Eliminate Downtime with Precision 3313 Double Row Angular Contact Ball Bearings
Equipment failures from substandard bearings cost manufacturers thousands in lost production daily. When your automotive machinery needs reliable radial load support with precise rotation, waiting weeks for custom orders or risking counterfeit parts isn’t an option. The 3313 double row angular contact ball bearing solves these challenges with proven performance in high-stress applications.
Engineered for Automotive Machinery’s Toughest Demands
Our Double Row Angular Contact Ball Bearing 3313 delivers the stability automotive manufacturers require. With P0-P4 precision grades, it maintains tight tolerances under variable loads—critical for transmission systems and steering mechanisms. Unlike generic bearings, our 3313 model combines separated design with multiple cage material options to adapt to your specific operating conditions, from standard passenger vehicles to heavy-duty commercial fleets.
Optimal Performance in Critical Operating Environments
This angular contact ball bearing excels in applications requiring simultaneous radial and axial load handling. Its double row configuration provides higher rigidity than single row alternatives, making it ideal for high-speed rotating components in automotive machinery. Whether operating in temperatures from -30°C to 120°C or under continuous vibration, the 3313 bearing maintains consistent performance thanks to premium bearing steel construction and precision manufacturing.
Technical Specifications That Matter in Real-World Applications
The 3313 bearing’s precision rating directly impacts your machinery’s efficiency. P0 grade suits general industrial use, while P4 grade delivers the tight runout control needed for precision gearboxes. The choice of cage material—steel for high load capacity, nylon for reduced noise, or copper for elevated temperatures—allows customization to your exact application. Radial load capability ensures reliable power transmission, while the separated design simplifies installation and maintenance, reducing assembly time and costs.
Why Precision Bearings Lower Total Operating Costs
Choosing genuine high-precision bearings eliminates hidden expenses associated with inferior alternatives. A 3313 bearing with P4 precision reduces vibration by up to 30% compared to lower grades, extending gear and shaft life. Properly lubricated with high-quality grease, it maintains optimal friction levels, lowering energy consumption. Our ISO 9001:2015 certified production ensures consistent quality, meaning fewer replacements and less unplanned downtime—critical factors in automotive manufacturing’s tight production schedules.
