6302-RS1/C3MT Bearing Product Overview & Core Advantages
The 6302-RS1/C3MT is a metric single row deep groove ball bearing engineered for reliable performance in demanding applications. Its sealed construction provides robust protection against contaminants, while the optimized internal geometry ensures smooth operation and long service life. This bearing is characterized by its ability to handle significant radial loads and moderate axial loads in both directions, making it a versatile and compact solution for a wide range of industrial machinery. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers excellent value and consistent performance for general precision applications.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6302 | Basic series designation for a medium-duty, single row deep groove ball bearing with a 15mm bore, 42mm OD, and 13mm width. |
| RS1 | Indicates the presence of a synthetic rubber contact seal on one side of the bearing. This provides superior sealing effectiveness compared to non-contact shields, protecting against dust and moisture ingress. |
| C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications with significant thermal expansion, such as in electric motors, or where interference fits are used. |
| MT | Denotes that the bearing is pre-lubricated with a high-quality grease. This ensures immediate operational readiness and provides long-term lubrication for the bearing's service life under normal conditions. |
6302-RS1/C3MT Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The RS1 contact seal is molded from synthetic rubber and lightly contacts the inner ring land, creating an effective barrier against contaminants. This significantly extends bearing life in dirty or humid environments, making it a maintenance-free solution for many applications.
- Optimized Internal Geometry: The deep groove raceways and high-quality chrome steel construction (rings, balls, and cage) are engineered for high dynamic load capacity and quiet, low-vibration operation.
- Enhanced Operational Flexibility: The C3 radial internal clearance allows for stable operation under conditions that generate heat, preventing pre-load and potential seizure. This makes the bearing suitable for applications with high rotational speeds or thermal gradients.
- Ready-to-Install Convenience: Being pre-lubricated (MT), the bearing arrives ready for immediate installation, eliminating the need for initial greasing and reducing assembly time and potential for error.
6302-RS1/C3MT Bearing Typical Application Areas
The 6302-RS1/C3MT is a versatile component found in numerous industrial sectors, including:
- Electric Motors and Generators (utilizing the C3 clearance for thermal expansion)
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- Pumps and Fans
- General Industrial Machinery requiring a reliable, sealed bearing solution.
