Features
1. Uniform-section design: KC series bearings have equal dimensions in both radial and axial sections. This design enables the bearings to have excellent adaptability in situations with strict size restrictions. For example, they can be used in fields with extremely high size requirements such as robot joints and aerospace high-precision equipment.
2. Ultra-thin wall: The bearing has a thin wall and light weight, but has strong load-bearing capacity and high precision. This design achieves miniaturization and lightweight of the product, and is particularly suitable for equipment with strict requirements on installation space.
3. High strength and low friction: The manufacturing material is usually made of high-quality steel, which can effectively reduce the friction and energy loss of mechanical transmission devices and improve mechanical efficiency.
Types and configurations
KA series uniform-section ultra-thin-wall bearings include a variety of types, such as four-point contact, radial contact, angular contact, etc. These different types of bearings are suitable for different applications and load conditions. For example, angular contact bearings can support higher radial and axial loads, while four-point contact bearings are particularly suitable for situations where torsional axial loads need to be supported.
