HR Series Helical Inline Gearbox Design: Helical gears offer
higher transmission efficiency and lower noise compared to spur gears, making
them suitable for high-speed, heavy-duty application scenarios.
Compact structure: HR Series Helical Inline Gearbox are
usually compactly designed to save installation space, suitable for
space-constrained applications.
High Rigidity: HR Series Helical Inline Gearbox are made of
high-strength materials with high rigidity and durability, capable of
withstanding large radial and axial loads.
