63804 2rs Bearing Structural Features & Performance Benefits
Deep Groove Raceway Design: The optimized raceway geometry enables smooth operation under radial dynamic loads up to 904 lbf, while accommodating moderate axial loads in both directions.
Sealed Construction: Double rubber seals effectively exclude contaminants while retaining lubricant, significantly extending bearing service life in harsh environments.
Precision Manufacturing: Manufactured to ABEC-1 tolerance class with chrome steel rings and balls ensures consistent performance and dimensional stability.
Stainless Steel Cage: The stainless steel cage provides excellent corrosion resistance and maintains ball alignment at speeds up to 25,000 rpm.
Radial Internal Clearance: Standard C0 clearance (0.006mm to 0.020mm) ensures proper fit and thermal expansion management in most applications.
