KC070AR0 Bearing Product Overview & Core Advantages
The KC070AR0 is a high-performance thin-section angular contact ball bearing engineered for applications demanding exceptional precision and space optimization. This single-row bearing is specifically designed to handle significant combined loads, efficiently supporting both radial and axial forces simultaneously. Its inch-series dimensions (7" bore) and ultra-slim cross-section (0.375" width) make it an ideal solution for compact, weight-sensitive designs. Manufactured to ABEC-1 precision standards, it delivers reliable performance and high rotational accuracy in demanding industrial environments.
KC070AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KC | Indicates the Reali-Slim® series of thin-section bearings |
| 070 | Specifies the cross-section size and series |
| A | Denotes the 30° contact angle, optimized for handling combined loads |
| R0 | Specifies the radial internal clearance group (0.0000 – 0.0005") |
| Open | No seals or shields, allowing for custom lubrication solutions |
KC070AR0 Bearing Structural Features & Performance Benefits
This bearing's construction delivers distinct performance advantages:
- High Rigidity & Load Capacity: The 30° contact angle and single-row design provide excellent stiffness, enabling the bearing to handle substantial combined loads (Radial Dynamic: 1575 lbf, Axial Static: 3930 lbf).
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (Bore: -0.0010" to 0"), ensuring smooth operation and accurate positioning.
- Premium Materials: Components made from chrome steel (rings and balls) and a brass cage offer durability, corrosion resistance, and stable operation across a wide temperature range (-30°C to 110°C).
- Optimized Internal Geometry: Precision-ground raceways and controlled radial internal clearance contribute to reduced vibration and enhanced service life.
KC070AR0 Bearing Typical Application Areas
The KC070AR0 is ideally suited for applications requiring compact design and high precision, including:
- Robotics and automation systems (joints, rotary actuators)
- Aerospace components (control mechanisms, instrumentation)
- Medical equipment (imaging systems, surgical robots)
- Semiconductor manufacturing equipment (precision stages)
- Optical positioning systems and rotary tables
