Rokee® Customized GL Roller Chain Coupling for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
The GL roller chain coupling consists of a double row roller chain and a pair of chain wheels with shaft sleeves. The main material is 45 # steel, which has undergone high-frequency quenching treatment to improve wear resistance.
Compact structure: Only four components are needed to complete assembly, and there is no need to move the connecting shaft during disassembly, making maintenance convenient.
High adaptability: allows axial, radial, and angular deviations (≤ 1 °), suitable for scenarios with low installation accuracy requirements.
Environmental tolerance: It can operate stably in humid and dusty environments ranging from -40 ℃ to 120 ℃, commonly found in heavy industries such as mining, metallurgy, and papermaking.
Key performance indicators:
Speed limit: usually not exceeding 4000 rpm.
Protective design: Standard metal casing (aluminum or steel) to prevent chain detachment and extend lubrication cycle.
Materials and processes:
The sprocket teeth undergo high-frequency quenching, with a hardness of HRC45-50, significantly improving their wear resistance.
The double row chain structure enhances the stability of torque transmission and extends the lifespan of a single row chain by more than 30%.
Installation precautions:
The deviation of the two axis alignment should be controlled within 0.1mm to avoid chain wear.
Lubricating grease (such as lithium based grease) should be added before the first operation, and then replenished every 500 hours thereafter.
Industry Applications
Mining Machinery: GL roller chain couplings are used in belt conveyor drive systems to withstand dust and impact loads.
Chemical equipment: GL roller chain couplings made of stainless steel material perform well in acidic and alkaline environments, such as agitator drives.
