Technical Advantages of Bearing 6304 C3 in High-Stress Environments

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.

Material Composition & Load Capacity Analysis

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.

NTN UltraClass 20 23.4 53 0.87

Customized Solutions for Industrial Applications

Specialized configurations for bearing 6304 Z include:
• High-temperature variants (up to 200°C continuous operation)
• Corrosion-resistant models with 3μm DLC coating
• Hybrid ceramic versions reducing electrical arcing by 78% in motor applications

Real-World Implementation Case Studies

A German automotive plant achieved 23% reduction in spindle replacements after switching to diameter bearing 6304 C3 units in CNC lathes. Field data shows:
• 94% survival rate after 15,000 operating hours
• 0.003mm average wear after 1-year continuous use
• 12% energy savings compared to ABEC-5 rated bearings

Maintenance Protocols for Extended Service Life

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:

Why Bearing 6304 C3 Dominates Precision Machinery

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.

FAQS on bearing 6304 c3

Q: What are the dimensions of bearing 6304 C3?

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.

Q: What does "C3" mean in bearing 6304 C3?

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.

Q: How does bearing 6304 C3 differ from a standard 6304 bearing?

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.

Q: Is bearing 6304 Z compatible with bearing 6304 C3?

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.

Q: What applications suit bearing 6304 C3?

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.
