Product Introduction
The 6204 deep groove ball bearing is one of the most widely used rolling bearings. It supports both radial load and a small amount of axial load, suitable for high-speed running conditions. We supply 3 versions: open type, ZZ double metal shielded type, and 2RS double rubber sealed type to meet different working environment requirements. Manufactured with high-quality bearing steel, this bearing delivers stable rotation performance, low noise and long service life for general machinery and equipment.
Product Features
1. Multiple seal options: OPEN (no seal), ZZ (double iron shields), 2RS (double rubber seals) available for selection
2. Made of high carbon chromium bearing steel (GCr15), good hardness and wear resistance
3. Low friction torque, smooth rotation, low running noise
4. Can bear radial load and limited bidirectional axial load simultaneously
5. Simple structure, easy installation and maintenance
6. Strict tolerance control, consistent quality for bulk OEM orders
Product Functions
- Mainly bear radial loads, and accept moderate axial loads in both directions
- Reduce friction coefficient between rotating shaft and housing
- Support rotating components to keep stable operation at high speed
- Prevent dust, debris or grease leakage (ZZ / 2RS sealed types)
- Maintain mechanical running accuracy and extend equipment service cycle
