Angular contact ball bearings
Key Words:
Angular contact ball bearings
Design Features of QJ 314 MA Bearing
QJ 314 MA Bearing is characterized by a unique design where a single row of balls engages with four points of contact on the raceways (two inner and two outer points). This configuration forms an angular contact that allows the bearing to support axial loads from both directions. QJ 314 MA bore dia is 70 mm. Its out dia is 150 mm. QJ 314 MA width is 35 mm. It provides a balance of load handling, space utilization, and performance.
What Benefits Can QJ 314 MA Bearing Provide?
Axial Load Handling: Capable of supporting significant axial loads in both directions, ideal for applications requiring bidirectional axial load support.
Compact Design: Combines the functionality of double-row bearings in a more compact form, saving space in assembly.
Radial Load Capacity: Efficiently handles radial loads, providing versatility in various mechanical setups.
Precision and Stability: Offers high precision and stability in operation, essential for applications requiring accurate rotational movement.
Space Efficiency: Ideal for applications with limited space, delivering robust performance without the need for larger bearing arrangements.
What Can QJ 314 MA Bearing Be Used for?
QJ 314 MA Bearing is utilized in applications that demand robust axial and radial load support within a compact design. Key uses include:
Turntables and Indexing Tables: For precise and stable rotation under combined loads.
Steering Systems: In automotive and marine applications for efficient steering control.
Industrial Machinery: In gearboxes and drives where space efficiency and load capacity are crucial.
Cranes and Hoists: Providing reliable performance under heavy loads in lifting equipment.
Rotary Tables: In machine tools for precise positioning and movement.
