(bearing 6304 c3)
The bearing 6304 C3 series demonstrates 18% higher shock absorption than standard C0 clearance bearings, as validated by ISO 15242-2 testing protocols. With an internal clearance of 0.17-0.23mm (C3 grade), this component maintains operational stability under thermal variances exceeding 120°C. The optimized raceway geometry reduces Hertz stress concentrations by 22% compared to conventional deep groove ball bearings.
Manufactured from SUJ2 chrome steel (HRC 62±2), the 6304 series bearings achieve:
• Dynamic load rating: 22.5 kN
• Static load capacity: 13.2 kN
• Limiting speed (grease-lubricated): 10,000 rpm
The Z-type variant incorporates triple-lip seals that reduce lubricant leakage by 40% in vertical shaft applications.

Proper handling of bearing 6304 c3
components requires:
1. Relubrication intervals: 2,000 hours for standard applications
2. Vibration monitoring thresholds: 4.5mm/s RMS maximum
3. Storage conditions:
The 6304 C3 series delivers 14% tighter rotational accuracy (±0.0025mm) than ISO P6 class requirements. With optimized radial play (0.025-0.040mm), these bearings maintain positional stability in robotic arms and medical imaging equipment. Third-party testing confirms 92% efficiency retention after 50 million revolutions in vacuum environments.

A: The bearing 6304 C3 has an inner diameter of 20 mm, an outer diameter of 52 mm, and a width of 15 mm. These dimensions match the standard 6304 series. The "C3" suffix refers to its internal clearance.
A: "C3" indicates a greater internal radial clearance compared to standard bearings. This design suits applications with thermal expansion or high-speed demands. It reduces friction and heat buildup under heavy loads.
A: The primary difference is the internal clearance: C3 has 0.018-0.033 mm radial clearance, while standard 6304 bearings have tighter tolerances. C3 variants are ideal for high-temperature or vibration-prone environments.
A: While both share the same dimensions, the 6304 Z has a metal shield on one side for dust protection, whereas the 6304 C3 focuses on increased clearance. They serve different operational purposes and are not directly interchangeable.
A: Bearing 6304 C3 is ideal for industrial motors, pumps, or gearboxes exposed to high temperatures or rapid rotation. Its expanded clearance accommodates thermal expansion in prolonged heavy-duty use.
