Our Chain Coupling Advantages
- High torque in compact size – Roller chain system transmits more torque per diameter than many other coupling types.
- Misalignment tolerance – Double-strand chain connection handles small angular and parallel misalignments between connected shafts.
- Versatile design – Standard roller chain and sprocket components make replacement parts readily available.
- Simple assembly & disassembly – Connecting link allows fast installation without moving shafts.
- Durable & reliable – Hardened steel sprockets and precision Rexton® roller chain ensure long service life.
Typical Applications
- Heavy-duty conveyors, crushers, and mixers
- Gearboxes and industrial drives
- Machinery in dusty, rugged, or outdoor environments
- Low speed, high torque drives, where space is limited
Selection Guide (Quick Steps)
- Determine operating power and speed– Based on motor power (kW or HP) and rpm.
- Select coupling size – Choose a model with rated power ≥ design power.
- Check shaft compatibility – Ensure shaft diameter and keyway match the coupling bore. If not, select the next size up.
- Confirm lubrication requirement – Depending on operating conditions, lubricate weekly, monthly, or fill cover with grease.
- Consider operating conditions – Lubricated enclosed covers recommended for dusty or wet conditions.
Installation & Maintenance Tips
- Align shafts within allowable tolerances before fitting the chain.
- Apply grease inside the cover, re-lubricate periodically for best performance.
- Inspect chain and sprockets periodically; replace at signs of wear or elongation.
FAQ
Do chain couplings require lubrication?
Yes. Proper lubrication minimizes wear and ensures long service life. Re-apply grease periodically to minimize wear.
How much misalignment can it handle?
The double-strand chain connection allows for small angular and parallel deviations; accurate alignment is still recommended.
When should the coupling parts be replaced?
Replace chain if elongated or stiff links are visible. Replace coupling if sprocket wear is observed.
Can i use a standard roller chain for replacement?
Our chain couplings utilise Rexton® roller chains that are built to standard ANSI double strand dimensions. For best results, use Rexton replacement chains manufactured to precise tolerance and hardness standards.
