Use of linear motion ball Truck Tyre advantages:1. Can start the flow of exposure dynamic friction resistance friction resistance a very small so you can save energy easy to get a higher velocity.2. The load increases but not sensitive to changes in friction coefficient so heavy the friction coefficient is extremely small the same longterm accuracy can be obtained longterm mechanical life.3. Linear motion Truck Tyre good interchangeability easy to install saving time to the mechanical structure is novel small amount of light of the acteristics.4. Save to oil procedures to simplify the lubrication maintenance purposes.5. Both sides of the additional oil seal Truck Tyre also applies to feign matter dust are me easily perated place.
