Short Pitch Precision Roller Chain (A Series)

Short Pitch Precision Roller Chain  (A  Series) 

The standard short pitch single-row roller chain is a type of chain commonly used in transmission machinery, and the following is a detailed introduction to it:

Basic concepts

Name: Standard short pitch single row roller chain, often referred to simply as single row roller chain or short pitch roller chain.

Definition: A short pitch roller chain is a roller chain in which the ratio of the basic pitch to the outer diameter of the roller is less than 2, and the outer diameter of the roller is less than the height of the chain plate. Among them, "standard" usually refers to the specifications and dimensions that comply with relevant international or domestic standards.

Application: It is widely used in various machinery in various industries such as agriculture, mining, metallurgy, petrochemical industry and lifting and transportation, and is used for occasions with small transmission power.

Structure and composition

Main components: The standard short pitch single-row roller chain is composed of an inner plate, an outer plate, a pin, a sleeve and rollers. The inner plate and the sleeve, the outer plate and the pin are interference fits; The roller and the sleeve, and the sleeve and the pin are all clearance fits.

Material: Each part of the chain is usually made of carbon steel or alloy steel, which is heat treated to achieve a certain strength and hardness.

Features & Benefits:

High transmission efficiency: Compared with belt transmission, roller chain transmission has no elastic sliding, can maintain an accurate average transmission ratio, and has higher transmission efficiency.

Strong bearing capacity: roller chains can be made into multi-row chains, and multi-row chains can be used when it is necessary to bear large loads and transmit large power.

Adaptability: According to different working environments and needs, roller chains with different materials and different surface treatments can be selected, such as zinc plating, nickel plating, chrome plating and Dacromet treatment.

Reliable work: the roller chain drive will not slip, the transmission is reliable, the overload capacity is strong, and it can work well under low speed and heavy load.

Use & Maintenance

Installation: When installing the roller chain, make sure that the tight edge of the chain is on the top and the loose edge is on the bottom to facilitate lubrication and reduce wear. At the same time, attention should be paid to the joint treatment of the chain to ensure that the joint is firm and reliable.

Lubrication: Regular lubrication is key to keeping your roller chains in good working order. According to the use of the chain and the working environment, the appropriate lubricant should be selected for lubrication.

Inspection and maintenance: Regularly check the wear, tightness and firmness of the chain, find problems in time and deal with them. For the chain with serious wear, it should be replaced in time to avoid safety accidents.

To sum up, the standard short pitch single-row roller chain is a transmission chain with the advantages of high strength, high transmission efficiency, strong bearing capacity and strong adaptability. During use, attention should be paid to installation, lubrication and inspection
