Frequently Asked Questions

What is the QA1 Narrow Spherical Plain Bearing used for?

The QA1 Narrow Spherical Plain Bearing is used in high-misalignment applications such as suspension linkages, steering systems, and industrial machinery where angular movement is required. Its PTFE liner reduces friction and wear, making it suitable for automotive, motorsport, and heavy equipment environments.

What are the specifications of the QA1 NPB7T bearing?

The QA1 NPB7T bearing has a 7/16 in bore diameter, 29/32 in outside diameter, and 0.343 in outer ring width. It uses a PTFE liner material and is measured in inches. This narrow spherical plain bearing is designed for high-misalignment applications and is manufactured by QA1.

Where to buy QA1 NPB7T bearings worldwide?

You can source the QA1 NPB7T bearing through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead times on this and other QA1 bearing products.

How to install a QA1 spherical plain bearing?

To install a QA1 spherical plain bearing, press the bearing into a properly sized housing bore using an arbor press, ensuring alignment to avoid damaging the PTFE liner. Lubricate the shaft and bearing bore lightly before assembly. Always follow manufacturer guidelines for press-fit tolerances and avoid hammering directly on the bearing.
