Ball Screw
Product description
High Reliability
TBI MOTION or ERSK ball screw has very stringent quality control standards covering every production process. With proper lubrication and use,trouble-free operation for an extended period of time is possible.
Smooth Operation
The high efficiency of ball screws is vastly superior to conventional screws. The torque required is less than 30%. Linear motion can be easily changed from rotary motion.
High Rigidity and Preload
When axial play is minimized in conventional screw-nut assemblies, the actuating torque becomes excessive and the operation is not smooth. The axial play in TBI MOTION or ERSK precision ball screws may be reduced to zero by preloading and a light smooth operation is still possible. herefore, both low torque and high rigidity can be obtained simultaneously.TBI MOTION or ERSK ball screws have gothic arch groove profiles which allow these conditions to be achieved.
Circulation Method
Ball return tube method.(V,E,S,Y type);Ball defelector method.(I,U,M,K type)
High Durability
Rigidly selected materials, intensive heat treating and processing techniques, backed by years of experience,have resulted in the most durable ball screws manufactured.
Material and Heat Treatment
Internal Return ball screw
Feature
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.
Application
For delicate application in industrial application, machine tool and automation application.
Ball screw SFU Series:
Matched parts:
Packing and shipping
PP bag for each ball screw, Standard exported carton outside for small order. Wooden box outside for big quantity or very long ball screw shaft
Our Services:
We have professional personnel to operate.
We can process according to your drawings or your requirements custom-made production.
If you have any requirements, or any questions, Please kindly let me know, I am very glad to service you and reply you ASAP.
Company Information:
12years expenrience to produce ball screw and matched parts, like ball screw nut, nut housing, end supports, couplings. And other bearings, linear shaft, linear guide, linear bearings. There are Two Processing Centers which are produced linear blocks and machinized according to the drawings. The max machinized length can be arrived 6000mm.
Our principle:
Quality first, credibility is the key, the price followed
Thank you very much
We are waiting your inquiries
