STR SERIES

2023-08-10
●With factory automation equipment using servo systems, overall machine performance can be greatly affected if critical elements are not considered during the design phase.
●Factors, such as backlash can cause premature wear, vibration, inefficiency, poor rigidity and control instability. Long settling times can affect productivity and positioning accuracy. The STR series is our ultra high precision solution that addresses these concerns and offers proven mechanical reliability.
●This versatile solution features programmable output motions with low-wear rolling contact. Larger inertia load transmission is achieved with internal cam ratio reduction while maintaining powerful torque with less motor horsepower. The STR’s unique no-back-lash preloaded mechanism improves the overall dynamics to force output motions to a new level of rigidity and accurate servo controller performance. The compact design reduces footprint while offering high speed rotation with large bending moment capacity.
●STR SERIES
■Zero Backlash – a unique preload mechanism to completely eliminate backlash and deliver motion that is true to input commands
■Highest level of positioning accuracy and runout accuracy, which is difficult to attain with other gearing technologies. Exceptional with direction reversing applications
■Output shaft is a solid piece cross roller bearing designed for durability against axial and radial loads
■Compatible with nearly any servomotor
■Reduction ratios up to 2000:1 are possible using a planetary primary stage
■Lightweight, compact aluminum alloy housing for minimal footprint
■Excellent fit for rotary pick and place applications, large dial tables and robotic joints
■Maintenance free solution using grease lubrication, can be mounted in any position
●STR Series Features
■Oversized hollow output shaft
■ Turret with integral cross-roller bearing
■ Globoidal cam
■ Tapered roller bearings
■ Needle roller cam followers
