K Series Helical-Bevel Gearbox
High Torque · Low Noise · 100% Load Tested
Product Overview
K‑series is right‑angle 90‑degree helical‑bevel gear unit with high‑rigidity cast‑iron housing. Built on modular system, it supports foot, flange and shaft‑mount installation, solid/hollow output shaft. Hardened alloy steel gears are carburized‑quenched and precision‑ground for high load capacity, low noise and over 90% efficiency. 2‑stage or 3‑stage gearing, low‑backlash option available. Widely applied in metallurgy, mining, chemical, paper‑making and construction machinery.
