A gear rack or steel rack can keep your machinery on track. When used with spur gears, gear racks use rotary motion to create linear motion or transmission. These types of gear drives create rack and pinion motion that is typically used in automotive steering configurations. The gear pitch is the area where both gears (spur gear and rack gear) connect with each other to create torque. At Zoro, we also have the gearmotor accessories you need to keep all your gear racks in tip-top shape.
