The Ball Screw is a high-efficiency feed screw with the ball making a rolling motion between the screw axis and the nut. Compared with a conventional sliding screw, this product has drive torque of one-third or less, making it most suitable for saving drive motor power.
What is a link ball?
The Link Ball is a spherical slide bearing with a ball stud that provides smooth operation with a minimal clearance. With superb abrasion resistance and large oscillating angle, this product is suitable for the link motion mechanism of various types of automated machines.
What is a precision ball screw?
Precision Ball Screw / Spline A Stroke/Rotary unit that has Ball Screw grooves and a Ball Spline groove crossing one another on a single shaft. The nuts of the Ball Screw and the Ball Spline have dedicated support bearings directly embedded on the circumference of the nuts.
What is a Ball Spline shaft?
A ball spline is a type of rolling bearing linear guide, similar to a round shaft and bushing assembly, but with a critical distinction in its operation. The shaft of a ball spline is much like a linear guide shaft, except that the spline shaft has grooves along its length.
What is ball screw stroke?
Stroke: The linear distance in either direction that a ball screw or ball nut travels in moving the load. Temperature: Ball screw assemblies operate with normal efficiency between temperatures of -65 degrees F to 300 degrees F with suitable lubrication.
What is acme screw?
ACME screws are one type of lead screw. ACME screws are designed with strong threads that are most commonly used for lifting. These screws are easier to manufacture than some other designs, but still offer considerable strength.
Why are ball screws so expensive?
Ball screws will always be more expensive – why? That’s easy – there are more parts. A lead screw is merely a threaded shaft and simple nut. The precision of such a device is based on the grind accuracy for the shaft and the resultant play when the nut is installed.
What is recirculating ball screw?
Recirculating ball screw is the mechanical component increasingly used in movement transmission,used to transform a rotary motion into a translational motion. This mechanical component is precise and offer superior performances.
Where are ball splines used?
Ball Splines | NB Ball Spline It can be used in a wide variety of applications including robotics and transport type equipment. The NB ROTARY BALL SPLINE can be used for both rotational and linear motion. It can be used in SCARA robots, the vertical shaft of assembly equipment, and tool changers and loaders.
Do linear bearings allow rotation?
A bearing or bushing can be used for linear or rotational motion. While most bearings and bushings are designed for only one type of motion, there are some parts that can combine both. Allowing for this motion though often requires a larger unit than other bearings relative to the size of the shaft.
How much weight can a ball screw lift?
A ball screw drive translates rotational motion to linear motion or vice versa and can apply or withstand high thrust loads – upward of 750,000 lbs static capacity using a Ø6.
