Product Overview

The 3204-2RS (equivalent to 5204-2RS) is a high-precision double-row angular contact ball bearing engineered to accommodate combined radial and bidirectional axial loads within a compact envelope. Equipped with dual nitrile rubber (NBR) contact seals, it effectively prevents grease leakage while sealing out dust, moisture, and fine particulate contaminants.

Manufactured from premium vacuum-degassed GCr15 bearing steel and heat-treated for dimensional stability, this bearing provides high rotational rigidity, low operating vibration, and an extended service life in demanding industrial drive assemblies.

Key Features

Bidirectional Axial Load Capacity: The dual raceway geometry delivers high rigidity and supports heavy combined radial forces and thrust loads from both directions.
Effective 2RS Contamination Defense: Contact NBR seals maintain lubricant retention and guard internal rolling elements from water splash, debris, and abrasive dust.
Optimized Running Accuracy: Precision-ground raceways ensure low noise output, minimal running friction torque, and steady thermal equilibrium at high speeds.
Plug-and-Play Maintenance Free: Factory pre-greased for ready-to-install implementation with zero initial greasing required.

Applications

Industrial pumps, centrifugal blowers, and compressor drives
Automotive gearboxes, wheel hubs, and steering mechanisms
Agricultural equipment, conveyor pulleys, and sorting machinery
Electric motors, gearboxes, speed reducers, and CNC rotary tables
Packaging and textile machinery drive shafts
