6203-2Z Bearing Product Overview & Core Advantages
The 6203-2Z is a metric single row deep groove ball bearing featuring integral shielded protection. Engineered for high-speed operation and reliable performance, this bearing is designed to primarily accommodate radial loads. Its compact design, combined with P6 tolerance class precision and pre-lubrication, makes it an ideal component for applications demanding high rotational accuracy and long service life with minimal maintenance.
6203-2Z Bearing Model Code Explained, Specifications & Naming Convention
- 6203: Basic model number denoting a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width.
- -2Z: Signifies that the bearing is equipped with non-contact steel shields on both sides. This provides effective protection against contamination while allowing for high limiting speeds due to low friction.
6203-2Z Bearing Structural Features & Performance Benefits
Optimized for High-Speed Performance: The combination of a stainless steel cage, precision-ground chrome steel rings and balls, and non-contact shields enables a high limiting speed of 19,000 rpm.
Robust Load Capacity: With a dynamic load rating of 2237 lbf and a static load rating of 1068 lbf, this bearing offers reliable performance under significant radial loads.
Maintenance-Free Operation: The bearing is pre-lubricated with grease and sealed with 2Z shields, creating a sealed-for-life unit that is protected from contaminants and lubricant loss, ideal for applications where re-lubrication is difficult.
Precision and Reliability: Manufactured to P6 tolerance class and standard CN radial internal clearance, it ensures smooth, quiet, and precise operation, contributing to overall system accuracy.
6203-2Z Bearing Typical Application Areas
The 6203-2Z is widely used in various industrial sectors due to its versatility and reliability. Common applications include:
- Electric Motors and small machinery
- Pumps and Compressors
- Precision Power Tools
- Automotive components (e.g., alternators, starters)
- Material handling equipment and conveyor systems
