How to Choose the Right Bearing
Selecting the correct ball bearing involves several critical parameters:
1Application
Bearings are utilized across various fields including Agriculture, Industry (assembly lines), Machines (robotics), Vehicles (cars, cycles), and Domestic appliances.
2Speed of Rotation
Ball bearings support high speeds and reduced loads. Speed limits are determined by operating temperature, bearing type, load size, and lubrication conditions.
3Supported Load
- Basic Dynamic Load: The maximum permissible load for a nominal life of 1 million revolutions.
- Static Charge: The load applied to a stationary bearing, relating to contact stress.
4Bearing Life & Fatigue
Life is defined by the number of revolutions or hours before signs of fatigue appear. The nominal fatigue life (L10) represents a 90% reliability standard.
5Tolerances
Tolerances are standardized internationally via ISO. Standard bearings are typically manufactured in the P0 tolerance class.
How to Measure a Bearing
Step 1: Inside Diameter (Bore) - Place the bearing on a grid, justify the inside edge, and mark the inner contour to measure the diameter.
Step 2: Outside Diameter - Mark the outline of the outer ring using a fine-point pencil on a measuring grid.
Step 3: Thickness - Place the bearing on its edge on the grid and draw the outer contour to measure the width.
