Speed (rolling bearing)

The speed of rolling bearings refers to the maximum rotational speed at which the bearing can be operated without damage occurring. The speed is usually specified in revolutions per minute (RPM) and is an important parameter when selecting a suitable bearing for a specific application. For high-speed bearings, the speed is specified separately for the lubricants oil and grease.

The maximum speed of a rolling bearing depends on various factors, including

• Bearing type and design: Different types of bearings have different limits in terms of their speed capacity. For example, angular contact ball bearings or angular contact roller bearings can often achieve higher speeds than deep groove ball bearings or cylindrical roller bearings.
• Bearing size: Smaller bearings tend to tolerate higher speeds than larger bearings, as smaller bearings have less inertia and can therefore be accelerated and decelerated more quickly.
• Lubrication: The type of lubrication and its effectiveness have a significant influence on the speed capacity of a bearing. Sufficient lubrication is crucial in order to reduce friction and wear and increase the speed.
• Operating environment: Factors such as temperature, lubricant conditions, dirt and contamination can influence the speed capacity of a bearing. Extreme operating conditions can reduce the maximum speed of a bearing.
• Mounting and alignment: Precise mounting and alignment of the bearing in the machine are important in order to avoid undesirable vibrations and axial loads that could impair the speed capacity.

When selecting a bearing for a particular application, it is important to consider the specific speed requirements and choose a bearing that meets these requirements. It is also important to keep an eye on the speed of the bearing during operation and ensure that it remains within the limits specified by the manufacturer to ensure safe and reliable operation.
