The 3312 RICH is a heavy-duty double row angular contact ball bearing designed to provide exceptional radial and axial load support. With its substantial dimensions of 60 x 130 x 54 mm, this bearing belongs to the 3300 series, which is characterized by a wider profile and higher load capacity than standard series units. Its internal design, featuring two rows of balls arranged in a back-to-back configuration, allows it to accommodate axial loads in both directions and makes it highly resistant to tilting moments.

This model is equipped with a high-performance polyamide cage, which offers excellent running properties, reduced noise, and lower friction compared to traditional steel cages. The open design is specifically intended for applications where the bearing is lubricated by an external oil bath or grease system within the machine housing. The normal internal clearance (CN) ensures optimal performance under standard industrial operating conditions.

Manufactured to professional engineering standards, the 3312 RICH ensures high structural stiffness and rotational precision for large-scale industrial drives and heavy machinery where stability and reliability are paramount.

Key Performance Advantages:

• High Load Capacity: The wider 3300 series design supports significantly higher forces than standard angular contact series.
• Bidirectional Axial Support: Capable of managing simultaneous thrust loads from both directions.
• High Operational Rigidity: Effectively resists tilting moments, providing stable shaft guidance.
• Advanced Polyamide Cage: Minimizes friction and heat generation for smoother high-speed rotation.
• RICH Engineering Durability: Built with high-grade steel to resist fatigue and extend service life in heavy-duty cycles.

Typical Applications:

• Large industrial centrifugal pumps and compressors.
• Heavy-duty agricultural machinery gear units.
• Industrial gearboxes and high-torque power transmission systems.
• Construction equipment and heavy manufacturing machinery.
