دی Tapered Roller Bearing 31322 is a specific type of rolling-element bearing designed to handle combined radial and axial (thrust) loads. Here are the key details about this bearing:
31322 Tapered Roller Bearing Specifications
ISO Designation: 31322
Metric Dimensions (ملی میٹر):
Bore Diameter (d): 110 ملی میٹر
Outer Diameter (D): 240 ملی میٹر
چوڑائی (T or B): 50 ملی میٹر (depends on the manufacturer’s exact design)
Dynamic Load Rating (C): ~300 kN (varies by manufacturer)
Static Load Rating (C₀): ~400 kN (varies by manufacturer)
Speed Rating: Depends on lubrication and mounting conditions.
Features & Applications
Load Capacity: Handles high radial and axial loads in one direction (usually requires a matched pair for bidirectional axial load support).
Common Uses:
Heavy machinery (gearboxes, mining equipment)
Automotive wheel hubs (especially in trucks)
Industrial gear drives
Construction equipment
Mounting Notes
Tapered roller bearings are typically mounted in pairs (back-to-back or face-to-face) to manage axial loads in both directions.
Requires proper preload adjustment for optimal performance.
Interchangeable Part Numbers
Different manufacturers may use slightly different codes:
