Product Description

The QA1 Narrow Spherical Plain Bearing (SKU 806LW8, MPN NPB3T) is a high misalignment spherical bearing with a 3/16 in bore diameter, 9/16 in outside diameter, and 0.218 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 NPB3T narrow spherical plain bearing is used in high-misalignment applications such as rod ends, linkages, and pivots in industrial machinery, off-highway equipment, and automation systems where angular movement and oscillating loads occur.

What are the specifications of the QA1 NPB3T bearing?

The QA1 NPB3T has a 3/16 in bore diameter, 9/16 in outside diameter, and 0.218 in outer ring width. It uses a PTFE liner material, operates in the inch system, and is designed for high-misalignment spherical bearing applications.

Where to buy the QA1 NPB3T bearing worldwide?

3G Electric supplies the QA1 NPB3T narrow spherical plain bearing worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this inch-system PTFE-lined bearing.

How to select the right QA1 spherical bearing for high misalignment?

Select a QA1 spherical bearing by matching bore diameter, outside diameter, and width to your housing and shaft. For high misalignment, confirm the bearing's misalignment angle rating and liner material—PTFE liners reduce friction and maintenance in oscillating applications.
