W6003-2Z W/MOLYKOTE G-4500 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables efficient handling of radial loads and moderate axial loads in both directions, making it versatile for various mounting configurations.
Stainless Steel Construction: Both rings and balls manufactured from stainless steel provide superior corrosion resistance, essential for applications in humid or chemically aggressive environments.
Shielded Protection: The non-contact steel shields (2Z) effectively exclude contaminants while minimizing friction, contributing to the high limiting speed of 21,000 rpm.
Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance class with CN radial clearance, ensuring smooth operation and reduced vibration in precision applications.
Advanced Lubrication: Pre-lubricated with MOLYKOTE G-4500, offering excellent performance across the entire temperature range (-30° to 120°C) and extended relubrication intervals.
