61800-2Z/C3 Bearing Product Overview & Core Advantages
The 61800-2Z/C3 is a miniature metric single row deep groove ball bearing featuring integral shielded protection and a C3 radial internal clearance. Engineered for compact applications requiring reliable performance, this bearing excels in handling radial loads with high efficiency. Its shielded design provides effective contamination exclusion while maintaining low friction, making it ideal for applications demanding long service life and minimal maintenance in constrained spaces.
61800-2Z/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| 61800 | Series designation for miniature deep groove ball bearings | Compact design with 10mm bore, 19mm OD, 5mm width |
| 2Z | Non-contact steel shields on both sides | Effective dust protection without significant speed reduction |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature applications |
61800-2Z/C3 Bearing Structural Features & Performance Benefits
Optimized Miniature Design: The single row deep groove raceway and precision-ground chrome steel components deliver smooth operation and consistent performance in compact assemblies. The shielded construction effectively excludes contaminants while maintaining low torque characteristics.
Enhanced Load Capacity: With a dynamic load rating of 387 lbf and static load rating of 187 lbf, this bearing provides reliable performance in radial load applications. The deep groove geometry enables it to handle moderate combined loads when properly mounted.
High-Speed Capability: The ABEC 1 | ISO P0 tolerance class ensures consistent operation at speeds up to 48,000 rpm. The non-contact shields minimize friction while providing essential protection.
Thermal Stability: The C3 clearance accommodates differential thermal expansion between shaft and housing, making it suitable for applications with operating temperatures ranging from -30°C to 120°C.
