Design and Construction

The 6200-2Z features a single row deep groove configuration, the most commonly used bearing type due to its simplicity, versatility, and reliability. It is constructed with:

• High-grade bearing steel for the inner and outer rings
• Steel balls for smooth rotation and load distribution
• A sheet metal cage to maintain ball spacing and reduce friction
• Non-contact metal shields (2Z) on both sides to protect against contaminants

These shields are designed to retain the factory-applied grease while preventing the ingress of dust, dirt, and moisture, ensuring long-term, maintenance-free operation.

Performance Features

1. High-Speed Capability

With a reference speed of 56,000 rpm and a limiting speed of 28,000 rpm, the 6200-2Z is ideal for high-speed applications. The low-friction design ensures smooth operation with minimal heat generation, enhancing energy efficiency and reducing wear.

2. Dual Shield Protection

The 2Z metal shields on both sides offer excellent protection against external contaminants while retaining the internal lubricant. This design significantly extends the bearing’s service life and reduces the need for relubrication.

3. Versatile Load Handling

This bearing can accommodate radial loads and moderate axial loads in both directions. Its deep groove geometry allows for precise alignment and stable performance under varying load conditions.

4. Robust and Durable

Manufactured from high-quality bearing steel, the 6200-2Z offers excellent resistance to wear, fatigue, and corrosion. Its robust construction ensures consistent performance even in demanding environments.

5. Maintenance-Free Operation

Pre-lubricated and sealed for life, the 6200-2Z is designed for maintenance-free operation in most applications. This reduces downtime and operational costs, making it a cost-effective solution for long-term use.
