Frequently Asked Questions

What is the NTN BST40X72-1BP4 ball screw support bearing used for?

The NTN BST40X72-1BP4 is an angular contact thrust bearing designed to support ball screws in precision linear motion systems. It handles axial loads in CNC machine tools, robotics, and industrial automation where high accuracy and rigidity are required.

What are the specifications of the NTN BST40X72-1BP4 bearing?

This NTN bearing has a 40 mm bore, 72 mm outer diameter, 60° contact angle, ABEC 7 precision, and a thermoplastic cage. It is a single, open angular contact thrust bearing (not matched) with metric dimensions and part number BST40X72-1BP4.

Where to buy the NTN BST40X72-1BP4 bearing worldwide?

3G Electric supplies the NTN BST40X72-1BP4 bearing worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

How to select the correct NTN ball screw support bearing for my application?

Select based on bore size, contact angle, and precision class. For the BST40X72-1BP4, ensure your shaft diameter is 40 mm and your application requires a 60° contact angle and ABEC 7 accuracy. Use a single bearing if preload matching is not needed.
