QJ 1092 N2MA Bearing Product Overview & Core Advantages
The QJ 1092 N2MA is a Four-Point Contact Ball Bearing designed for exceptional performance in demanding applications. This metric single row bearing is engineered to simultaneously withstand combined radial and axial loads from both directions, making it an ideal solution for compact, high-rigidity designs. Its P6 (ABEC-3) tolerance class ensures high running accuracy, while its robust construction provides reliable operation in a wide temperature range from -30°C to 110°C.
QJ 1092 N2MA Bearing Model Code Explained, Specifications & Naming Convention
- QJ: Denotes the four-point contact ball bearing series
- 1092: Indicates the specific size series and bore diameter
- N2: Signifies the bearing is lubricated with grease
- MA: Represents the brass cage material
QJ 1092 N2MA Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The unique raceway geometry allows the bearing to handle combined loads efficiently, providing axial rigidity in both directions while maintaining compact dimensions.
High Load Capacity: With a dynamic radial load rating of 234,000 lbf and static radial load rating of 596,250 lbf, this bearing offers exceptional durability under heavy operating conditions.
Precision Performance: Manufactured to P6 tolerance class with optimized internal clearances, ensuring smooth operation and minimal vibration for precision applications.
Brass Cage Construction: The MA designation indicates a machined brass cage that provides excellent strength, temperature resistance, and reliable performance at the limiting speed of 1,300 rpm.
