• Ring Material: High precision steel to ensure resistance and reduce wear.
• Cage: Reinforced nylon or steel, depending on the specific design, to ensure good ball distribution and reduce friction.
• Seal Type: Sealless, but designed to operate in controlled environments or with external lubricant.

3. Measurements and Technical Specifications

• Hole diameter (d): 35 mm
• External Diameter (D): 55 mm
• Width (B): 10mm
• Number of Crowns: 1
• Hole Type: Cylindrical

4. Performance and Mechanical Characteristics

• Dynamic Load Coefficient (C): 16.6 kN
• Basic Static Load Coefficient (C0): 8.7 kN
• Limit speed: 12,000 r/min (depending on lubrication and mounting conditions)
• Internal Radial Clearance: Normally specified per customer request, but may be "C0" for minimum radial clearance.
• Dimension Tolerance Class: P4 (High precision)
• Rotation Error Tolerance Class: P4 (High precision)

5. Additional Features

• Contact Angle: 25°, which allows the bearing to withstand high axial loads in addition to radial loads.
• Lubrication: Can be lubricated with grease or oil. The sealless version requires adequate lubrication to maintain optimal performance.
• Accuracy: Class P4, indicating very tight tolerance, ensuring low vibration and noise.

6. Mathematical Formulas for Characteristics

• Dynamic Load (C): Determines the maximum load a bearing can withstand for a specific duration.
