Purchase Notes

SM spindle swivel joints from Taiwan are positioned in the high-end machine tool industry and have long been widely recognised by designers, especially in Japan, Europe and the USA, and are also the designated products of many leading machine tool manufacturers.

1. When replacing SM rotary joints, please ensure that you have measured the size of the joint threads (M10 x P1.0, M12 x P1.25-LH, M16 x P1.5-LH) so that the threads do not match and cannot be installed.

2. When purchasing SM rotary joints, please do not believe that domestic imitation products can replace and achieve the same effect of SM. (It has been proven by our customers many times that domestic imitations are prone to leakage and most of them have a service life of less than two months)

3. In order to ensure your legitimate rights and interests, please try to sign a formal purchase and sale contract with us. We do not provide quality assurance and after-sales service for SM rotary joints not purchased from us.
