• 1.Structural Features: Both inner and outer rings feature tapered raceways, with truncated cone-shaped rolling elements. The inner ring, outer ring, rolling elements, and cage collectively form a complete, separable assembly.
• 2.Load-bearing capacity: Capable of simultaneously withstanding radial loads and unidirectional axial loads. Axial load capacity increases with contact angle; a larger contact angle makes it suitable for applications where axial loads constitute a higher proportion.
• 3.Applicable Conditions: Commonly used in machinery subjected to combined loads, such as automotive hubs, axles, and gearboxes, as well as machine tool spindles and mining equipment. Particularly suitable for low-to-medium speed applications involving impact or vibration.
• 4.Installation Requirements: Adjust the clearance during installation (achieved through relative axial displacement between the inner and outer rings). Excessive clearance may cause vibration and noise, while insufficient clearance may accelerate wear due to increased heat generation. A suitable locking device must be used in conjunction.
• 5.Performance Limitations: Cannot withstand bidirectional axial loads. For bidirectional load-bearing requirements, must be installed in pairs with opposing directions.
