84459072 Silent Block Rubber Bushing

Silent Block Rubber Bushing is a type of rubber bushing that is used in agricultural machinery to dampen vibrations and reduce shock. It is commonly found in the suspension system, power transmission system, steering mechanism, and working device connection points of agricultural equipment.

Applications of Silent Block Rubber Bushing

Suspension System

Silent Block Rubber Bushing is used to connect the chassis with the suspension arm or the implement with the suspension arm in agricultural tractors and other farm machinery, such as combine harvesters and seed drills. It plays a role in buffering and shock absorption.

Power Transmission System

Silent Block Rubber Bushing is used in the connection shafts between the engine and the gearbox, the gearbox and the drive axle, and the drive axle and the wheel hub. It reduces the transmission of vibrations during power transmission.

Steering Mechanism

Silent Block Rubber Bushing is also used in the steering linkage, braking system, and hydraulic control mechanism to reduce the impact and vibration of moving parts.

Working Device Connection Points

Silent Block Rubber Bushing is used to connect various working components, such as plowshares, rake blades, and cutterbars, with the mainframe of agricultural machinery. It reduces the impact on the main structure and adapts to uneven working conditions.

Signs You Need to Replace Silent Block Rubber Bushing

Abnormal Vibration and Noise

When the rubber bushing fails, the vibration that it should have absorbed will be transmitted to the entire machinery structure, causing noise such as "clicking" or "clanging".

Decreased Precision

If the operating precision of the agricultural machinery decreases, such as unstable steering or difficulty in maintaining straight-line travel during field operation, it may be due to the wear of the rubber bushing at the suspension system or working device connection points, which causes the component's position to shift.

Obvious Signs of Wear and Tear

When checking the various parts of the agricultural machinery regularly, if you find that the rubber bushing surface has cracks, fractures, severe wear, deformation, or even complete rupture, it means that the bushing has lost its function and must be replaced.

Decreased Driving or Operating Performance

If the agricultural machinery feels more bumpy during operation or the implement's fit to the soil deteriorates, it may be due to the failure of the rubber bushing, which affects the proper functioning of the suspension system or working device.

How to Choose the Right Silent Block Rubber Bushing

Inner and Outer Diameter

Accurately measure the inner and outer diameters as well as the length of the original bushing to ensure that the new one can fit tightly in 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 nitrile rubber (NBR), hydrogenated nitrile rubber (HNBR), fluoro rubber (FKM), etc. Choose the appropriate material based on the specific conditions.

Damping Requirements

Select a rubber material that has suitable damping characteristics according to the vibration characteristics of the agricultural machinery to effectively absorb the vibration energy.

Weather Resistance

If the agricultural machinery works outdoors for a long time, the bushing should have good resistance to UV radiation, ozone, grease, and chemical corrosion.
