• Ring Material: High precision steel to ensure strength and reduce wear.
• Cage: Reinforced nylon or steel, depending on the specific design, to ensure good ball distribution and reduce friction.
• Seal Type: Non-seal, 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): 10 mm
• 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 can be "C0" for minimum radial clearance.
