Description

Notes:

  1. If you have special requirements on machining, please let us know before placing order, so that we can customize for you.
  2. If you need to change the size of flexible coupler bore according to your motor shaft diameter, confirm with us before placing order.
  3. This item has end machining, and the overall length that we mentioned above includes the end machining part.
  4. Due to different measuring tools, may exist slightly differences in length, but it won’t affect the use.
  5. After receive the package, please check the product at first. If there any problem, let us know in time, so that we can provide after-sales services for you.

Package includes:

Attention:

  1. End Support Units include the FK Fixed Side and the FF Floated Side.
  2. We will install the nut on the screw in advance. There are some steel balls inside the nut, please don’t remove it from the ball screw. Otherwise, those steel balls will fall out and hard to put them back.
  3. Maintenance: customers may lubricate the ball screw with hydraulic carbon oil, what we also called No.46 machine oil.

High Quality: this product is made of high-quality steel, which stands up to wear and tear, and can meet high load capacity requirements.

Accuracy Grade C7: with bearing fits less than 0.03 mm so that the actuator rod doesnt wiggle so much when operating.

Power Saving:

Excellent overall performance, considering it saves power. Meanwhile, it yields higher mechanical efficiency than traditional Acme alternatives.

Mute Operation:

The CNC linear rail kit bears very little sliding friction between the nut and screw. Thus, downtime for maintenance and parts replacement is cut, as well as the lubricating demand.

Applications:

  1. Ball screws are used in automobile power steering to translate rotary motion from an electric motor to axial motion of the steering rack.
  2. Because its low frictional resistance, they are also used in machine tools, robots and precision assembly equipment.
  3. High precision ball screws are used in steppers for semiconductor manufacturing and so on.

* The picture above is for reference only; the model of Support Units depends on what you order.
