Frequently Asked Questions
What surface hardening processes do you apply?
Induction hardening (tooth-by-tooth), gas nitriding, and case carburizing to 0.8–1.2 mm effective case depth. Rockwell hardness is verified on every batch.
What load ratings can your pulleys handle?
Rated per ISO 6336 for tooth root bending and surface durability. Typical ratings exceed 2,500 N·m continuous torque for 20 mm pitch with proper belt tension.
Do you offer wear-resistant coatings?
Yes — DLC (diamond-like carbon), TiN (titanium nitride), and electroless nickel plating. DLC can extend tooth life by 3–5× in dry-running applications.
How do I select the right hardening depth?
Our engineering team evaluates your torque, speed, and duty cycle. General guideline: 0.8 mm case depth for moderate loads, 1.2+ mm for impact-loaded mining or construction drives.
