Frequently Asked Questions
What is the difference between a ball screw and a linear bearing?
A Ball Screw Support bearing, also known as a Support Bearing or BSB, converts rotational motion into precise linear motion using a screw shaft and nut with ball bearings, reducing friction and transferring loads for smooth movement. A Linear bearing, on the other hand, supports and allows free linear movement on a restricted path with minimal friction. They are typically used with linear guides or rails.
What is a precision bearing?
A precision bearing is a bearing manufactured with extremely tight tolerances for applications requiring high accuracy and performance. Precision bearings ensure reliable, smooth operation in industries including aerospace, medical devices, and precision machining.
How Do Ball Screw Support Bearings Improve Machine Performance?
Ball Screw Support Bearings are essential for maintaining the high accuracy and smooth movement of ball screw systems. They support the axial load while minimising deflection and backlash, which improves the overall efficiency, precision, and longevity of the machinery. This ultimately leads to enhanced performance and a reduction in maintenance costs.
What Types of Ball Screw Support Bearings Are Available?
Ball Screw Support Bearings come in various designs, including angular contact and duplex bearings, to handle both radial and axial loads. The specific type of Ball Screw Bearing you need will depend on your application’s load requirements, speed, and space constraints. At Quality Bearings Online, we offer a wide range of Ball Screw Support Bearings to suit every need.
