BALL SCREWS & LINEAR GUIDES

Core Components for High-Precision Machine Tools

Standard Linear Guide Rail

GGB is the earliest developed LM guide and is one of the widely used guides. Design with equal 45o contact angle, which makes equal load in vertical upside ,vertical downside, horizontal left and horizontal right four orientations(see fig-1), and it has heavy rated load, good rigidity, high stiffness and strong torque resistance of three directions, so it also calls four direction equal load LM guide.

High Speed Ball Screw
The DKF High Speed Precision Ball Screw is a premium-grade motion transmission component engineered and produced by a top-tier Chinese industrial ball screw manufacturer. Constructed with precision-machined screw shafts, durable nuts and circulating steel balls, it efficiently converts rotary motion to linear motion and vice versa. Optimized for high running speed and ultra-high motion accuracy, this upgraded rolling friction ball screw delivers lower friction loss, superior operational stability and consistent precision. Manufactured with advanced imported processing technology and mature heat treatment craft, it features reliable quality, long service life and cost competitiveness, ideal for high-precision industrial equipment and precision instrument applications.
GJA Type
The GJAIF Roll Spline Subdimension Series is a high-precision rolling spline component supplied by Chinese manufacturer Gongyi. It integrates compact sub-dimensional structure design to realize accurate torque transmission and smooth linear motion, featuring stable running performance, high matching precision and favorable cost performance. Available for direct factory procurement, this roll spline series delivers reliable quality at competitive prices to satisfy diverse precision motion control demands across multiple industrial equipment.
Ball screw spline
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 Rail
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
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.
