation precision of the farm machinery is lower than before, such as unstable steering or difficulty in maintaining straight-line travel, it may be due to the loss of cushioning and shock absorption in the suspension system or work device connection points.

• Obvious Wear and Tear

  If cracks, fractures, severe wear, deformation, or complete breakage are found on the surface of the rubber bushing during regular inspection of the machinery, the bushing has lost its function and must be replaced.

• Decreased Performance

  If the farm machinery feels more bumpy during travel, or the implement's contact with the soil becomes worse during operation, it may be due to the ineffectiveness of the Silent Block Rubber Bushing in the suspension system or work device connection points.

Selecting the Right Silent Block Rubber Bushing

• Inner and Outer Diameter Size

  Accurately measure the inner and outer diameter and length of the original bushing to ensure that the new bushing fits snugly into the installation position.

• Installation Method

  Pay attention to the design of the bushing, including whether it has threads, flanges, or other special installation structures.

• Material

  High-quality rubber bushings are usually made of fatigue-resistant and wear-resistant synthetic rubber, such as NBR, HNBR, FKM, etc., depending on the specific working conditions.

• Damping Requirements

  Select rubber materials with suitable damping characteristics according to the vibration characteristics of the farm machinery to effectively absorb vibration energy.

• Weatheability

  If the farm machinery operates outdoors for a long time, the bushing must have good UV resistance, ozone resistance, oil resistance, and chemical resistance.
