TBI Precision Ground and Rolled Ball Screw SFNI Series
TBI SFNI type ballscrew is belong to Internal Return Series it has ground and rolled screw.
1. Space saving nternal circulate design
2. Low friction force with 1/3 over acme screw
3. Ensure for high accuracies
4. Micro feed with tolerance within in 0.1μm
5. Zero backlash, high stiffness.
For delicate application in industrial application, machine tool and automation application.
1.Ultra high walking precision
Adopt the most advanced technology of three-surface multiple-groove molded grinding and the world patent of position calibration system of guide feeding. Walking precision can reach 0.002 mm/4m.
2.One package shot molding
Adopt world patent of one package shot molding for Ball circuits. It can reduce the assembly tolerance, lower the collision resonance noise between the steel balls and reduce the friction between the ball and the pipe wall to prolong its service life.
Integrated dustproof design can resist dust from the end, the side and the top, thus achieving the effective internal and external dustproof.
4.The stable deep-locked design
The design of super long locking screw is to make sure the deep lock stability of the screw.
5.Through-type oil circuit design
The advantages of through-type oil circuit design are bi-direction lubrication by one-direction oiling and long-lasting lubrication with large oil storage space.
