With a specialized patented sealing design, this bearing effectively resists environmental contaminants and moisture, significantly extending the service life of your equipment.

Technical Specifications

Key Product Advantages

• Premium Material Selection: We utilize high-purity bearing steel that undergoes rigorous heat treatment. This results in superior hardness and wear resistance, allowing the 61900-2Z to handle radial loads with consistent precision.
• Advanced Sealing Technology: The 2Z metal shields provide a robust barrier against dust and debris. This “shielded for life” design ensures that the internal lubricant remains clean, reducing maintenance requirements in sensitive environments.
• Optimized Internal Geometry: Our manufacturing process focuses on ultra-fine raceway finishing. This reduces torque and vibration, making it a perfect fit for high-speed dental tools, beauty instruments, and precision motors.
• Customization and R and D Support: As a manufacturer specializing in non-standard and high-precision bearings, we provide tailored solutions. We can adjust clearance, lubrication types, and tolerances to meet the specific needs of your machinery.

Industrial Applications

The versatility of the 61900-2Z makes it a staple in various high-tech industries:

1. Stepper Motors: Ensures high positional accuracy and smooth stepping transitions.
2. Beauty and Medical Instruments: Ideal for eccentric blocks and rotating components where hygiene and low noise are critical.
3. Textile Machinery: Provides reliable support for high-speed spindles and rollers.
4. Engineering Robotics: Offers compact load support for articulated joints and small drive systems.

Frequently Asked Questions

1. What are the benefits of the 2Z metal shields compared to open bearings?
The 2Z shields protect the bearing from large particles and retain the factory-filled grease. This makes them suitable for environments where external lubrication is difficult or where dust might interfere with performance.

2. Can the 61900-2Z bearing handle axial loads?
While primarily designed for radial loads, deep groove ball bearings can support a degree of axial load in both directions. However, for high axial load requirements, we recommend consulting our technical team for a specialized solution.

3. What makes FTM bearings a reliable alternative to international brands?
With 30 years of experience, FTM focuses on high-precision import substitution. We use the same high-grade materials and precision grinding processes as top-tier global brands but offer more flexible customization and faster lead times.

4. Is this bearing pre-lubricated?
Yes, our 61900-2Z bearings are pre-filled with high-quality specialized grease designed for high-speed stability and wide temperature ranges, ensuring they are ready for immediate installation.

5. How does the 70,000 r/min limit affect the bearing life?
The grease lubrication limit of 70,000 r/min represents the safe operating ceiling. Operating at these high speeds is possible due to our precision-engineered rolling elements which minimize heat generation and centrifugal stress.
