6217-2RS1NR/C3W64 Bearing Product Overview & Core Advantages
The 6217-2RS1NR/C3W64 is a single row deep groove ball bearing engineered for exceptional reliability in demanding industrial applications. This sealed bearing is distinguished by its integrated snap ring and Solid Oil lubrication system, providing a robust, long-lasting solution. Its design excels at handling high radial loads while accommodating moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards with a C3 radial internal clearance, it offers a precise fit and stable performance across a wide temperature range from -30°C to 120°C, making it a versatile and durable choice for continuous operation.
6217-2RS1NR/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
- 6217: Basic designation indicating a single row deep groove ball bearing with an 85 mm bore and 150 mm outside diameter.
- 2RS1: Signifies the bearing is sealed on both sides with contact seals, providing superior protection against contaminants and retention of lubricant.
- NR: Denotes an outer ring with a snap ring groove, facilitating secure axial location within a housing without the need for complex housing shoulders.
- C3: Indicates a greater radial internal clearance than the Normal (CN) group. This is optimal for applications with significant thermal expansion or where interference fits are used.
- W64: Identifies the bearing is pre-lubricated with Solid Oil, a polymer matrix saturated with oil. This offers advantages over grease, including no leakage, longer service life, and consistent performance in challenging environments.
6217-2RS1NR/C3W64 Bearing Structural Features & Performance Benefits
Robust Sealing & Lubrication: The combination of 2RS1 double-contact seals and W64 Solid Oil creates a virtually maintenance-free system. This effectively excludes contaminants and ensures a consistent lubricant supply, significantly enhancing bearing service life and reliability, even in dirty or wash-down conditions.
Simplified Installation & Axial Location: The integrated snap ring (NR) on the outer ring simplifies housing design and assembly. It provides secure axial location, reducing the risk of creep and simplifying the overall mechanical design.
Optimized Load & Speed Capacity: Constructed from high-grade chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 18,884 lbf and a static load rating of 13,916 lbf. Its precision construction supports a limiting speed of 4,300 rpm, making it suitable for a wide range of industrial speeds.
Thermal & Dimensional Stability: The specified C3 clearance accommodates thermal expansion from high-speed operation or interference fits, preventing premature failure due to excessive preload. The tight dimensional tolerances ensure predictable performance and ease of integration.
6217-2RS1NR/C3W64 Bearing Typical Application Areas
This bearing's combination of sealing, solid lubrication, and snap ring location makes it ideal for applications where reliability and minimal maintenance are critical. Common uses include:
- Electric Motors and Gearboxes
- Material Handling Conveyors
- Industrial Pumps and Fans
- Agricultural Machinery
- Food and Beverage Processing Equipment (where wash-downs are common)
- Various machinery requiring secured bearing location in simple housings.
