Core Product Specifications

1. Housing Materials & Coatings

• Materials:
  • Aluminum: Lightweight (60% lighter than steel) with excellent thermal conductivity. Ideal for weight-sensitive applications like robotics.
  • Steel: High load and impact resistance for heavy machinery (e.g., conveyor systems).
  • Stainless Steel: Corrosion-resistant solution for food processing, marine, or chemical industries (AISI 304/316 standards).
• Coatings:
  • Uncoated: Economical option for controlled indoor environments.
  • Burnished: Enhanced surface hardness via precision polishing.
  • Anodized (Aluminum only): 3x improved wear resistance and dielectric protection.
  • Nickel-Plated: Superior corrosion barrier (salt surface.

2. Ball Bearing Engineering

• Materials:
  • Chrome Steel (GCr15): High dynamic load rating (up to 15kN) for automotive/industrial use.
  • Stainless Steel (AISI 440C): Acid/alkali resistance with non-magnetic properties.
• Types:
  • Deep Groove Ball Bearings: Handle radial and axial loads in any direction. Quiet operation (≤20dB) for electric motors.
  • Angular Contact Ball Bearings: Optimized for combined loads at specific contact angles (15°/25°/40°).

3. Housing Geometry & Mounting Systems

| Housing Type | Key Features | Typical Applications | |--------------------|-----------------------------------------------------------------------------|-----------------------------------| | Compact Flange | Space-saving design with through-hole mounting | Packaging machinery, CNC spindles | | Round Flange | 360° uniform load distribution | Pumps, fans | | Square Flange | Anti-rotation stability with 4-bolt fixation | Agricultural equipment compatibility (±0.1mm precision) | Automation rails | | T-Shape/L-Shape| Multi-directional mounting in confined spaces | Textile machinery | | Block Shape | Maximum vibration damping (up to 40% reduction) | Compressors, generators |

4. Technical Parameters

• Inner Diameter Range: 3mm–50mm (covers M3–M50 shaft sizes)
• Retention Systems: Circlip-secured bearings for easy maintenance
• Sealing Options: Integrated shields or seals (IP54–IP68 protection)

Why Choose Our Bearing Units?

• Precision Tolerance: Housing bore accuracy ≤ IT6 grade (ISO 286)
• Custom Combinations: Match any housing material/coating with bearing type (e.g., nickel-plated steel housing + stainless steel angular bearing)
• Lifecycle Advantage: 2x operational lifespan through optimized heat treatment (hardness: 58–62 HRC)
• **Global and DIN standards certification

Industry Applications

• Food & Pharma: Stainless steel + nickel-plated units meeting FDA/EC1935 requirements
• High-Temperature: Anodized aluminum housings (–50°C to +250°C operational range)
• Corrosive Environments: Burnished stainless steel assemblies for offshore/wastewater plants
• High-Speed: Dynamic-balanced angular bearings (up to 30,000 rpm)
