High-Load High-Precision Roller Linear Guide for Semiconductor Equipment

This high-load & high-precision roller linear guide is specially designed for semiconductor equipment. Adopting roller line-contact structure, it delivers ultra-high rigidity, heavy-load capacity and minimal deformation. It ensures stable micron-level precision motion, serving as a reliable equivalent to THK and IKO for high-precision semiconductor processing.
NF Internal Circulation Fixed Ball Screw
Internal Circulation Ball Screw

NF Internal Circulation Fixed Ball Screw

The NF Internal Circulation Fixed Ball Screw is an upgraded precision motion transmission component evolved from traditional slide ball screws, composed of high-precision screw shafts, locking nuts and circulating steel balls. It realizes efficient mutual conversion between rotary motion and linear motion with optimized rolling friction structure, delivering superior friction performance, stable operation and high transmission accuracy. Manufactured by a leading Chinese ball screw manufacturer with decades of R&D experience, this internal circulation fixed ball screw adopts advanced processing and heat treatment technology, featuring stable quality, complete precision grades and fast delivery, suitable for diverse industrial equipment and precision instrument applications.
GJAIIZA Heavy Duty Roll Spline Subdimension Series
GJA Type

GJAIIZA Heavy Duty Roll Spline Subdimension Series

The GJAIIZA Heavy Duty Roll Spline Subdimension Series is a heavy-load, high-precision rolling spline component designed for rigorous industrial motion applications. Built with a reinforced sub-dimensional structural framework, this roll spline delivers reliable torque transmission and smooth linear motion while sustaining substantial radial, axial and moment loads. It features minimized rotational backlash, enhanced structural rigidity and outstanding wear resistance, making it ideal for heavy-duty automated machinery under continuous high-load working conditions. Manufactured with precision forming and rigorous quality inspection, the GJAIIZA heavy-duty subdimension roll spline balances compact installation footprint with robust load capacity, supporting both standard and custom motion solutions for heavy industrial sectors.
DKG type mounting connection dimensions

DKG type mounting connection dimensions

The DKG Type Mounting Connection Dimensions are specially customized for high-performance ball screw rolling spline composite units, a newly developed integrated rolling functional component engineered for modern automated and intelligent production lines. This all-in-one motion unit integrates linear and rotary motion functions in a single compact structure, mainly consisting of a hollow screw spline shaft, ball nut rolling bearing composite assembly, and spline sleeve rolling bearing composite unit. With standardized DKG mounting specifications, it features versatile compound motion capabilities, lightweight structure, high-speed quiet operation and simple installation. It is widely applied in SCARA robot Z-axis systems, automatic dispensing machines, welding equipment, automatic loaders, precision testing machines, and machining center ATC automatic tool change devices, serving diverse mechanical scenarios requiring combined linear and rotary motion.
GGY Rolling Arc Guide
GGY Rolling ARC Guide Rail

GGY Rolling Arc Guide

The GGY Rolling Arc Guide is evolved from the mature GGB precision ball linear guideway. While inheriting multiple core strengths of the GGB series, it enables arc or circular motion with arbitrary diameters and breaks the dimensional constraints that exist in conventional bearing and rolling support machining solutions. The GGY rolling arc guide features a distinctive structural design that achieves zero clearance operation and excellent overload capacity. In theory, larger-diameter GGY arc guides bring greater convenience in design, fabrication, installation and maintenance. It serves as a reliable circular motion component for large rotating structures and precision equipment.
Standard Planetary Roller Screw Product Series

Standard Planetary Roller Screw Product Series

The Standard Planetary Roller Screw Series is a classic and high-reliability linear transmission product in the planetary roller screw family. Classified by structural configuration and roller motion characteristics, roller screw pairs are divided into standard, recirculating, and reverse planetary types. Distinct from other variants, the standard planetary roller screw features fixed-axis roller operation: its rollers only perform autorotation and revolution during working cycles, with no axial displacement relative to the nut. Adopting mature planetary thread meshing technology, this series delivers ultra-stable transmission, uniform load distribution and consistent linear motion accuracy, serving as the most widely applied foundational linear drive component for medium and heavy-duty industrial precision equipment.
