6217-2RS1/C3W64 Bearing Product Overview & Core Advantages
The 6217-2RS1/C3W64 is a single row deep groove ball bearing engineered for high performance and reliability in demanding applications. Its sealed design and Solid Oil lubrication provide exceptional protection against contamination and ensure long-term, maintenance-free operation. This bearing is characterized by its ability to handle significant radial loads and moderate axial loads in both directions, making it a versatile and robust solution for a wide range of industrial machinery. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers consistent precision and dependable performance.
6217-2RS1/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
- 6217: Basic designation indicating a single row deep groove ball bearing with an 85mm bore and 150mm outside diameter.
- 2RS1: Signifies that the bearing is fitted with two rubber contact seals (RS1 type) on both sides, offering superior protection against dust and moisture ingress.
- C3: Denotes a greater radial internal clearance than the Normal (CN) group. This is ideal for applications with significant thermal expansion or where interference fits are used.
- W64: Indicates the bearing is pre-lubricated with Solid Oil, a polymer matrix saturated with lubricant. This provides a long service life, reduces maintenance, and is effective across a wide temperature range.
6217-2RS1/C3W64 Bearing Structural Features & Performance Benefits
The performance of the 6217-2RS1/C3W64 is a direct result of its specific construction:
- High Load Capacity & Rigidity: The robust single row deep groove raceway geometry, combined with high-grade chrome steel rings and balls, provides a high dynamic load rating of 18884 lbf and static load rating of 13916 lbf, ensuring stable operation under heavy loads.
- Maintenance-Free & Contamination Resistant: The two RS1 rubber contact seals effectively shield the internal components from contaminants. Combined with the integrated Solid Oil (W64) lubrication, this design eliminates the need for re-lubrication, reduces downtime, and extends bearing service life.
- Optimized for Thermal Stability: The C3 radial internal clearance accommodates dimensional changes caused by thermal expansion in the shaft and housing, preventing preload and potential seizure, which is critical for consistent performance.
- Reliable High-Speed Operation: The precision-ground components and stable Solid Oil lubrication enable a limiting speed of 4300 rpm, making it suitable for a variety of high-speed applications.
6217-2RS1/C3W64 Bearing Typical Application Areas
This bearing's combination of high load capacity, sealed construction, and maintenance-free operation makes it ideal for numerous industrial sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Compressors
- General Industrial Machinery requiring robust and reliable rotary support.
