Ball Bearing Size Chart – 16000 Series (Thin Section / Instrumental)
What Are 16000 Series Ball Bearings?
The 16000 series represents a family of thin-section, high-precision ball bearings designed for applications where space and weight are critical constraints. These radial ball bearings feature a reduced cross-section compared to standard series, making them ideal for compact automation, robotics, optical equipment, aerospace applications, and medical devices.
Engineered for precision and reliability, 16000 series bearings deliver exceptional performance in high-speed, light-duty applications. Their thin design allows engineers to optimize spatial efficiency without compromising load capacity or durability.

Medical Devices
Surgical instruments, dental drills, and diagnostic equipment benefit from the compact, high-speed characteristics of 16000 series bearings.
Compact Automation Systems
CNC machines, conveyor systems, and automated manufacturing equipment use 16000 series bearings in space-constrained designs.
16000 Series vs. 6000 Series: Key Differences
| Feature | 16000 Series | 6000 Series |
|---|---|---|
| Cross-Section | Thin / Reduced | Standard |
| Weight | Lightweight (40% reduction) | Heavier |
| Load Capacity | Light to moderate | Moderate to heavy |
| Speed Rating | Very high (up to 42,000 rpm) | High (typically 12,000–20,000 rpm) |
| Typical Use | Precision, compact, high-speed | General purpose, standard duty |
Frequently Asked Questions
A: Both 16000 and 5000 series are thin-section designs, but 16000 series offers different bore and outer diameter combinations, optimized for specific applications where 5000 series may not fit. Consult detailed dimensional datasheets to select the best fit for your application.
A: At speeds above 30,000 rpm, use synthetic lubricants or oil-air lubrication systems. Grease-lubricated designs are suitable for lower speeds. Always follow the bearing manufacturer's lubrication guidelines for your specific speed and temperature environment.
A: 16000 series are radial ball bearings, primarily designed for radial loads. For combined radial and axial loads, verify load ratings with the manufacturer or consider paired/tandem configurations for axial support.
A: Housing bore and shaft tolerances must match the bearing's bore and outer diameter specifications. Standard tolerances are typically ISO k5 (shaft) and k6 (housing). Refer to ISO 286 and your bearing supplier's tolerance guidelines for precise specifications.
A: Yes, 16000 series bearings are available in open, shielded (RS), and sealed (2RS) configurations. Sealed versions provide better contamination protection; open designs allow easier lubrication access. Choose based on your operating environment.
