6304TN Bearing Structural Features & Performance Benefits
Optimized Cage Design: The Nylon cage provides superior guidance for the balls while reducing friction and enabling higher rotational speeds. This material offers excellent strength-to-weight ratio and operates quietly across the entire temperature range.
Precision Engineering: Manufactured with chrome steel rings and balls, this bearing achieves ABEC 1 precision class with tight dimensional tolerances. The deep groove raceway geometry enables efficient handling of radial loads up to 3574 lbf while accommodating moderate axial loads in both directions.
High-Speed Capability: With a limiting speed of 14,000 rpm, this bearing excels in high-velocity applications. The open design allows for optimal lubrication management and heat dissipation, contributing to stable performance under demanding conditions.
Standard Clearance: The CN radial clearance provides balanced performance for most industrial applications, ensuring proper operation across typical temperature variations and fit conditions.
