KC/GL Roller Chain Coupling with Guard – 45# Forged Steel, Case-Hardened, High Torque

Factory direct | 45# forged steel | Case-hardened teeth | H7 bore | 190 N·m torque | 5000 RPM | Protective guard included | Easy assembly without moving shafts | OEM custom

The Apexcoupling KC/GL series is a roller chain coupling designed for reliable power transmission in general motor applications. Featuring a robust 45# forged steel construction with case-hardened (high-frequency quenched) teeth, this coupling delivers high torque capacity, excellent wear resistance, and long service life. The included protective guard ensures safety and contamination protection. With a simple four-component design, it allows for easy installation and disassembly without moving connected shafts – significantly reducing maintenance downtime.

✅ Ideal for textile, agricultural, lifting, transport, engineering, mining, light industry, and chemical machinery.

Why Choose Apex Coupling for KC/GL Chain Couplings?

FAQ

Q: What is a roller chain coupling?
A: A roller chain coupling consists of two sprockets connected by a roller chain. It transmits torque while accommodating small misalignments between shafts .

Q: What is the difference between KC and GL series?
A: Both are roller chain couplings with similar designs. KC and GL are common model designations with minor dimensional differences. GL series generally covers a wider torque range (up to 25,000 N·m) .

Q: What material is used?
A: The sprockets are made of 45# forged steel with case-hardened (high-frequency quenched) teeth for extended wear life .

Q: Does the coupling come with a guard?
A: Yes. Every KC/GL coupling includes a protective guard for safety, dust protection, and lubrication retention.

Q: Can I disassemble the coupling without moving the motor or load?
A: Yes. The simple four-component design allows you to remove the chain and guard without shifting the connected shafts .

Q: What is the service life compared to standard couplings?
A: Thanks to case-hardened teeth and a thicker tooth profile, our KC/GL series offers 30% longer life than standard designs.

Q: What torque range is available?
A: KC series covers up to 930 N·m for KC 5018; GL series covers up to 25,000 N·m for GL15 . The rated torque of 190 N·m is for typical mid-range models.

Q: Can I get a custom coupling?
A: Yes. We offer OEM customization – custom bores, chain specifications, and guard designs available.
