Advantages of Ball Screw Bearing Block

The material is pure steel for extended service life.

Incorporates tighter preload tolerances for chatter-free cutting and tighter width tolerances for easy assembly without regrinding the end caps.

Revolutionary cage design accommodates more balls for higher load capacity.

The double row bearing series is equipped with one-piece, low-torque contact seals that prevent contaminant ingress, ensuring reliable bearing operation and extended bearing life.

Flanged (MMF) and non-flanged (MMN) series bearings are available to simplify mounting of standard and swivel nut types.

Materials of Ball Screw Bearing Block

Chrome Steel

Ball screw bearings made of chrome steel are used for a wide range of general industrial applications due to their high hardness, strength, wear resistance and relatively low cost.

Stainless Steel

Ball screw bearings using stainless steel have good corrosion resistance and are suitable for wet or corrosive environments, maintaining a high level of durability, making them particularly suitable for special applications such as medical equipment and food processing.

Ceramic

Ball screw bearings made of ceramic have the advantages of light weight, high heat resistance, and low friction, improving performance and making them suitable for high-speed and high-temperature environments.

Key Manufacturing Process of Ball Screw Bearing Block

Raw Material Preparation
Selection of high quality bearing steel or other suitable materials to ensure uniformity of material and accuracy of alloy composition.

Cold Drawing or Hot Extrusion
The raw material is cold-drawn or hot-extruded to the desired shape, such as a round or square cross-section.

Rough Turning
The extruded or cold-drawn material is rough turned to form the initial bar shape.

Hardening
The roughly turned bar is hardened to increase its hardness and strength and to increase resistance to wear.

Grinding
The hardened screws are precision ground by a grinder to ensure the smoothness of the surface and the accuracy of the dimensions.

Thread Rolling
Threads are rolled on the screw to ensure the accuracy and quality of the threads.

Ball Guiding Groove
Manufacture the guiding groove on the surface of the screw for accommodating the ball to ensure the smooth guiding of the ball in the process of movement.

Assembling
Assembling the manufactured screws with bearing jackets, end supports and other components to form the final ball screw bearings.

Inspection
Quality inspection of the finished products, including dimensional measurement, thread quality, surface finish, etc., to ensure that the products meet the design requirements.

Lubrication
Add appropriate lubricant inside the ball screw bearing to improve the friction performance and life.

Features of Ball Screw Bearing Block

Efficient Transmission: Adoption of ball structure reduces friction resistance and improves transmission efficiency.

High precision: Ball screw bearings have high positioning accuracy and repeatability, suitable for applications requiring high precision.

Strong load bearing capacity: Able to withstand large axial load and radial load, suitable for applications requiring high load bearing capacity.

Automatic preload: Due to the automatic preload of the balls, the ball screw bearings are less likely to produce clearance during operation, which improves the rigidity of the system.

High-speed movement: Due to the light weight and small inertia of the balls, ball screw bearings are suitable for high-speed movement.

Low friction and high efficiency: The rolling of ball reduces the friction loss and improves the energy utilization efficiency.

High Reliability: Simple structure, fewer parts, therefore higher reliability and lower maintenance costs.

FAQ

Q: What is a ball screw bearing?

A: Ball Screws
It is composed of a threaded shaft, a nut, and a series of ball bearings. The ball bearings are housed in the nut, which is then mounted on the threaded shaft. As the threaded shaft rotates, the ball bearings move along the thread, causing the nut to move linearly along the shaft.

Q: What is the purpose of a bearing block?

A: A pillow block bearing (or plummer block) is a mounting used to support a rotating shaft, using a bearing in a housing which is bolted to a foundation with the mounted shaft in a parallel plane to the mounting surface and perpendicular to the center line of the mounting holes, as contrasted with various types of flange.

Q: What is ball screw backlash?

A: Backlash– The free movement of a ball nut on a stationary ball screw caused by small gaps between the ball bearings and the ball nut or the ball bearings and the ball screw. A ball screw can be ordered preloaded, which means there is minimal backlash.

Q: How do you install ball bearings?

A: A typical bearing installation, which is staked into the housing, is assembled with a mating clevis, bolt, nut, washers, and plain and flanged bushings.In most applications, the bolt is preloaded with the nut to clamp-up the ball and force the ball to rotate on the race ID.

Q: What is the main reason for using ball bearings?

A: Ball bearings are usually used in machines that have a lot of moving work. Ball bearings reduce the friction so that machinery can work smoothly. The sliding friction gets converted to rolling friction which is much less and power dissipation is reduced.
