6203-2RSJEM/LHT23 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing delivers high strength and durability. It is rated for a radial dynamic load of 2147 lbf and a radial static load of 1079 lbf, making it suitable for applications with significant radial forces.
- Effective Sealing for Long Service Life: The integral double-contact rubber seals (2RS) effectively shield the internal components from dust, moisture, and other contaminants. This design preserves the bearing's integrity and contributes to its maintenance-free characteristic over a wide temperature range of -30°C to 120°C.
- Precision & High-Speed Capability: Built to ABEC 1 precision class with a standard CN radial internal clearance, it ensures smooth and quiet operation. The optimized design supports a limiting speed of 17,000 rpm, catering to a variety of high-speed applications.
- Lightweight & Compact Design: With a total weight of just 65 grams, the bearing minimizes rotational inertia, contributing to energy efficiency and rapid start-up in dynamic systems.
