| Suffix / Prefix | Technical Meaning | Significance & Advantage |
|---|---|---|
| MA | Brass Cage | Indicates a machined brass cage, offering high strength, excellent guidance, and suitability for high-speed applications and demanding operating conditions. |
| (Implied by spec) | P6 Tolerance | Denotes a tolerance class tighter than standard, resulting in reduced runout and vibration for high-precision applications. |
| (Implied by spec) | CN Clearance | Specifies the standard radial internal clearance group, suitable for most common operating conditions. |
16068 MA Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to a P6 tolerance class with strict dimensional controls on the bore diameter (340 mm) and outside diameter (520 mm), this bearing ensures precise shaft positioning and minimal deflection under load.
- Robust Load Capacity: With a high radial dynamic load rating of 77559 lbf and a radial static load rating of 116901 lbf, it is built to handle significant radial forces in heavy-duty machinery.
- Optimized High-Speed Capability: The combination of the machined brass (MA) cage, high-grade chrome steel components, and open design contributes to a stable limiting speed of 1,500 rpm.
- Durability and Corrosion Resistance: The stainless steel cage provides excellent resistance to corrosion and high temperatures, enhancing the bearing's longevity in challenging environments.
- Application Flexibility: The open seal type allows for the use of various lubrication systems, giving engineers flexibility in maintenance planning. Its wide temperature range (-30°C to 120°C) ensures performance across diverse operating conditions.
16068 MA Bearing Typical Application Areas
This bearing is ideally suited for applications requiring high precision and robust radial load capacity. Key industries and machinery include:
- Industrial Gearboxes and Transmissions
