Product Description

The QA1 Narrow Spherical Plain Bearing (SKU 806LX5, MPN NPB12T) is a high misalignment spherical bearing with a 3/4 in bore diameter, 1 7/16 in outside diameter, and 0.593 in outer ring width. This inch-system bearing features a PTFE liner material.

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 rod ends, linkages, and suspension systems in motorsports, industrial machinery, and automation. Its PTFE liner reduces friction and wear under oscillating loads.

What are the specifications of the QA1 NPB12T bearing?

The QA1 NPB12T is a narrow spherical plain bearing with a 3/4 in bore diameter, 1 7/16 in outside diameter, and 0.593 in outer ring width. It uses a PTFE liner and is designed for inch-system applications. The manufacturer part number is NPB12T.

Where to buy QA1 NPB12T bearings worldwide?

You can source the QA1 NPB12T 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 time.

How to install a QA1 spherical plain bearing?

Press the bearing into a properly sized housing using a press or arbor, applying force only to the outer ring. Ensure the bore and shaft are clean and lubricated. Avoid misalignment during installation to prevent damage to the PTFE liner.
