61910-2RZ/C3GJN Bearing Product Overview & Core Advantages
The 61910-2RZ/C3GJN is a metric single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity and precise operation. Featuring integrated seals (2RZ) and optimized C3 radial internal clearance, this bearing delivers exceptional protection against contamination while maintaining stable performance under varying thermal conditions. Its compact design with a 50mm bore and 12mm width makes it ideal for space-constrained applications where consistent rotational accuracy and long service life are critical requirements.
61910-2RZ/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| 2RZ | Non-contact rubber seals on both sides | Superior contamination protection with minimal friction increase |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature applications |
| GJN | Polyurea grease with temperature range -30°C to +150°C | Extended lubrication intervals and reliable performance across wide temperature range |
61910-2RZ/C3GJN Bearing Structural Features & Performance Benefits
Optimized Sealing System: The 2RZ non-contact rubber seals provide excellent protection against dust, moisture, and other contaminants while maintaining low operating torque, making this bearing suitable for applications requiring both contamination resistance and energy efficiency.
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class with chrome steel rings, balls, and cage, this bearing ensures consistent running accuracy and reduced vibration during operation.
Enhanced Load Capacity: With a dynamic load rating of 3282 lbf and static load rating of 2653 lbf, this deep groove ball bearing delivers reliable performance under significant radial loads while maintaining dimensional stability.
Thermal Performance: The C3 radial clearance accommodates differential thermal expansion between bearing components and housing, preventing premature failure in applications with operating temperatures up to 120°C.
61910-2RZ/C3GJN Bearing Typical Application Areas
- Electric Motors: Ideal for small to medium-sized motors requiring sealed bearings with reliable performance
- Industrial Gearboxes: Suitable for auxiliary shafts and reduction gears where contamination protection is essential
- Material Handling Equipment: Conveyor rollers, pulleys, and other components requiring sealed bearing solutions
- Agricultural Machinery: Implement drives and auxiliary systems operating in harsh environments
- HVAC Systems: Blower motors and fan assemblies requiring long-term, maintenance-free operation
