GMT Linear Motion Elements include ball screw, ball screw support unit, coupling, crossed roller rails, miniature linear guides those are key components apply to linear motion.
Flexible Coupling – Full stainless steel bellows coupling - Set screw Offset of angular, parallel, or axial deviation are individual allowed value, so couple reasons of axial offset appearing at same time would reduce the unit allowable value.
Flexible Coupling – Oldham coupling with aluminum bronze spacer - Set screw Offset of angular, parallel, or axial deviation are individual allowed value, so couple reasons of axial offset appearing at same time would reduce the unit allowable value. Suit for high wrench torque, high rotation. In case of parallel deviation over 0.1, abrasion of the insert is direct ration to load torque, offset, and rotation numbers. Available options for key way per inner diameter are bigger than 6mm.
Flexible Coupling – Oldham coupling with carbon resin spacer - Set screw Operating temperature: -40oC~90oC Offset of angular, parallel, or axial deviation are individual allowed value, so couple reasons of axial offset appearing at same time would reduce the unit allowable value. Available options for key way per inner diameter is bigger than 6mm. (Refer to FS-PC)
★ Using crossed roller guiding type, V-grooved and cross-roller are used for line contact transmission in the structure to achieve high-precision movement and load-resistant performance.
