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
