6002-2RSL TN9 HC5C3WT Bearing Product Overview & Core Advantages
The 6002-2RSL TN9 HC5C3WT is a sealed single row deep groove ball bearing engineered for high-performance applications. Its core advantages stem from its hybrid ceramic construction, featuring Silicon Nitride (Si3N4) balls for superior speed capability and reduced friction. The combination of a nylon cage (TN9) and robust sealing (2RSL) ensures reliable operation under radial loads with extended service life, making it an ideal choice for applications demanding precision and durability.
Model Code Breakdown
- 6002: Basic designation for a single row deep groove ball bearing with a 15mm bore and 32mm outside diameter.
- 2RSL: Indicates contact seals on both sides, providing effective protection against contaminants and retaining lubricant.
- TN9: Denotes a glass fiber reinforced nylon cage, contributing to low weight, quiet operation, and suitability for high speeds.
- HC5: Signifies the use of Hybrid Ceramic components, specifically Silicon Nitride balls.
- C3: Specifies a greater radial internal clearance than normal, suitable for applications with thermal expansion or where interference fits are used.
- WT: Indicates the bearing is supplied without lubrication (None).
6002-2RSL TN9 HC5C3WT Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The use of Silicon Nitride balls significantly reduces friction and heat generation, enabling higher limiting speeds (23,000 rpm) and improved efficiency compared to all-steel bearings. This material also offers excellent electrical insulation and corrosion resistance.
Reinforced Nylon Cage: The TN9 cage provides high strength-to-weight ratio, excellent acceleration characteristics, and dampens vibration for quieter operation.
Robust Sealing: The 2RSL low-friction contact seals effectively shield the bearing interior from dust, moisture, and other contaminants, enhancing reliability in challenging environments.
Optimized Internal Clearance: The C3 radial internal clearance accommodates thermal expansion in high-speed or high-temperature applications, ensuring stable performance.
