Significance of the minimum load
In order for bearings to operate reliably over the long term, a certain minimum load must be maintained. If the load is too low, the lubricating film in the bearing will not build up sufficiently, which can lead to slippage, uneven load distribution or vibrations.
These effects promote premature wear and can lead to bearing failure, especially in high-speed or precision-critical applications.
Influencing factors and calculation bases
The minimum load required depends on the bearing design, operating conditions, speed and lubrication. It is usually defined as a percentage of the static load rating C₀ in order to ensure a sufficient lubricating film and stable contact conditions.
In certain applications, such as pure thrust bearings or widely varying speeds, additional factors such as acceleration, moments of inertia or lubricant type may be taken into account.
Application and technical orientation
Compliance with the minimum load is an essential part of bearing design and directly influences service life, smooth running and operational reliability. SKA® provides specific guidelines for each bearing type, which serve as a technical basis for calculation and dimensioning. This information supports designers and users in safe design and ensures reliable operation even under variable operating conditions.
