GL Type Roller Chain Coupling
Certs: ISO9001:2015, ROHS and REACH205 Compliant, Emvironmental friendly protection testing
Application:General industrial equipment, agricultural and food machinery, building materials, mining machinery, and other low-speed, heavy-duty applications.
GL Type Roller Chain Coupling
Product Introduction:Similar in structure and principle to the GL Type Roller Chain Coupling. For the same model, the shaft hub length varies according to the bore size.
Main Materials:Shaft hub: 45# steel; Housing: Cast aluminum
Application Scenarios:General industrial equipment, agricultural and food machinery, building materials, mining machinery, and other low-speed, heavy-duty applications.
Note:The standard main material is 45# steel. If other materials (such as stainless steel) are required, please communicate with our sales staff when placing the order. For special technical processing requirements, technical parameters need to be confirmed.

FAQS:
1. What is a GL Type roller chain coupling?
The GL Type roller chain coupling is a flexible coupling used to connect two rotating shafts. It consists of two hardened steel sprockets and a double-strand roller chain. It allows for minor misalignments and is ideal for power transmission in industrial machinery.
2. What materials are used for GL series couplings?
The sprockets are made of C45 carbon steel with hardened and heat‑treated teeth (HRC40 hardness). The cover (on GLF type) is typically Zamak or cast steel. The roller chain conforms to ISO/R606 or ANSI standards.
3. What is the difference between GL and GLF types?
GL Type is the basic model without a cover. GLF Type includes a protective cover that keeps out dust, dirt, and moisture while preventing lubricant spillage. Both types offer the same torque capacity and sprocket dimensions.
4. How do I choose the correct GL coupling size?
Selection depends on your shaft diameter, required torque, and operating speed. GL sizes range from GL1 to GL13, with bore diameters from 16 mm to 190 mm. Always compare your application's peak torque with the coupling's rated torque using the manufacturer's selection table.
5. Can the coupling be removed without moving the connected machines?
Yes. One major advantage of the roller chain coupling is that you can detach the chain and slide the sprockets off the shafts without moving the motor or driven equipment. This simplifies maintenance and replacement significantly.
6. What maintenance does a GL chain coupling need?
Maintenance is simple: lubricate the chain regularly with grease or oil (depending on speed and environment), and check for chain wear or elongation. Replace the chain when elongation exceeds 3%, and inspect sprocket teeth for wear during routine shutdowns.
7. Is the GL coupling suitable for harsh environments like dust or high heat?
Yes. The GL coupling performs well in dusty, humid, and high‑temperature conditions, especially when using the GLF cover. The heat‑treated teeth resist wear, and high‑temperature grease can be used for the chain. For extreme cases, consider stainless steel or sealed versions.
