FAQ
What is "Easy Break" technology?
It is a design feature that allows the chain to be cut to length quickly and easily without damaging the structural integrity of the links.
How does EXL compare to standard carbon steel chains?
EXL provides higher fatigue strength due to its wide-waist plate design and optimized press fits between the pin and plate.
What is the temperature range for EXL lubrication?
The standard DH-2 premium lubrication is designed to operate between -5°C and +100°C.
Is the EXL series pre-loaded?
Yes, all EXL chains are pre-loaded at 40% to 50% of the breaking load during manufacturing to ensure immediate stability upon installation.
Are custom lubricants available?
Yes, alternative lubricants for special applications can be provided upon request. Contact Corsair Sarl today to find out more.
