PLW High-Strength Corrosion-Resistant Bush Chains for Industrial Machinery Use

Structural Composition

• Inner and outer link plates: Form the two sides of the chain and provide structural strength.

• Bushings: Cylindrical components installed between the inner link plates, allowing the pins to rotate smoothly.

• Pins: Pass through the bushings to connect the inner and outer link plates.

• Rollers (optional): Some bushing chains are equipped with rollers, which can reduce friction when meshing with sprockets.

Types

• Rollerless bushing chains: Composed only of bushings and pins, they have a simple structure and are suitable for scenarios where rollers are prone to wear or conveyed materials may damage the rollers.

• Type S bushing chains: Equipped with rollers whose diameter is smaller than the width of the link plates. They can enhance the protection of sprocket teeth and bushings, extending the service life.

• Type P bushing chains: Adopt rollers with a diameter larger than the width of the link plates, improving rolling efficiency and reducing wear on the chain and conveyor track.

• Type F bushing chains: Rollers have flanges on both sides, which can guide the chain to run along the conveying path and prevent lateral displacement.

Characteristics

• Advantages: Compared with roller chains, bushing chains have a simpler structure, lower manufacturing costs, and a weight reduction of approximately 40%. Meanwhile, they operate with low noise, can work without lubrication, and have good tolerance to contaminated environments.

• Disadvantages: Their maximum working load is usually less than 1100 pounds. Without load-bearing rollers, they are prone to rapid stretching and wear; imprecise meshing can cause vibration, making them unsuitable for high-speed or impact load scenarios.

Application Fields

• Mining industry: Used for transporting heavy materials.

• Agricultural field: Can convey agricultural crops.

• Automotive industry: Play a role in assembly lines.

• Cement and steel plants: Used for handling raw materials and finished products.

Common Series

• FV Series: Available in various specifications such as FV40 and FV63, suitable for multiple industrial scenarios.

• FVT Series: Includes models like FVT40 and FVT63 to meet different user needs.

• M Series: Common specifications include M80 and M112, featuring a robust structure and reliable performance.
