What are Angular Contact Ball Bearings？

Angular contact Ball bearings are precision rolling element with an intentional contact geometry between the balls and raceways to carry combined loads, both radial and axial. Unlike the deep groove types, the positioning of its raceways is such that the rolling elements meet the rings at a well defined angle, with that contact angle as the main design parameter governing axial load capacity, stiffness, and dynamic behaviour.Single row angular contact bearings support axial load in one direction only and are commonly arranged back to back, face to face, or in tandem to provide bidirectional axial preload and support. Double row angular contact ball bearings combine two rows of running rollers in one unit, providing bidirectional load-carrying capability with reduced overall width to simplify mounting for many spindles and gearsets.

Features of Angular Contact Ball Bearings

Precise angular design： Contact angles from 15° to 40° are engineered to match specific radial–axial load ratios, providing the ideal balance between stiffness, speed capability, and axial load capacity.

Optimized raceway geometry：Specially contoured raceways increase the effective contact area, improving load distribution uniformity and minimizing stress concentrations during high-speed or heavy-load operation.

High performance cage technology：Bearings use high-strength composite or precision-machined cages that reduce friction, stabilize ball movement, and significantly increase the maximum speed limit.

Versatile sealing options： Offered in open, shielded, and sealed variants to protect against contaminants, retain lubrication, and ensure reliable performance in harsh or high-speed environments.

High stiffness and accuracy： Tight raceway tolerances and controlled internal clearance deliver excellent rigidity and low runout, making these bearings ideal for spindles, pumps, robotics, and precision gear systems.

Low friction and long life： Engineered for reduced heat generation, quiet operation, and extended service life through advanced materials, optimized geometry, and tailored lubrication options.

High temperature capability： Designed to operate steadily in high heat environments, with performance maintained up to +150°C (+300°F) depending on the configuration.

We Can Solve Your Problems

Enhanced Operating Efficiency：Optimized internal geometry minimizes the frictional power loss and maximizes the speed of machine, which facilitates smoother, energy-efficient electric cutting.

Improved Load Handling：The profiles of these bearings, especially on their inner and outer diameter surfaces, are mathematically designed with the ability to control various combination loads.

Increased System Rigidity：These bearings in high-speed and high-precision applications perform further, enhancing system rigidity by reducing deformation under load.

Extended Service Life：Advanced materials, precision manufacturing, and reliable sealing technologies help the bearings maintain performance in demanding environments, significantly prolonging their lifespan.

Frequently Asked Questions

Find answers to common questions about our bearings. If you don’t find what you’re looking for, please don’t hesitate to contact us.

How can you distinguish angular contact ball bearings from deep groove ball bearings?

Angular contact bearings come with a lopsided groove one side of the outer ring bulks up, making the balls hit the ring at a slant. Because of this tilt, they manage sideways forces along with push pull stress from one end only. On the flip side, deep groove types carry weight evenly around their track and deal with crosswise pressure plus some back-and forth tug on either side. You can spot the difference fast just by checking which one’s got that uneven rim.

What’s the difference between using a double-row angular contact bearing and a pair of single-row ones?

A double-row angular contact ball bearing handles thrust forces both ways in a tight setup yet gives fewer choices on angle settings. Two single row units set together can go face to face, back to back, or in line, so you tweak tension, rigidity, or load limits more freely. Single bearings cost less on their own; however, they might run uneven because of slight size mismatches.

What makes angular contact ball bearings unique?

One main thing is the angle where the balls meet the grooves this decides how forces are split between side and push pull directions. A wider angle handles more push-pull force but slows things down, whereas a narrower one lets it spin faster yet resists less sideways pressure. Because of this mix, they work well in tools like rotating shafts, transmission boxes, or fine tuned equipment that need to stay stiff and exact.

What is the function of the contact angle in angular contact ball bearings?

The contact angle sets how much axial force it can handle compared to radial force.A bigger contact angle handles more axial load yet allows slower speeds, whereas a narrower one boosts speed tolerance at the cost of load strength.Picking the right contact angle matters a lot for how well a bearing works.

How does lubrication influence angular contact ball bearing life?

Lubrication cuts down rubbing and damage where balls meet raceways, while also moving heat away.Lubrication that’s lacking or wrong causes surface wear, more shaking, also early breakdown particularly when there’s thrust force or tight clamping.
