Frequently Asked Questions

What is the QA1 Narrow Spherical Plain Bearing used for?

The QA1 NPB4T narrow spherical plain bearing is used in high-misalignment applications such as rod ends, linkages, and suspension systems. Its PTFE liner reduces friction and wear, making it suitable for industrial machinery, automation, and off-highway equipment where angular movement and load support are required.

What are the specifications of the QA1 NPB4T bearing?

The QA1 NPB4T has a 1/4 in bore diameter, 21/32 in outside diameter, and 0.25 in outer ring width. It uses a PTFE liner material, operates in the inch system, and is designed for high misalignment. The manufacturer part number is NPB4T.

Where to buy the QA1 NPB4T bearing worldwide?
