6203-ZNR

• 6203: Standard designation for a single row deep groove ball bearing with a 17 mm bore and 40 mm outside diameter.
• Z: Indicates a shielded (non-contact) seal on one side, protecting the bearing from contaminants while maintaining high-speed capability.
• NR: Signifies that the outer ring has a snap ring groove and a snap ring is fitted. This feature simplifies housing design by providing positive axial location without the need for complex housing shoulders.

Simplified Axial Location: The integrated snap ring allows for secure mounting, reducing assembly complexity and cost. The snap ring's outside diameter is 44.6 mm with a width of 1.12 mm.

Contamination Protection: The Z-shield effectively excludes larger particulate contaminants, enhancing bearing life in less-than-ideal environments without significantly increasing friction.

High-Speed Performance: The combination of a stainless steel cage, precision P0 tolerance class, and optimized CN radial internal clearance ensures stable operation at high rotational speeds, with a limiting speed of 24,000 rpm.

Robust Load Capacity: With a dynamic load rating of 2237 lbf and a static load rating of 1068 lbf, this bearing is built to handle significant radial loads.

Ready-to-Use & Maintenance-Friendly: Pre-lubricated with grease, the bearing operates reliably within a temperature range of -30°C to 120°C, making it a maintenance-free solution for many applications.

The 6203-ZNR is ideally suited for applications requiring compact design and secure mounting. Common uses include:

• Electric Motors and Gearboxes
• Automotive Components (e.g., alternators, starters)
• Industrial Fans and Blowers
• Conveyor Systems
• Agricultural Machinery
• Various machinery where efficient housing design and contamination resistance are critical.
