Reduce Downtime with SKF 3306 A-2Z Tn9/C3 Double Row Angular Contact Ball Bearing

Construction machinery operators know the cost of unexpected downtime—every hour a loader or excavator sits idle eats into project deadlines and profits. Sourcing reliable bearings often means coordinating with multiple suppliers, facing inconsistent quality, and waiting weeks for critical parts. When bearings fail prematurely due to substandard materials or imprecise manufacturing, the result is costly repairs and missed milestones.

Genuine SKF Bearings, Stocked and Ready for Immediate Shipment

As an official SKF distributor, we eliminate these frustrations with our ready stock of Double Row Angular Contact Ball Bearing 3306 A-2Z Tn9/C3. Designed specifically for the heavy loads and shock resistance required in construction machinery, this bearing combines SKF’s engineering expertise with our streamlined procurement process. Instead of managing multiple vendors, you get a single point of contact for authentic, precision-tested bearings that meet ISO 9001 and DIN standards.

Engineered for Construction Machinery’s Toughest Conditions

This Angular Contact Ball Bearing 3306 excels in applications where radial and axial loads act simultaneously, such as in the pivot points of excavator arms and loader buckets. Its double row design provides higher load capacity than single row bearings, while the 2Z steel shields protect against dust, debris, and moisture common in construction sites. The Tn9 polyamide cage ensures stable operation even under variable speeds, making it ideal for equipment that alternates between heavy lifting and rapid movement.

Technical Features That Maximize Equipment Reliability

The C3 clearance rating of this SKF 3306 A-2Z Tn9/C3 Bearing accommodates thermal expansion during prolonged operation, reducing internal stress and extending service life. Its precision rating options (including P2/P4 grades) ensure minimal vibration and noise, critical for maintaining operator comfort and preventing premature wear on connected components. The bearing steel construction offers excellent fatigue resistance, while the oil and grease lubrication compatibility allows adaptation to different maintenance schedules and operating temperatures.

Avoid the Hidden Costs of Non-Genuine Bearings

Choosing unauthorized bearings may seem cost-effective initially, but the long-term risks are substantial. Counterfeit products often lack proper material heat treatment, leading to early spalling or cage failure. A single bearing failure in a construction machine can cause secondary damage to gears, shafts, and hydraulic systems, resulting in repair costs 10–15 times the price of a genuine bearing. Our ISO 9001-compliant inspection process ensures every bearing meets SKF’s strict quality standards, protecting your equipment investment and reducing total cost of ownership.
