Angular Contact Ball Bearings

1. High Precision Positioning : The 7308B miniature angular contact ball bearing is manufactured with very high precision. The inner and outer rings and rolling elements are precisely machined and subjected to strict quality control, ensuring a tight fit and minimal clearance during use. This high-precision manufacturing process effectively reduces mechanical errors, allowing for micron-level or even smaller adjustments when focusing the microscope.

2. Excellent Rigidity and Stabilityce : The contact angle of the small balls in the 7308B miniature angular contact ball bearing is inclined toward the axial direction, allowing it to effectively withstand both axial and radial loads, providing higher rigidity. It distributes loads better under stress, reducing deformation and maintaining a stable operating state.

3. Low Friction : The 7308B miniature angular contact ball bearing is made from high-strength, low-friction coefficient materials, featuring excellent surface smoothness and wear resistance, which helps reduce friction and wear. The geometric shape, dimensional tolerances, and surface roughness of the inner and outer rings are strictly controlled. The high-precision fit minimizes clearance during operation, further reducing friction.

Additional Notes:

After thorough market research and technical evaluation, the customer in Brazil decided to purchase QIBR's 7308B miniature angular contact ball bearings to meet the stringent requirements for precision and stability in their microscope focusing mechanisms. The materials used by QIBR are carefully selected, often incorporating high-performance materials to enhance wear resistance and improve reliability under high loads and speeds. Using high-precision computer-aided design software ensures that each bearing achieves extremely high manufacturing precision, allowing QIBR's miniature bearings to deliver excellent stability and response speed in microscope focusing mechanisms.
