Applications & Use Cases

The NSK 3204 B 2RS TNG is a double-row angular contact ball bearing designed for applications where both radial and axial loads must be supported simultaneously. Its compact dimensions (20 mm bore x 47 mm outer x 20.6 mm width) make it ideal for gearboxes, motors, spindles, pumps, and industrial drives that require precision, reliability, and efficient use of space.

The 2RS sealed construction prevents the ingress of dust, dirt, and moisture, ensuring consistent lubrication and reduced maintenance. The TNG cage, made from glass-fibre reinforced polyamide, offers lightweight strength and low friction during operation, making this bearing suitable for medium-speed industrial applications.

Key Features & Advantages

  • Double-row angular contact design — handles combined axial and radial loads in both directions.

  • 2RS rubber seals — provide long-term protection and minimize the risk of lubricant leakage.

  • TNG polyamide cage — offers high stability, reduced friction, and excellent temperature resistance.

  • Optimized internal clearance — ensures smooth performance and extended bearing life.

  • Compact and efficient dimensions — 20x47x20.6 mm design fits confined spaces while maintaining load capacity.

  • Maintenance-free operation — pre-lubricated and sealed for long-term reliability.
