Functions
High-Speed Model Knee Control Adaptation
Aiming at the operation needs of 8800B high-speed lockstitch machines, the transmission response speed of the rod is increased by 20%; a light knee push can realize rapid presser foot lifting, which is suitable for the scenario of frequent fabric adjustment during high-speed sewing, freeing hands to focus on fabric straightening;
Precise Stroke Control
The φ7*80 specification is adapted to the transmission stroke of 8800B models, which can accurately control the presser foot lift height within the range of 8-12mm, meeting the switching sewing needs of medium-thick materials and thin materials, with no idle stroke deviation in transmission;
Low-Noise Transmission
A silent bearing is installed at the connection end between the rod and the internal lever, and the transmission noise is ≤35dB, suitable for the low-noise operation needs of high-speed models. The knee press lifting rod ensures quick and quiet presser foot adjustment for high-speed production.
Material Compatibility Advantages
Top (ABS)
It has both rigidity and toughness, is wear-resistant and pressure-resistant, no deformation after long-term pressing, and the surface is treated with skin-friendly processing to reduce knee discomfort during long-term operation;
Rod (A3)
It has sufficient strength and toughness, can withstand the high-frequency transmission impact of high-speed models, no bending or breaking, and ensures transmission accuracy.
