  • When should you use dual guide rails? - Linear

    Thomson offers LinearLube® grease which is suitable for most industrial applications. DO NOT use any type of dry lubricant (PTFE powder, graphite powder, etc.) with any recirculating ball or roller type of bearing. While these lubricants are good for sliding motion, they do very little to aid rolling friction.
