Product Description

GW211PPB4 W211PPB5 W211PPB6 Agricultural Machinery Bearing Farm Bearing

Agricultural machinery bearings are an important part of contemporary machinery and equipment. Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into rolling bearings and sliding bearings.

Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial size, vibration and noise are larger, and the price is also higher. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling elements and cage. Strictly speaking, they are composed of six parts: outer ring, inner ring, rolling element, cage, seal, and lubricant. Mainly equipped with outer ring, inner ring, and rolling element can be defined as a rolling bearing. According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings.

FAQ1: Why do farm machines use square holes instead of round ones?

a. No Slipping: A round axle can sometimes slip or spin inside a round bearing under heavy pressure. A square axle in a square hole cannot slip. It locks the axle and bearing together to turn as one.
b. High Torque: It allows the machine to transmit massive amounts of rotational force (torque) to turn heavy disc blades through thick mud and clay.

FAQ2: What are the characteristics and advantages of specialized agricultural bearings used in disc harrows?

Disc harrows work directly in the soil to break up dirt. Because of this, disc harrow bearings must be incredibly tough and perform well:
a. High Impact Resistance: They must survive hitting rocks and hard roots constantly.
b. Extreme Sealing: Dust is the natural enemy of bearings. Bearings of this type require a multi-lip seal design (typically a triple-lip or “three-layer” seal) to prevent contaminants from entering and abrading the steel balls, which would impair the bearing’s performance.
c. Heavy Loads: They hold up the total weight of the heavy metal disc gang
