The Cylindrical type with M-thread at the Nut end. The Nut should be mounted using M-thread. It is suitable for mounting with cylinder. Accuracy grade of GLM series are based on C3 and C5 (JIS B 1192-3). According to accuracy grade, Axial play 0 (Preload: C3) and 0.005mm or less (C5) are available. GLM series of screw shaft screw material S55C (induction hardening), nut material SCM415H (carburizing and hardening), the surface hardness of the ball screw part is HRC58 or higher.

It is cylindrical single nut which is compact. The nut should be mounted by clamping on the keyway on the nut outer and nut end surface. Accuracy grade of TXM series are based on C3 and C5 (JIS B 1192-3). According to accuracy grade, Axial play 0 (Preload: C3) and 0.005mm or less (C5) are available. TXM series of screw shaft screw material S55C (induction hardening), nut material SCM415H (carburizing and hardening), the surface hardness of the ball screw part is HRC58 or higher.

Since there are both right-side thread and left-side thread on a shaft, it has bi-directional function. The SXM series has two types of accuracy grades, JIS C3/C5. Axial clearance is available in 0mm (preload: C3) and 0.005mm or less (C5) depending on the accuracy class. SXM series of screw shaft screw material S55C (induction hardening), nut material SCM415H (carburizing and hardening), the surface hardness of the ball screw part is HRC58 or higher.

KGG has two types of Compact High Speed Precision Ball Screws: DKF & DKFZDSeries List
KGG offers a large-lead version ball screws.
Series List
Specially used for electric injection molding machines, high load, high speed operation and long lifeSeries List
Application: Large and heavy-duty CNC lathes, CNC boring machines, CNC milling machines, large steel smelting equipment, jacks and spinning machines and other mechanical equipment.Series List
High transmission efficiency and positioning accuracy, long service lifeSeries List
KGG has 5 ball screws with other circulation methods: JF miniature ball screw, CMFZD external circulation cannula embedded gasket preload type, CTF external circulation cannula protruding type, DGF and DGZ internal circulation end caps type.Series List
Application: Semi-conductor industries, Robots, Wood machines, Laser cutting machines, Transporting equipment. Features: 1. Compact and high positioning: It is a compact design using nut and support bearing as an integral unit. 45-degree steel ball contact angle make a better axial load. Zero backlash and higher stiffness construction give a high positioning. 2. Simple installation: It is installed simply by fixing the nut on the housing with bolts. 3. Rapid feed: No inertial effect produced by the integral unit rotating and the shaft fixed. Can select smaller power to meet the rapid feed requirement. 4. Stiffness: Have a higher trust and moment stiffness, because the integral unit have an angular contact construction. There is no backlash while rolling. 5. Quietness: Special end cap design allows steel balls circulating inside the nut. Noise generated by high speed operation lower than ordinary ball screw. We have two types of light load and heavy load rotating nuts: XDK & XJD series.The rotating nut combination unit is a transmission system that converts the rotary motion of the ball nut into the linear motion of the nut itself (or ball screw). It is an extension product of the ball screw pair, and its main components are composed of a ball screw pair, a rolling bearing pair, a nut seat, a pre-tightening adjustment (locking) device, a dust-proof device, and a lubricating oil circuit.Series List
