CAT 212-5027 is a Caterpillar single-row tapered roller bearing with a cone-only inner ring. It must be used with a corresponding outer ring (cup) and is suitable for heavy-duty equipment transmission systems. The following are its core specifications:
Core Parameters:
Item Details
Inner Diameter: 9.25 inches (234.95 mm)
Width: 4.4375 inches (112.71 mm)
Material: Alloy steel, specially heat-treated for excellent strength and wear resistance.
Structure: Inner ring assembly including rollers and cage; inner and outer rings are separable, suitable for high-precision assembly and clearance adjustment.
Application Scenarios: Suitable for axles, differentials, final drives, or gearboxes in off-road heavy-duty equipment such as Cat 793 series mining trucks. It withstands combined radial and unidirectional axial loads and is suitable for high-load, impact-prone conditions.
Used in power transmission systems to ensure coordinated operation of transmission components, reduce friction and wear, and extend equipment life.
Performance Characteristics: The convex design of the rolling elements and special surface polishing reduce friction and wear, extending wear life to twice the industry standard under harsh operating conditions.
Shard-resistant materials and a dedicated sealing design make it suitable for dusty, heavy-duty engineering environments, improving reliability and durability.
The detachable structure facilitates installation, maintenance, and clearance adjustment, meeting the high-precision assembly requirements of CAT equipment.
