Scheerer bearings are high-precision, low-friction bearings designed for demanding applications in various industries, including aerospace, medical, and automation. They offer exceptional accuracy, durability, and load-carrying capacity, making them an ideal choice for critical engineering systems.
Scheerer bearings are typically made of bearing steel hardened to Rockwell hardness 60-62 HRC. They consist of an outer ring, an inner ring, rolling elements, and a cage. The rolling elements can be balls, rollers, or needles, depending on the specific application.
Components of a Scheerer Bearing:
Component | Description |
---|---|
Outer ring | Supports the load and transmits it to the housing |
Inner ring | Rotates with the shaft and supports the load |
Rolling elements | Balls, rollers, or needles that roll between the rings, reducing friction |
Cage | Separates and retains the rolling elements |
Scheerer bearings come in various types, each designed for specific applications. Common types include:
