Professional Applications & Engineering Value
This ACME lead screw is engineered from Grade 2 carbon steel with a zinc-plated finish to address common industrial challenges like corrosion, high load demands, and precision control requirements. The fully threaded design with right-hand direction and ACME thread type provides excellent torque transmission and backlash resistance, making it ideal for CNC machinery, linear actuators, and positioning systems. Its Rockwell B61 hardness ensures durability against wear, while the standardized 1"-5 thread size and 12" length facilitate easy integration into existing motion control setups, reducing downtime and maintenance costs in automation, packaging, and material handling equipment.
Specification Summary & Compliance
This lead screw adheres to critical specifications including a Class 2G thread fit for dimensional accuracy, ASTM A108 material standards, and RoHS 3 (2015/863/EU) compliance for environmental safety. The threading conforms to ACME standards with a right-hand direction and fully threaded configuration, ensuring reliable performance in linear motion applications.
