Spur gears have straight teeth for efficient, cost-effective power transmission in conveyors, appliances, automotive gearboxes, and robotics. Their simple design reduces backlash, making them ideal for high-speed, moderate-load systems needing precise timing. Available in various sizes and materials, they suit custom gear ratios and compact setups.
