Toothless nut L is L, R L represents a right-hand axis rotates clockwise, the table moves to the left .R axis represents a clockwise rotation, the table moves to the right. Nut with a toothless What are the benefits? 1. perfect appearance and accuracy can improve your product market competitiveness. 2. Using toothless guide rod friction drive, in addition to reducing noise, but also can greatly avoid backlash and rail offsets, to ensure the operation, the measurement accuracy, but also can switch to fast-moving, but also accelerated the fixed line and Measurement Speed ??3. use optical axis and toothless screw brake accurate than using a belt or worm or friction-driven approach of the vehicle, the accuracy to be higher. 4. advance about freely, using Zhuoyi ZR toothless when the guide bar, the left propulsion coaxially mounted on the right propulsion can achieve forward and backward movement of the different effects. 5. smooth movement, linear motion and rotary motion with smooth smoothly progressive resistance, is the ability to load homogenized ideal configuration. 6. smooth rotation, both sides of the cage-like configuration of the circumference of the ball, no matter whether the group can be installed in any direction vertical to obtain a smooth smooth rotary motion. 7. fully interchangeable with IEC-type linear optical axis with full interchangeability, can optionally be used in combination with the axis. 8. Product Model: ZR10R, ZR10L, ZR15R, ZR15L, ZR20R, ZR20L, ZR25R, ZR25L ﹝ Note: L represents L \ R represents right-handed ﹞.
