| Steel Ball Circulation Mode |
Floating 
Cover plate type
The end cover type
Intubation type
Cutting type
1.Floating
Floating reversing device is the most basic and widely used,with the help of reversing device on the role of the bead groove,forcing the ball rolling along the raceway,over the screw thread raceway after the tooth tip,back to the initial raceway,formed a circular ball chain,suitable for all kinds of diameter and nut style.In all circulation systems,the nut diameter of the floating reversing device can be minimized,suitable for all kinds of precision micro equipment.
2.Cover plate type
Nut with cover plate,suitable for large lead ball screw,large load,high cost performance.
3.The end cover type
Refers to the way in which the steel ball rolls along the groove between the screw shaft and the nut,passes through the through hole on the nut through the path installed on the end cover backer at both ends of the nut,and returns to the original position.It has stronger scraping effect,and the strengthening of the circulating backflow structure increases the function of high rigidity and high speed.It is suitable for the design of high speed light load and low noise.
4.Intubation type
The intubation is an evolution from the floating deflector.To guide the balls into and out of the elbow tube by means of a tongue bevel at the end of the elbow tube inserted into the hole or other form of bead stopper.
5.Cutting type
Cutting type at the same time grasp the small space with two large load characteristics,processing difficulty is higher,is suitable for some special requirements.
| Cautions About Using Ball Screw |
Ball screw assemblies are delicate components.Therefore,extra care must be taken to prevent the ball track from damages that caused by edged component or tools.Meanwhile,the steel ball is very easily fall out of the nut or over stroke.Don't disassemble it.
To prevent steel ball fall out of the nut through the disassembly of screw and nut or over stroke,please be careful while operating.If the steel ball falls out,please contact with ALM Linear Motion for further instruction.Do not attempt to reassemble,which might cause permanent damage to the ball screw.If disassemble is required,please use a transfer pipe which has minor diameter than the screw diameter to transfer the nut to prevent falling out of the steel balls.
