KB035AR0 Bearing Product Overview & Core Advantages
The KB035AR0 is a high-precision thin section angular contact ball bearing designed for applications requiring exceptional space efficiency and high performance. This single row bearing features a 30° contact angle, enabling it to support significant combined loads, including both radial and axial loads in one direction. Manufactured to ABEC-1 precision standards, it delivers reliable operation and high rotational accuracy. Its open design and lubricated construction make it suitable for high-speed applications where minimal friction and precise motion control are critical.
KB035AR0 Bearing Model Code Explained, Specifications & Naming Convention
- KB: Indicates the Reali-Slim® bearing series from Kaydon.
- 035: Represents the bore diameter in inches (3.5").
- A: Denotes the contact angle of 30°, optimized for handling combined loads.
- R: Signifies the internal radial clearance specification.
- 0: Indicates a standard open bearing design without seals or shields.
KB035AR0 Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its specific construction. The single row design with a 30° contact angle provides excellent stiffness and high thrust capacity. The use of a brass cage ensures stable operation at high speeds and reduces wear. Manufactured from chrome steel for both rings and balls, it offers high durability and a long service life. The thin cross-section (bearing dimensions: 3.5" bore x 4.125" OD x 0.3125" width) allows for compact and lightweight machinery designs without sacrificing load capacity (Radial Dynamic: 801 lbf, Axial Static: 1930 lbf). The specified radial internal clearance ensures optimal performance under operational temperatures.
KB035AR0 Bearing Typical Application Areas
The KB035AR0 thin section bearing is ideally suited for a variety of demanding applications, including:
- Robotics and automation arms
- Aerospace control mechanisms and actuation systems
- Medical equipment such as MRI and CT scanners
- Semiconductor manufacturing equipment
- Precision rotary tables and indexing heads
