Advanced Equipments

Qingdao Choho has worldclass production and manufacturing equipments such as high-speed punching machine, continuous heat treatment mesh belt furnace, highprecision wire cutting machine, coordinate grinder,shot blasting machine, high-speed pipe pin cutting machine, automatic chain assembly line and ultrasonic automatic cleaning and hot dipping line, etc., which form a professional large-scale, high-quality and stable production mode.

With conventional testing instruments such as metallographic, laboratory, chain length, tensile strength, hardness, spark, twist, press-out force and other performance testing equipments such as wear-resistant experiment and high-speed fatigue testing machine, we make every chain and chain parts undergo rigorous quality testing to ensure that every chain we sell is of reliable and excellent quality.

O/X Ring

▲ The lubricating oil of ordinary chains is easy to overflow

Wear test comparison
▲ How O ring seals the outlet of ubrication oil

▲ How X ring seals the outlet of ubrication oil

▲ How ☆ ring seals the outlet of ubrication oil

a Treated Pin

▲ Anti-wearing ▲ Anti-high tempreture ▲ Anti-corruption

Solid Bush

▲ Achieve complete contact between the pin and the bush.

High Adhesion Grease

▲ Racing grade white grease, high adhesion, wear resistancenoise reduction,high temperature resistance, suitable forhigh speed movement over 250km/h.

Vacuum Oiling

▲ Through the vacuum pump, each aperture of parts is filled with wear-resistant grease and the chain life is extended by 30%.

CrV Treatment And C-n Treatment Wear Resistance Comparison

Chain Advantages

CrV Treatment Technology

The traditional chain treatment process for the pin shaft adopts the traditional C-N treatment, and the CrV treatment technology and the strengthened pre-tensioning technology of the chain are used to enhance the surface strength of the pin shaft and the fatigue strength of the chain, which greatly improves the durability of the chain.

This technology is mainly used in the surface strengthening treatment of the pin shaft, which can make the surface hardness of the pin shaft reach 2200HV, and can improve the wear resistance of the chain by more than 100%

S25H Solid Bush

Traditional chains mostly use rolled sleeves, S25H introduces cold forging technology, seamless sleeves greatly improve the wear resistance of the chain

Timing Chain

CHOHO provides three types of timing chains: Strengthen Silent Chain, Silent Chain, Bush Chain. Strengthen Silent Chain has a world-top-level performance through applying special material and technology. All these timing chains are using special chromizing heat treatment and 35CrMo steel, bringing 10-20% improvement on tensile strength and 20-90% improvement on wearing performance.

Fine Blanking Sprocket

Fine Blanking is a kind of technology, with special-structured precision mould and customized fine blanking press machine, to realize small clearance precision punching, making the materials under three to compressive stress state with strong pressure.

▲ The perfect tooth profile design makes the chain and sprockets in perfect engagement stable driving, and low noise.

▲ High-precision dimension, small geometric tolerance, can guarantee the sprockets installation accuracy and easier to install.

▲ The minimum pitch divergence ensures the consistency between chain and sprockets and chain is not easy to jump.

Light weight Sprocket

Aluminum Alloy Sprocket

High quality high strength aerospace aluminum alloy CNC machining the light-weighting holes, a variety of patterns, style switching is quick and convenient, to meet individual customization needs.

The surface treatment uses an anodizing process, and the colors are varied to meet different individual needs.

The surface treatment uses a hard oxidation process, which improves the wear resistance and tensile strength of the conventional oxidation process. Light weight36% of steel sprocket.
