Curvilinear Motion Systems LinearRotaryCurvedLinear + Curved = Curvilinear

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

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


  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


  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


  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

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

  Studded Wheel Journals•  Mount into through holes

  Standard heel plates  Custom machinery

  Blind Hole Type•  Mount to solid base (blind)

  Thick mounting base  Adjust from the front

Motion Components Guide Wheel Standard Sizes

  70-degree vee  Based upon OD

•  13•  18•  25•  34•  54

Motion Components Guide Wheel Standard Sizes

  90-degree vee  Based upon OD

•  64•  95•  120•  128•  150

  Up to 50kN radial capacity on the 150mm bearings

•  11,000+ lb-F

Motion Components Linear Guide Rail/Track: Heavy Duty

  90-degree vee  Size 25 and 33

Motion Components Linear Guide Rail/Track: Double Edge Spacer Slides

  70-degree vee  Section widths from 12mm up to 120mm

Motion Components Linear Guide Rail/Track: Single Edge Spacer Slides

  70-degree vee  Use in pairs for wider mounting, high moment load capacity  Available with gear rack cut in back face

•  Already parallel to vee slide = no assembly alignment!

Motion Components Linear Guide Rail/Track: Single & Double Edge Flat Slides

  70-degree vee  Does not include the spacer material  Lower cost, lower weight

Application Curved Machine Doors Flat slide with rolled radius to guide machine doors

  Exposed to process debris, metal chips and metal fines

Application Machine Doors Flat slide and vee bearings to guide machine doors

  Exposed to process debris, metal chips and metal fines  Spacer allows debris to fall through

Motion Components Linear Guide Rail/Track: Precision Grades

  P1 – Fully ground, high accuracy  P2 – Ground on key surfaces  P3 – Not ground, lowest cost

Motion Components Assembled Carriage Plates

  Pre-designed for use with linear rails  Aluminum plate with guide wheels mounted

•  Wheel covers or track wipers•  Threaded holes for mounting

Motion Components Rotary Guide Rings

  Many standard configurations, versions and options  Matching cross section to the linear rails

•  Allows for combining straight to curved motion profiles

  For use with the guide wheels, and/or the carriage plate assemblies

Motion Components Rotary Guide Rings: Ring Disc

  Ring made from a solid plate•  External vee surfaces•  Optional gear teeth

Motion Components Rotary Guide Rings: Vee Rings
