How to achieve high-speed rotation performance of self-aligning ball bearings

Self-aligning ball bearings, with their unique design and structure, perform well under high-speed rotation conditions.

Advantages of spherical roller design

Reduce vibration and friction

Self-aligning ball bearings use a double-row spherical roller design, which has excellent performance under high-speed rotation conditions. Spherical rollers can evenly distribute loads and reduce local loads between rollers and raceways, thereby effectively reducing vibration and friction.

free scrollability

Each spherical roller can roll freely, ensuring that it can quickly adapt to changes in external forces during high-speed rotation. This free rolling helps maintain proper contact between rollers and raceways, reducing friction losses and improving bearing efficiency.

Matching accuracy of rollers and raceways

Precision Machining

Under high-speed rotation conditions, the matching accuracy between rollers and raceways is crucial. Self-aligning ball bearings use precision manufacturing and processing technology to ensure the matching accuracy of spherical rollers and raceways, reduce rolling resistance, and increase the speed limit of the bearing.

High quality materials

Self-aligning ball bearings made of high-quality materials can better maintain structural stability under high-speed rotation conditions. The material's high strength and wear resistance ensure the bearing's reliability under high loads and speeds.

The role of the cage

Stable roller spacing

Self-aligning ball bearings usually use cages made of annular notches and high-strength materials such as fiberglass-reinforced polyimide. The function of the cage is to stabilize the distance between the rollers and prevent the rollers from vibrating or falling off under high-speed rotation conditions.

Reduce vibration and noise

Through a properly designed cage, the bearing can reduce the impact and vibration between the rolling elements when rotating at high speed, thereby reducing the noise level and improving the smooth operation of the system.

High speed lubrication

Grease selection

Under high-speed rotation conditions, proper lubrication is a key factor to ensure the normal operation of bearings. Self-aligning ball bearings usually require the use of high-speed lubricating grease to reduce friction, dissipate heat, and maintain the operating temperature of the bearing within an appropriate range.

Lubrication method

Lubrication method is also a key factor in high-speed rotation performance. Self-aligning ball bearings usually use oil-air lubrication or oil lubrication to ensure timely and even lubrication of the bearings during high-speed operation.

load distribution uniformity

When rotating at high speed, the design of double rows of spherical rollers helps to keep the load evenly distributed between the rollers and raceways, reducing local loads and extending the service life of the bearings.
