Specification Brand : HARFINGTON BulletPoint1 : Size - Model: 1.5 Mod; Length: 500mm/19.69"; Width: 15mm/0.59"; Height: 15mm/0.59"; Tooth Pitch: 4.71mm/0.19"; Tooth Depth: 3.38mm/0.13" BulletPoint2 : Material - The spur rack is made of 45# steel, which has high hardness, strength, and strong deformation resistance, it is more durable, longer lasting, and easier to process, install, and debug. BulletPoint3 : Feature - Racks are used to convert rotary motion into linear motion. The straight teeth of the rack are cut into one face of the square or circular section of the rod and fit with the pinion, which has the characteristics of mechanical simplicity, high load-carrying capacity, and unlimited length. BulletPoint4 : Application - Spur racks are paired with spur gears and are suitable for lifting mechanisms (vertical movement), horizontal movement, positioning mechanisms, stopping and allowing simultaneous rotation of multiple axes in industrial machinery. BulletPoint5 : Note - Only gears of the same type can be used with racks. For example, a 1M rack can be used with all 1M gears.

Usually, the teeth are straight (spur rack). Rack and pinion are sometimes used instead of an trapezoidal threaded shaft and nut to move a machine head in a back and forth motion. The spur rack is made of 45# steel, which has high hardness, strength, and strong deformation resistance, it is more durable, longer lasting, and easier to process, install, and debug. Racks are used to convert rotary motion into linear motion. The straight teeth of the rack are cut into one face of the square or circular section of the rod and fit with the pinion, which has the characteristics of mechanical simplicity, high load-carrying capacity, and unlimited length. Spur racks are paired with spur gears and are suitable for lifting mechanisms (vertical movement), horizontal movement, positioning mechanisms, stopping and allowing simultaneous rotation of multiple axes in industrial machinery. Notice: Only gears of the same type can be used with racks. For example, a 1M rack can be used with all 1M gears.
