3. Technical Description

This bearing is a four point contact ball bearing with a split inner ring, designed to support:

• Radial loads
• Axial loads in both directions

In a four point contact bearing, the ball contacts the raceways at four points, allowing one row of balls to carry axial load in both directions. This makes it a compact alternative to paired angular contact ball bearings, especially when:

• Space is limited
• Axial loads act alternately in both directions
• Combined radial and axial loads are present

Key design features:

• Split inner ring simplifies mounting and allows the bearing to accommodate axial forces in both directions with a single row of balls.
• Brass cage provides high strength, good stability at elevated temperatures, and reliable guidance of the balls.
• Open design (no seals) allows flexible lubrication with grease or oil from the surrounding system.

With normal radial clearance and standard tolerance class, this bearing is suitable for a wide range of general industrial and motion-control applications.

4. Typical Applications

• Gearboxes and compact drives
• Industrial valves and actuators
• Robotics and indexing tables
• Turntables and rotary joints
• General machinery where:
• Axial load acts in both directions
• Combined radial + axial loads must be supported in limited space

5. Key Advantages

• Four point contact design → supports axial loads in both directions with a single bearing row
• Split inner ring → compact design and efficient axial load distribution
• Brass cage → strong, stable, and suitable for higher temperatures and demanding duty
• Normal radial clearance → drop-in fit for many standard applications
• Wide temperature range (–30 to +150 °C) for industrial environments
