K17008AR0 Bearing Product Overview & Core Advantages
The K17008AR0 is a metric thin-section angular contact ball bearing engineered for applications demanding high precision and space optimization. As part of the Reali-Slim mm Metric Bearings series, its single-row design with a 30° contact angle is optimized to support significant combined loads, handling both radial and axial forces efficiently. Manufactured to ABEC-1 precision tolerances, this bearing offers reliable performance in compact envelopes, making it ideal for high-rigidity, weight-sensitive systems.
K17008AR0 Bearing Model Code Explained, Specifications & Naming Convention
The model number K17008AR0 is decoded as follows:
- K: Identifies the bearing as part of the Reali-Slim metric series.
- 17008: Specifies the nominal bore diameter (170 mm) and cross-section (8 mm width).
- A: Denotes the 30° contact angle, optimized for high axial load capacity.
- R0: Indicates standard radial internal clearance (0.0000 – 0.0005").
K17008AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides excellent resistance to combined loads, supporting a radial dynamic load rating of 1587 lbf and an axial static load rating of 3867 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore/outside diameter tolerance: -0.025mm to 0), ensuring smooth operation and accurate positioning.
- Optimized Material Selection: Components made from chrome steel (rings and balls) and a brass cage offer high strength, wear resistance, and stable performance across a temperature range of -30°C to 110°C.
- Space-Saving Design: With an ultra-thin cross-section (8 mm width) and a weight of only 0.21 kg, it maximizes performance in constrained spaces without compromising load capacity.
K17008AR0 Bearing Typical Application Areas
This bearing is suited for precision machinery and compact systems, including:
- Robotics and Automation: Joint and actuator assemblies requiring high rigidity and precise motion control.
- Aerospace & Defense: Guidance systems, control mechanisms, and instrumentation where weight and space are critical.
- Medical Equipment: Scanning devices and surgical robots demanding smooth, reliable operation under combined loads.
- Industrial Machinery: Rotary tables, indexing heads, and other precision equipment needing compact, high-capacity bearing solutions.
