Ball bearings are simple but powerful components that minimize friction in rotational applications ranging from industrial machinery to office equipment. Spherical ball bearings have only minimal contact with their containing races, allowing them to transfer radial or axial loads with rapid, fluid motion. A variety of housing shapes and lubrication options improve versatility while promoting performance across a long working life.
Miniature Bearings
Miniature bearings are defined by their very small rolling elements, with bore diameters no larger than 10 mm (0.3937″). Bearings of this size enable high-speed rotation with minimal noise or vibration. Thanks to their excellent frictional torque performance, these bearings are well-suited to a range of high-speed motor applications, including (but not limited to):
We supply durable miniature bearing in both Metric and Inch designations for maximum compatibility across applications.
- Fan motors
- Spindle motors
- Stepping motors
- Rotary encoders
- Dental handpieces
- Drills
- Medical devices
- Fan Motors
Flanged Bearings
Flanged bearings are categorized based on their shape rather than the size of their rollers. Designed for applications with challenging positioning requirements, flange bearings feature a small lip along their outer ring that helps to mount, position, and lock the component in place. This feature is especially important in high-vibration environments where components may otherwise be prone to slippage. Some common uses for flanged bearings include:
- Scanner motors
- Stepping motors
- Rotary encoders
- Card readers
- And other applications
Thrust Bearings
Thrust bearings are designed to withstand both thrust loads and axial loads, but not radial loads. They can rotate at high speeds and support large axial loads during operation. With typical use cases including (but not limited to):
- Main axis of machining tools
- Jacks
- Turntables for vertical turning machines
Selecting the Right Bearings for Your Application
Selecting the right bearing for your application requires a careful consideration of rotating speed, load conditions and temperature in order to prevent premature bearing failure.
