What are the benefits of using a ball screw over a lead screw?

Ball screws offer higher efficiency, precision, and speed compared to lead screws. Ball screw have lower friction and can transfer higher loads with greater accuracy and repeatability. They require less power to operate and have longer lifespans.

How do you choose the right ball screw for your application?

To choose the right ball screw, you need to consider factors such as load capacity, speed, accuracy, and repeatability. You should also consider environmental conditions like temperature and humidity. It is recommended to consult with a ball screw supplier or engineer to ensure that the ball screw meets your application requirements.

How do you determine the load capacity of a ball screw?

The load capacity of a ball screw depends on factors such as screw diameter, lead, and the number of ball circuits. You can calculate the load capacity using manufacturer-provided formulas or consult with a ball screw supplier or engineer to determine the load capacity for your specific application.

How do you lubricate a ball screw?

Ball screws require lubrication to reduce friction and wear. The appropriate lubricant and lubrication method depends on the specific application and the type of ball screw. It is recommended to consult with the ball screw manufacturer or supplier to ensure that the right lubricant and lubrication method is used.

What are the maintenance requirements for ball screws?

Maintenance requirements for ball screws include regular inspection for signs of wear or damage, cleaning, and lubrication. It is essential to follow the manufacturer's recommendations and guidelines for maintenance to ensure the proper functioning and longevity of the ball screw.

How many types of ball screws are there, and what are their differences?

There are several types of ball screws, including ground ball screws, rolled ball screws, miniature ball screws, and large-diameter ball screws. The main differences between these types of ball screws are in their manufacturing methods, accuracy, load capacity, and application suitability. Consult with a ball screw supplier or engineer to determine the right type of ball screw for your specific application.

Rolled Ball Screw, No Preloading Type (Nut Single Unit) WTF

THK

[Features]
· THK rolling ball screws are low-priced feed screws combined with a threaded shaft that has been subjected to high-accuracy rolling and a special surface-polish finish rather than the thread grinding shaft used with precision ball screws.
· Because all of the ball raceways on the combined ball screw nuts have a thread ground finish, the gap in the shaft direction is smaller, and the operation is smoother, than conventional rolled ball screws.
· Also, an abundant standardized lineup is available so that you can select the product that is best suited for the given application.
· For the threaded shafts, displacement tolerance is also standardized for the C7 and C8 classes other than C10 class, so they can be used for a wide variety of applications.
· After rolling is completed, the ball rolling surface of the screw shaft undergoes a special surface polishing process that polishes the surface to get a roughness of 0.20 a or less, similar to the roughness of a precision ball screw made by grinding.
· The rolled ball screw nuts of THK are durable and smooth as they are subjected to grinding and finishing of the ball rolling surface, just like precision ball screws.
· After rolling, the screw shaft is treated with either high frequency or charcoal immersion quenching, after which it is subjected to special surface grinding and finishing. These manufacturing processes ensure a lower cost of the product compared to the precision ball screws made by grinding.
· These ball screw nuts that have a built-in compact labyrinth seal or brush seal achieve low-friction and high level dust-proofing, making the ball screws' lifespan longer.
· Uses an end cap system that provides stable operation at high-speed rotations.
