Our factory specializes in manufacturing high-precision screw nuts,
the core transmission components for CNC equipment, precision
machine tools, automated production lines, woodworking machinery,
transmission equipment and lifting devices. Primarily converting
rotary motion into linear reciprocating motion, they realize
precise transmission, positioning, lifting, pushing and fine-tuning
feeding.
They are widely adopted in machinery mold, CNC machining, automated
equipment, woodworking machinery, conveying & lifting equipment,
precision hardware equipment and other industries. The fitting
accuracy, wear resistance and transmission smoothness of screw nuts
directly determine the operating precision, positioning accuracy
and overall service life of complete machines.
Our matched sets of screw nuts are elaborately forged from premium
materials including high-grade 45# steel, 40Cr alloy steel and
20CrMnTi carburizing alloy steel. These materials feature compact
texture, high toughness, strong load capacity and outstanding wear
resistance.
Each product is processed via multiple precise manufacturing
procedures: integral quenching & tempering heat treatment,
carburizing quenching hardening, precision finishing turning,
precise thread grinding, accuracy matching & calibration and stress
relief treatment. These steps effectively eliminate internal
processing stress and prevent common defects arising from long-term
reciprocating movement, such as thread stripping, abrasion,
loosening, jamming and positioning deviation.
The regular thread profiles ensure uniform fitting clearance and
tight meshing without slackness. The transmission runs smoothly
without lag, delivering high positioning accuracy and tiny repeat
positioning error, sustaining stable precision transmission
performance over long-term operation.
Our full product range covers trapezoidal screw nuts, ball screw
nuts, precision fine-tuning screw nuts, lifting screw nuts and
left-right hand screw nuts. Compatible with various working
conditions including low-speed heavy load, high-speed precision
transmission, high-frequency reciprocation and lifting & pushing,
they are wear-resistant, robust, anti-thread-stripping, high
load-bearing, low-noise and long-lasting in service.
Customization is available according to customers’ equipment
parameters and mounting requirements, including non-standard
diameter, lead, thread pitch, length, thread profile, mounting
holes, flange structure and left-right hand threads. We accept
custom processing based on customer drawings and samples.
As an original physical manufacturer integrating production and
sales, we implement multi-process full quality inspection
throughout production. Standard specifications are kept in abundant
stock with stable lead times. We accept bulk orders and rush custom
orders, serving as a premium and reliable supplier of transmission
parts for all machinery manufacturers.
