42JBK30K 42mm High Precision Planetary Small Backlash Gearbox

The 42JBK30K 42mm High Precision Small Backlash Planetary Gearbox is a high-performance product specifically designed for applications requiring high precision. This gearbox features small backlash and high transmission efficiency, making it ideal for scenarios that demand precise control and high torque output. With a maximum permissible radial load of 50N and a maximum shaft axial load of 15N, it ensures stable operation under various complex conditions. The radial play of the shaft is less than 0.08mm, and the axial play is less than 0.4mm, with a backlash at no-load of less than 0.5°, guaranteeing outstanding performance in high-precision requirements. Additionally, the output shaft of this gearbox uses rolling bearing ball bearings, with a maximum shaft press fit force of 100N, further enhancing its durability and reliability. The operating temperature range is from -10°C to +80°C, and the operating ambient humidity is between 20% and 85%RH, adapting to various environmental conditions. The recommended input speed does not exceed 3000rpm, ensuring efficient operation and long service life of the gearbox.
