High Precision Single Row Angular Contact Ball Bearings for CNC spindles Robotics

Angular Contact Ball Bearings – High Precision, High Speed, Combined Load Capacity. Single-row, double-row and paired configurations for CNC spindles, robotica, high-speed motors and pumps. Contact angles (15°–40°) tailored for axial load or high-speed priority.

Additional Variants:

Open design – Maximum speed capability; user must apply appropriate grease or oil.

Sealed variants (2RS) – Contact rubber seals on both sides provide excellent contamination protection. Sealed angular contact bearings can extend grease life by over 1.5× compared to open designs, making them ideal for precision operations in dusty or washdown environments.

Shielded variants (Z.Z) – Non-contact metal shields for high-speed applications requiring dust protection without friction penalties.

Angular Contact Ball Bearings – Precision and Strength for Demanding Rotary Applications

Angular contact ball bearings are inherently more capable than deep groove ball bearings when it comes to supporting moderate to high axial forces while also maintaining high-speed capabilities. Whether you are designing a CNC machining center spindle, an electric motor for an industrial pump, a robotic arm joint, or an aerospace actuator, the ability to tailor your bearing’s contact angle, precision grade, cage material and preload makes angular contact ball bearings the definitive choice for machinery where performance cannot be compromised.

Caratteristiche principali:

1. Defined Contact Angles for Optimised Load-Speed Balance
The most fundamental distinguishing feature of angular contact ball bearings is the contact angle – the angle between the line connecting the ball-raceway contact points and a line perpendicular to the bearing axis. Standard contact angles (15°, 25°, 30°, 40° and even 60°) are available, with each angle offering a distinct trade-off between axial load capacity and speed capability.
2. Preload Optimisation – Zero Clearance, Maximum Stiffness
Angular contact ball bearings are almost never used singly in precision applications. Instead, they are typically preloaded – a permanent internal axial load applied to eliminate internal clearance. Preload removes all axial and radial free play, resulting in.
3. Precision Grades – From Industrial to Ultra-Premium
Angular contact ball bearings are available across a wide spectrum of precision levels, with each grade offering progressively tighter tolerances on dimensional accuracy and running accuracy.
4. Superior Combined Load Handling and Low Friction
Angular contact ball bearings are proficient in managing radial loads in both directions and axial loads in one direction (as single bearings). When arranged in pairs or double-row configurations, they can handle axial loads in both directions while maintaining excellent speed capability. Compared to deep groove ball bearings, angular contact bearings offer superior axial load capacity, lower friction coefficients at high speeds and reduced heat generation due to optimised internal geometry. The strategic disposition of the inner and outer rings prevents the contact point between the ball and raceway from aligning with the vertical centreline of the bearing, which is the key to their combined-load capability.
