Features
- High Load Capacity
- Designed to support combined radial and axial loads in both directions, making them ideal for applications with varying load demands.
- Enhanced durability due to the symmetrical design that distributes loads evenly across both rows of balls.
- Compact Design
- Combines two single-row angular contact ball bearings into one unit, reducing overall assembly space while maintaining performance.
- Suitable for installations where space constraints are critical.
- Enhanced Rigidity
- Double-row configuration increases structural rigidity, providing greater stability for precision applications.
- Sealing Options
- Available in open (unsealed), shielded (ZZ), or sealed (2RS) versions to meet diverse environmental requirements.
- Sealed versions offer added protection against dust, moisture, and contaminants, extending bearing life.
- Low Maintenance
- Pre-lubricated designs minimize maintenance requirements and downtime.
- Suitable for high-speed operations due to precision engineering and low-friction materials.
Applications
- Automotive Industry
- Commonly used in wheel hub assemblies (e.g., 5200, 5300 series bearings).
- Integral in gearboxes and drive shafts for compact and durable performance.
- Industrial Machinery
- Essential in electric motors, pumps, and compressors where compact, load-bearing components are needed.
- Suitable for high-speed machinery and heavy-duty processing lines.
- Agricultural Equipment
- Widely used in tilling, harvesting, and conveyor systems, handling dirt, vibration, and uneven load conditions.
- Aerospace and Robotics
- Ideal for lightweight, high-performance systems requiring precise motion control and high reliability.
- Material Handling Equipment
- Used in cranes, forklifts, and conveyor rollers to support heavy and multidirectional loads effectively.
- Textile Machinery
- Maintains smooth, high-speed operation in looms and spindles, supporting the dynamic load requirements.
Example Models
- 5200 Series: Known for compact size and versatility in light to medium applications.
- 5300 Series: Designed for higher load applications, providing robust performance in demanding environments.
