71802 CD/P4DGB Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to P4 tolerance class with tight dimensional control (bore/OD tolerance: -0.004mm to 0), ensuring exceptional running accuracy and minimal vibration in precision applications.
Optimized Contact Design: The 15° contact angle provides optimal balance between radial and axial load capacity, making it suitable for applications requiring combined load support.
Advanced Cage Technology: The phenolic resin cage offers excellent strength-to-weight ratio, reduced friction, and superior performance at high speeds (limiting speed: 95,000 rpm).
Universal Matching Capability: As a Universal Matchable (SU) bearing, it can be paired with another identical bearing in various configurations (back-to-back, face-to-face, or tandem) to meet specific application requirements.
Premium Material Selection: Both rings and balls are manufactured from chrome steel, providing high hardness, wear resistance, and long service life under demanding conditions.
