87665855 Silent Block Rubber Bushing

Silent Block Rubber Bushing is a type of rubber bushing that is commonly used in agricultural machinery. It is used to connect the chassis with the suspension arm, or the suspension arm with the agricultural tool, and helps to reduce shock and vibration.Here is a table of the different brands and models of agricultural machinery that can use the 87665855 Silent Block Rubber Bushing:[ninja_tables id="409883"]Silent Block Rubber Bushing is generally used in the following parts of agricultural machinery:

Suspension System

Silent Block Rubber Bushing is used in the suspension system of agricultural tractors and other farming equipment such as combines and seeders. It connects the chassis with the suspension arm or the suspension arm with the agricultural tool, and reduces shock and vibration.

Power Transmission System

Silent Block Rubber Bushing is used to connect the engine with the gearbox, the gearbox with the drive shaft, and the drive shaft with the wheel hub. It helps to reduce the vibration during the power transmission process.

Control Mechanism

Silent Block Rubber Bushing is used in the steering linkage, brake system, and hydraulic control mechanism to reduce shock and vibration.

Work Device Connection Point

Silent Block Rubber Bushing is used to connect various agricultural work components such as plows, harrows, and cutting platforms to the main frame of the agricultural machinery. It helps to adapt to the working conditions of uneven terrain and reduce the impact on the main structure.Here is a picture of a Silent Block Rubber Bushing:There are several signs that indicate the need to replace the Silent Block Rubber Bushing:

Abnormal Vibration and Noise

When the rubber bushing fails, the vibration that it previously absorbed will be transferred to the entire machinery structure, resulting in noise such as "click" or "clang".

Decreased Precision

If the precision of the agricultural machinery operation decreases, such as unstable steering or difficulty maintaining a straight line during field work, it may be due to the wear of the rubber bushing in the suspension system or the work device connection point, causing component displacement.

Obvious Signs of Wear

During the regular inspection of the agricultural machinery, if there are cracks, severe wear, deformation, or complete breakage on the rubber bushing surface, it indicates that the bushing has lost its function and must be replaced.

Decline in Driving or Operating Performance

If the agricultural machinery feels more bumpy during driving, or the agricultural tool has a poor fit with the soil during work, it may be due to the failure of the Silent Block Rubber Bushing affecting the normal operation of the suspension system or the work device.Here is a picture of how the worn-out Silent Block Rubber Bushing looks like:When choosing the appropriate Silent Block Rubber Bushing, there are several factors to consider:

Inner and Outer Diameter Size

Exact measurement of the original bushing's inner and outer diameter and length is necessary to ensure that the new bushing can fit the installation position tightly.

Installation Method

Pay attention to the bushing's design, including whether it comes with threads, flanges, or other special installation structures.

Material

High-quality Silent Block Rubber Bushing is usually made of synthetic rubber that is fatigue-resistant and wear-resistant, such as NBR, HNBR, FKM, etc., depending on the specific working conditions.

Damping Requirements

According to the vibration characteristics of the agricultural machinery, select rubber materials with appropriate damping characteristics to effectively absorb vibration energy.

Weatherability

If the agricultural machinery works outdoors for an extended period, the bushing needs to have good resistance to ultraviolet radiation, ozone, oil, and chemical corrosion.Author: Miya
