Stop Gearbox Failures with Heavy Duty Double Row Angular Contact Ball Bearing 3306-A-2Z TN9-MT33

Manufacturing downtime from bearing failures costs producers thousands daily. Gearbox and reducer breakdowns often stem from substandard bearings that can’t handle radial and axial loads, leading to premature wear and production halts. Many suppliers enforce high minimum order quantities, leaving maintenance teams waiting weeks for critical replacements. Even worse, inconsistent quality across multiple vendors complicates inventory management and reliability.

Precision-Engineered Bearings for Uninterrupted Gearbox Performance

Our Heavy Duty Double Row Angular Contact Ball Bearing 3306-A-2Z TN9-MT33 addresses these challenges with robust design and flexible supply. Engineered for gearboxes and reducers, this bearing combines P0-P6 precision ratings and multiple cage material options (steel, copper, nylon) to match diverse operating conditions. With a 1-piece minimum order quantity for standard bearings and 3-5 day sample delivery, we eliminate long lead times, ensuring your maintenance teams get the parts they need when urgency strikes.

Built to Withstand Heavy Loads in Critical Machinery

This double row angular contact bearing excels in high-torque applications like industrial gearboxes and reducers, where simultaneous radial and axial loads are common. Its separated structure allows for easy mounting and dismounting, simplifying maintenance. The bearing’s design accommodates misalignment while maintaining stability, making it ideal for heavy-duty equipment in automotive manufacturing, agricultural machinery, and construction—environments where reliability directly impacts operational efficiency.

Technical Features That Ensure Long-Term Performance

Key technical attributes set this bearing apart for demanding applications. The precision rating (P0-P6) controls dimensional accuracy, reducing vibration and noise in high-speed gearboxes. Multiple cage materials offer tailored solutions: steel cages for high-temperature resilience, copper for enhanced heat dissipation, and nylon for reduced friction in moderate-load scenarios. Lubricated with high-performance oil grease, the bearing maintains optimal operation across a range of speeds, while its bearing steel construction ensures durability against wear and fatigue, extending service life in continuous-duty equipment.

Why Genuine Bearings Lower Total Cost of Ownership

Choosing authentic double row angular contact bearings avoids the hidden costs of counterfeits. Inferior bearings often fail within months, causing unplanned downtime, repair labor expenses, and potential damage to adjacent gearbox components. Our products meet ISO international standards, backed by strict quality control—including incoming raw material inspections and full-process production supervision. While counterfeits may offer lower upfront prices, the 12-month warranty on our bearings ensures protection against manufacturing defects, delivering better long-term value through reduced replacement frequency and enhanced equipment uptime.
