TECHNOLOGY All Modern Linear products incorporate the benefits of guide roller technology for customer applications: Linear guide rollers are based on the design of radial ball bearings. The load carrying balls travel in a circular path and are retained and separated from one another. Current ball bushing and ball rail linear systems have a recirculation path that requires the balls to make a quick change in direction. Vibration occurs when the balls collide entering and leaving the load zone. Linear guide rollers are very quiet as a result of the ball separation. Noise is magnified in...

GUIDE ROLLER COMPONENTS BUSHINGS GUIDE ROLLERS Knurled surface on eccentric bushing for superior hold at adjustment position. superior smoothness and low noise. Drop in replacement for existing Drop in replacement for existing adapter bushings. guide rollers. Nickel plated for corrosion resistance. 52100 or 440 stainless steel. Sealed or shielded. TRACK Single and double edge options. V Edge is case hardened to 49-52 RC. TRACK ASSEMBLY square edge. Custom integration of all components into linear slide. Track can be bolted or welded to steel beam.

GUIDE ROLLERS SIZES GUIDE ROLLER LOAD CAPACITY (LBS.) SIZE VW-1 VW-2 VW-3 VW-4 VW-4XL Working load capacities reflect lubricated roller/track interface. Ratings based on 2 million inches of travel life. LA G Ground, double row angular contact ball bearings, ABEC-5, pre-lubricated with NLGI #2 grease.

2 new styles of linear guide that incorporate a unique patent-pending compliant rail feature. • Ideal for transport applications. • Rigid rail version also available. The compliant rail design automatically adjusts for machining inaccuracies, misalignment and tolerance stack up to maintain fit up between the rail and carriage. Compliant rail feature incorporated into a "U" shaped aluminum extrusion. 3 roller, in-line carriage design. Rollers are fixed, no adjustment required. • 4 roller carriage design offers good load • Ideal for single rail applications.

VECTOR TRIO LINEAR GUIDE 3 roller carriage gives a compact design. Patent pending compliant rail feature. No need to adjust carriage fit up. Compliant rail adjusts to system inaccuracies.

MODERN LINEAR The fixed bushing should be used to carry the heaviest loading. Preload the adjustable bushing so that the roller can just be turned by hand. Over-tightening the preload will cause premature wear of the components. CENTER DISTANCE FORMULA

APPLICATIONS ELECTRONICS Many of the same benefits of guide rollers in medical applications are important for the electronic and semiconductor industries as well. Smoothness is particularly important in wafer transport applications. Compliant systems are easy to install and run smoothly on light weight machine frames. Guide rollers are resistant to contaminated environments. MEDICAL Guide rollers are smooth and quiet compared to recirculating ball guides. The bearings are permanently lubricated and sealed from the environment. Guide rollers can be run without external lubrication between...
