A ball bearing is a type of rolling-element bearing that uses balls to reduce friction between moving parts and support radial and axial loads. It is one of the most common types of bearings used in various applications, from machinery and vehicles to household appliances.
Here’s a general description of a ball bearing:
- Outer Ring: This is the outermost part of the ball bearing. It serves as the primary support structure and contains the inner components.
- Inner Ring: This is the innermost part of the bearing that fits onto the rotating shaft.
- Balls: The balls are the rolling elements within the bearing that facilitate smooth rotation between the inner and outer rings. These balls are typically made of steel, ceramic, or other materials with good hardness and durability.
- Cage or Retainer: The cage holds and separates the balls, ensuring they are evenly spaced and do not collide during operation. It also allows for continuous rotation while maintaining the balls’ relative positions.
- Lubrication: Ball bearings require lubrication to reduce friction and heat generation during operation. Various lubricants, such as grease or oil, are used to ensure smooth functioning and extend the bearing’s life.
Ball bearings are known for their efficiency in reducing friction, making them ideal for high-speed applications. They come in various designs, including single-row, double-row, and thrust ball bearings, each designed to handle specific loads and operating conditions.
It’s important to note that “FLT” in the context of a ball bearing description might refer to a specific brand or manufacturer, but without additional context, I cannot provide more specific details. Different manufacturers may offer various features or specifications for their ball bearings, so it’s essential to refer to the manufacturer’s documentation for precise information about a particular FLT ball bearing.
