Product Features
SURELEN Rolled ballscrew 
1.Rolled shaft:Groove hardness is the same to ground ballscrew.
2.Ballnut:The same material and manufacturing process.
3.Ball、Circulation parts:The same to Ground ballscrew.
The combination of rolled ballscrews and ground nuts has replaced the traditional ACME
screws and trapezoidal screws. This makes for a smoother operation while lowering friction and
backlash. Moreover, the new technology has the advantage of faster production speed and
lower prices.
Features of the SURELENI Rolled Ballscrew 
1.Finised rolled ballsdrew in huge stock,delivery time is shorted.
2.Cost advantage.
Rolled ballscrew precision  
SURELEN rolled ballscrew precision :C7-C10 ,the accumulated lead error of any
portion of 300mm in length C7-0.05/300 C8-0.1/300 C10-0.21/300
Note:please contact us if Grade C5,C6 is needed Maximum axial play of ballscrew
General provisions:
NOTE:PMI rolled ballscrews can eliminate axial play by preloading. Please contact our sales
representatives if preloading is required.
As for CA of conversion grade ball screw    
The CA of voncersion grade ball screw is generally 80%-90% of the grinding precision grade. When the average working axial load ≧ 30% dynamic load, should be pay attention.
As for the nuts of conversion grade ball screw 
In principle, the grade of the ball screw nut can be referred to the precision nut, but in order to shorten the delivery time, it is recommended to use the standard screw of the leveling screw.
Description of the conversion grade ball screw  
1. C7-C10 accuracy level is defined as the conersion grade, if you want to grind the screw, shoud be specified it.
2. C5-C6 accuracy level for the precision level, if want to transfer screw, should be specified it.
