Guided precision motion is most often thought of in the linear form which is used extensively in machinery and automation applications. Sometimes curved motion is better suited to an application. Examples might include moving a sensor or welding torch around the circumference of a pipe, or a complete 360-degree rotary table for indexing a complex assembly operation to variousangles.

- 11. Curvilinear Motion Systems Linear Rotary Curved Linear + Curved = Curvilinear
- 12. Guide Wheel Based Motion Basic principle Guide wheel rolls on matching track surface • Wheels are ball bearings with external running surfaces • Rails are linear profiles with running surfaces • Rings are curved rotary profiles with running surfaces
- 13. Guide Wheel Based Motion Key Advantages Vee surfaces generate a “wiping” action when used on matching linear vee rails • Difference in peripheral speed = velocity gradient Works in harsh environments exposed to dust, dirt or debris • Wiping action pushes debris out of the way • Often the best solution for dirty applications
- 14. Guide Wheel Based Motion Key Advantages Bearing balls are internal, protected and lubricated for life • Seals or Shield options Big advantage over recirculating ball linear guide technology • Balls run on exposed rails directly • Limited seal protection • Debris ingress leads to rapid failure
- 15. Guide Wheel Based Motion Key Advantages Provides smooth & quiet operation with high load carrying capacity • High quality bearing grade steel Carbon and stainless steel • Hardened for durability • Precision ground surfaces Very low stiction and coefficient of friction Industrial grade and performance • Suitable for continuous use
- 16. Guide Wheel Based Motion Key Advantages Adjustable eccentric bearing mount • Set preload between wheel and rail/ring • Adjust play due to wear • Longer usable life • Replace rail/ring, or wheel Profile rail must replace both
- 17. Motion Components Guide Wheel Designs Slimline bearing type • Single row ball bearing • Low profile, lower capacity • Lowest cost Twin bearing type • 2 individual ball bearings • Compliance, smoother running • Tolerates misalignment Slimline Twin Double Double row bearing type • Single piece double row ball • Higher load capacity • Slightly more debris tolerance Floating bearing type • Needle rollers • Axial movement • Prevents binding on parallel rails Floating
