Product Features

High shaft-end compatibility

The shaft ends have not undergone heat treatment, and the center holes at both ends of the screw shaft are retained, allowing for easy machining of the shoulder dimensions at the shaft ends.

Short lead time

Set the commonly used specifications of screws, thread lengths, and unprocessed lengths at the shaft ends as standard inventory items.

Low price

The precision grade is set using either C5 or C7 in combination with axial clearance, enabling mass production and cost reduction, thus making the price more competitive.

Features of PPR Micro-Sized Nuts

Save space

Designed with a special external circulation method, the nut achieves the same compact size and internal circulation design, taking up minimal space.

Cycling mode

Designed with a 3D S-shaped curved return path, the steel balls in the return section experience a gentle deceleration, which reduces wear and extends service life.

Features of PTR-end plug-type nuts

Save space

A device with a shorter nut length and a 20% to 25% reduction in outer diameter dimension, enabling space-saving designs.

Cycling mode

By adopting composite materials and a structural design with tangential paths, the impact and vibration during the steel ball circulation are effectively reduced, thereby lowering noise levels.
