| C/3 | Radial Internal Clearance Group C3 | Provides greater than normal clearance for thermal expansion in high-speed applications |
1319-K C/3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact configuration creates a robust bearing structure capable of handling significant radial loads (29,925 lbf dynamic rating) while maintaining dimensional stability under heavy operating conditions.
Precision Engineering: With tight dimensional tolerances (bore: -0.02mm to 0, OD: -0.03mm to 0) and CN clearance group, this bearing ensures precise rotational accuracy and consistent performance in precision machinery.
Optimized Material Selection: Chrome steel rings and balls combined with a stainless steel cage provide excellent corrosion resistance and durability, while the cage design contributes to stable operation at the limiting speed of 4,300 rpm.
Mounting Advantages: The 1:12 tapered bore facilitates precise mounting and dismounting, allowing for accurate axial positioning and secure fit on matching tapered shafts.
