Prevent Equipment Downtime with High Precision Double Row Angular Contact Ball Bearing 3217-a
Equipment operators know the frustration of unexpected shutdowns caused by bearing failures. When precision matters—whether in automotive transmissions or machine tool spindles—using substandard bearings can lead to costly production delays and increased maintenance. Many suppliers force large minimum orders or long lead times, leaving you waiting for critical components when you need them most.
High Precision Angular Contact Ball Bearings for Demanding Applications
Our Double Row Angular Contact Ball Bearing 3217-a is engineered to solve these challenges. With P4 precision grade and Gcr15 steel construction, it delivers the stability and durability required for high-performance automotive and machine tool applications. Backed by decades of manufacturing experience, we offer flexible order policies—including 1 piece MOQ for standard bearings—and efficient delivery, with sample orders shipped in 3-5 working days.
Optimal Performance in Critical Operating Conditions
This Double Row Angular Contact Ball Bearing excels in applications requiring simultaneous radial and axial load handling. Its angular contact design ensures precise alignment, making it ideal for high-speed rotations in machine tool spindles and automotive transmission systems. Whether operating under heavy loads or continuous duty cycles, the bearing maintains consistent performance, reducing the risk of unplanned downtime.
Technical Features That Ensure Reliability
The 3217-a Bearing’s P4 precision rating guarantees minimal runout and vibration, critical for maintaining machining accuracy in CNC equipment. Constructed from high-grade Gcr15 bearing steel, it offers excellent wear resistance and fatigue strength, extending service life even in demanding environments. Available with steel, copper, or nylon cages, the bearing can be tailored to specific application needs—steel cages for high-temperature resistance, nylon cages for reduced noise, and copper cages for heavy-load capacity. Lubricated with premium oil grease, it ensures smooth operation across a wide range of speeds.
Choose Quality to Avoid Hidden Costs
Opting for low-quality bearings may seem cost-effective initially, but the hidden expenses add up. Early failure can cause secondary damage to expensive equipment, while frequent replacements disrupt production schedules. Our bearings meet ISO international standards and undergo strict quality control—from raw material inspection to full-process production supervision. This commitment to quality reduces total cost of ownership by minimizing downtime, maintenance, and replacement frequency.
