6209-2Z/C3WT Bearing Product Overview & Core Advantages
The 6209-2Z/C3WT is a metric single row deep groove ball bearing designed for exceptional performance in demanding applications. This bearing features integrated shields (2Z) for effective contamination protection and is manufactured with C3 radial internal clearance for optimal operation under thermal expansion conditions. Its robust chrome steel construction ensures high durability and reliable radial load capacity, making it an ideal solution for industrial machinery requiring consistent performance and extended service life.
6209-2Z/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6209 | Basic designation: Deep Groove Ball Bearing, 45mm bore, 85mm OD, 19mm width |
| 2Z | Bearing with steel shields on both sides providing effective sealing against contaminants |
| C3 | Greater than normal radial internal clearance for applications with thermal expansion or shaft misalignment |
| WT | No lubrication (without grease) |
6209-2Z/C3WT Bearing Structural Features & Performance Benefits
Optimized Deep Groove Design: The raceway geometry enables smooth operation and efficient radial load distribution, with a dynamic load rating of 7,351 lbf and static load rating of 4,564 lbf.
Enhanced Protection System: Double-sided steel shields (2Z designation) effectively prevent contamination ingress while maintaining low friction operation, extending bearing service life in harsh environments.
Thermal Compensation Capability: The C3 internal clearance accommodates thermal expansion in applications with elevated operating temperatures or where interference fits are used, preventing premature failure.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class with precise dimensional control (bore tolerance: -0.012mm to 0, OD tolerance: -0.015mm to 0) ensuring consistent performance and easy installation.
High-Speed Capability: With a limiting speed of 7,700 rpm, this bearing supports demanding rotational requirements across various industrial applications.
