32319-A

Engineered for extreme rigidity, the 32319-A is a metric-sized single-row tapered roller bearing designed to manage heavy combined radial and thrust loads. With a 95mm bore and a 200mm OD, this unit utilizes an optimized internal geometry that significantly cuts down on frictional heat during high-speed rotation. Unlike non-separable bearing types, the 32319-A features a detachable cup (outer ring) and cone (inner ring/cage assembly), which allows for independent mounting and easier maintenance in tight housing configurations. It conforms to DIN ISO 355 standards, ensuring it meets international interchangeability requirements for industrial machinery.

Performance-wise, the 32319-A delivers a massive dynamic load rating of approximately 530 kN and a static capacity of 710 kN. The "A" suffix denotes an enhanced internal design, often involving improved raceway finishes that support better lubricant film formation under stress. These bearings are staple components in heavy-duty gearboxes, mining equipment, and large-scale vehicle axles where axial displacement must be kept to a minimum. Because the contact angle allows for high axial force absorption, these units are frequently installed in pairs (face-to-face or back-to-back) to provide precise shaft guidance in both directions.
