In the world of professional saw milling and timber processing, precision and power are non-negotiable. Qirui’s long chainsaw bars, engineered from solid pro-grade materials and precision-machined for accuracy, meet the high torque and intense load demands of hardwood cutting and oversized log handling.
Designed specifically for Alaskan mill systems, portable sawmills, and industrial timber mills, Qirui bars help forestry professionals reduce waste and increase yield — with fewer replacements and less downtime.
Whether you’re trimming short logs or ripping entire tree trunks for lumber, Qirui offers the most versatile size range in the market:
Bar Length | Application Scope |
---|---|
6"–24" | General cutting, garden & trimming use |
25"–48" | Professional-grade forestry & field milling |
49"–76" | Alaskan mill setups, slab cutting, large hardwood |
For OEM/ODM clients, custom lengths and widths can be designed based on your machine’s technical drawings or sample specifications.
Qirui’s heavy-duty bars are manufactured with heat-treated alloy steel and undergo CNC laser profiling, followed by precision machining to ensure:
Flat, even surfaces for consistent cutting
Extreme torsional strength for high RPM motors
Anti-bending and anti-fracture properties
Resistance to friction, overheating, and wear
Each guide bar is reinforced at stress points, including the nose and rails, to handle continuous duty cycles in commercial milling environments.
Our long chainsaw bars are designed to fit most professional chainsaw platforms used in forestry, construction, and portable sawmills, including:
Stihl
Husqvarna
Echo
Jonsered
Makita
Dolmar
Qirui also offers adapters and mount customization for integration into Alaskan-style sawmill rigs and slab-milling setups.
