Linear guide rail and block assembly with Dynamic frictions, greatly decrease motion frictional resistance between them, thus acquire anti-backlash motion and improve motion rigidity of mechanical system.
1) When applying guide assembly in pair, it has “Error Averaging Effect” thus to decrease processing accuracy requirements of basic parts (guide installation surface) and decrease mechanical manufacture cost and difficulty of basic parts.
2)The guide assembly raceway section adopts arc groove with reasonable specific value and low contact stress. The carrying capability and rigidity are increased greatly than flat surface contacting with steel ball point. The rolling friction is decreased evidently in comparison with dual arc raceway.
3)The guide surface is treated with hardening process to make the guide have good adjustability and keep the core in good mechanical property which simply the design and manufacture of mechanical structure
