Combined needle roller/angular contact ball bearings

Combined needle roller / angular contact ball bearings for radial and axial loads

Combined needle roller / angular contact ball bearings integrate a needle roller bearing and an angular contact ball bearing into a single design. Consequently, they can accommodate heavy radial loads alongside axial loads while maintaining compact dimensions and a low cross-section.

Application and characteristics

This bearing type is utilized where mounting space is constrained and standard locating bearings would occupy too much room. The needle roller component provides high radial load capacity, while the angular contact ball component enables the absorption of axial forces and stabilizes the system during higher-speed operation.

Combined needle roller / angular contact ball bearings perform exceptionally well in applications such as:

• machine tool spindles, where precision, rigidity, and compact packaging are critical,
• lead screws and feed systems,
• mechanical gearboxes and space-restricted drivetrain configurations,
• packaging machinery, industrial automation, and specialized equipment.

The distinct design of the elements facilitates matching the bearing to specific operating conditions and achieves an advantageous compromise between load capacity, rotational speed, and housing dimensions.

Key advantages

• High radial load capacity – the needle roller section effectively transmits heavy loads with a small cross-section.
• Axial load accommodation – the angular contact ball section stabilizes the system under the influence of longitudinal forces.
• Compact design – a low cross-section facilitates installation within confined spaces.
• High-speed capability – an excellent solution for high-precision drivetrain arrangements.
• Rigidity and precision – beneficial operating parameters in applications requiring accurate guidance.
