Precision Ball Way Modules Features
TSUBAKI Precision Ball Way Module is a simple unlimited linear motion travel bearing with two grooves machined in one side of the track and the slide unit. The slide unit incorporates a ball return tube with proprietor recirculation unit and tube fixture. Simple Mounting Accuracy Simple design of the TSUBAKI Precision Ball Way Module permits easy mounting by adjusting each slide unit contact with the rail track. Four Way Directional Rated Load When a pair of ball way units are mounted in parallel, the system is capable of withstanding loads in all directions, including moment loads. High Performance and Simple Construction The adoption of return tubes for ball circulation, simplifies the construction of the slide unit and enables high speed travel.		High Load Capacity TSUBAKI Precision Ball Way Modules have high load carrying capacity and great rigidity because of the relatively large diameter steel balls used, and the corresponding size circular arc ball grooves.
System TSUBAKI Precision BAll Way Modules has two types. Please select according to mounting method and preload.   M-T\w M-TC   Mounting method Upper Press Center Press Preload Low ordinary preload Ordinary high preload Designation Accuracy Standards TSUBAKI Precision Ball Way Modules are classified into five categories according to dimensional tolerance as shown in charts below. The pair variation for Height "H" is only applicable when Ball Ways are used in matched pairs and mounted on the same plane. The pair variation for Width "W" is the value for bearings in matched pairs mounted on the same rail.
