Functions
Small Industrial Knee Control Adaptation
Aiming at the operation scenarios of 842/8420 small industrial models, the compact 7.5*70 specification is adapted to the machine body layout; knee force can drive the presser foot to lift, facilitating frequent position adjustment of medium-thick materials and improving the sewing efficiency of small industrial workshops;
Precise Transmission Guarantee
The rod body has no transmission gap, which can accurately convert the knee force into presser foot lifting and lowering actions, ensuring uniform stitching of small industrial models and preventing fabric deviation during medium-thick material sewing;
Wear-Resistant and Durable
The top of the actuator is treated with anti-slip texture, no slipping during long-term knee pressing, and the rod body surface is anti-rust treated, suitable for the oily environment of industrial workshops. The presser bar knee actuator boosts efficiency for small-scale industrial sewing operations.
Material Compatibility Advantages
Top (ABS)
Wear-resistant and pressure-resistant, no deformation or cracking after long-term high-frequency pressing, suitable for the use frequency of small industrial models;
Rod (A3)
Balanced strength and toughness, can withstand the transmission impact of small industrial models, no bending or breaking, ensuring transmission stability.
