Product Description
All different ball screw series, you could choice according to your request:
SFU series have three different inverter,
one is round plastic inverter,
one is waist plastic inverter,
another one is waist metal inverter.
this is the very common ballscrew, and the very cheapest one of all the ballscrew series.
have two tolerance: C5 and C7, C5 is grind processing, but C7 is rolled thread,

Product description
Ball screwdata sheets:
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.
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.
PP bag for each linear shaft, Standard exported carton outside for small ordershipping by international express, such as DHL, TNT, UPS
