ISO 7 Grade Spur Gears for Heavy-Duty Applications - 500 lb-ft Torque Capacity, 58-62 HRC Hardness

Spur gears are specifically designed for low-speed, heavy-duty applications where large loads must be transmitted efficiently. Through increased tooth width and modulus, these gears provide superior load-bearing capacity and rigid tooth structure ideal for high-torque transmission.

• High root strength with vertical tooth distribution reduces stress concentration and withstands large bending loads
• Controlled meshing impact at low speeds ensures high transmission reliability
• Increased tooth width expands contact area for enhanced load-bearing capacity
• ISO 6-7 accuracy grade precision manufacturing
• Surface hardness of 58-62 HRC through carburizing heat treatment

At low speeds, the extended time interval between gear tooth meshing effectively disperses instantaneous loads. The robust tooth surface strength resists extrusion deformation, ensuring stable torque transmission under demanding conditions.

• Steel rolling mill auxiliary transmission devices
• Large gate opening and closing mechanisms
• Mine crusher reduction gears
• Heavy machinery requiring reliable low-speed power transmission
