The 7306 Angular Contact Ball Bearing is a high-performance precision bearing designed to support combined radial and axial loads, with enhanced axial load capacity compared to standard deep groove ball bearings. Its optimized contact angle allows stable performance under high-speed and high-accuracy operating conditions.
Manufactured from premium chrome steel, and available in stainless steel and ceramic variants, the 7306 bearing offers excellent rigidity, low friction, and long service life. It is widely used in paired or duplex configurations to support bidirectional axial loads in demanding mechanical systems.
Due to its large size and strong load-carrying capability, the 7306 angular contact bearing is ideal for heavy-duty spindles, industrial machinery, and precision equipment requiring high stability and durability.

FAQ
Q1: What makes 7306 different from 7305 or 7206 bearings?
A: The 7306 has a larger size and higher load capacity, making it more suitable for heavy-duty applications compared to smaller series bearings.
Q2: Can 7306 bearings handle axial loads in both directions?
A: A single bearing supports axial load in one direction; for bidirectional loads, paired mounting is required.
Q3: Do you offer ceramic or high-precision versions?
A: Yes, we provide stainless steel, ceramic hybrid, and high-precision grades (P5/P4) for demanding applications.
