Rolled Ball Screw, No Preloading Type (Nut Single Unit) WTF
THK
[Features]
· THK rolling ball screws are low-priced sending screws that modify the screw grinding shaft used in precision ball screws and use a new screw shaft created by combining high accuracy rolling pressing with special surface grinding finishing.
· Because all the ball rolling surfaces or the combined ball screw nuts have undergone grinding finishing, the gap in the shaft direction is smaller than conventional rolling ball screws, providing smooth operation.

· Aside from the C10 class, the shaft tips for the C7 and C8 classes are both standardized for movement amount tolerance, 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, finishing the surface at a roughness of 0.20a or less, identical to the precision ball screw product line after screw grinding.
· Rotating ball screw nuts also undergo a ball rolling surface grinding and finishing process just like precision ball screws, which provides durability and smooth operation.
· After rolling is completed, the screw shaft is treated with either high frequency or charcoal immersion quenching, followed by a special surface grinding and finishing process. Due to the manufacturing methods used, this product is comparatively cheaper than the precision ball screw line made through grinding.
· Because the ball screw nut has either a compact labyrinth seal or a brush seal built-in, it operates with low friction and high level dust-proofing, lengthening the life of ball screws.Screw Shaft O.D. d(Ø) Product Type Lead(mm) Accuracy Grade Flange Shape Axial End Type 25 Rolled Ball Screw 50 - Round Shape, 2 Set Screw Flats at both ends - From: ₹ 40,229.31 Days to Ship: 22 Day(s) or more

FAQ Ball screw
- Question: What are the benefits of using a ball screw over a lead screw?
- Answer: 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.
- Question: How do you choose the right ball screw for your application?
- Answer: 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.
- Question: How do you determine the load capacity of a ball screw?
- Answer: 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.
- Question: How do you lubricate a ball screw?
- Answer: 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.
- Question: What are the maintenance requirements for ball screws?
- Answer: 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.
- Question: How many types of ball screws are there, and what are their differences?
- Answer: There are several types of ball screws, including ground ball screws, rolled ball screws, precision 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.
