Equipment failures due to substandard bearings cost manufacturers thousands in lost production each year. Many face challenges with bearings that fail prematurely under heavy loads, or struggle to source precise 35x80x21mm dimensions with consistent quality. When replacement parts have long lead times or unclear specifications, maintenance teams are forced into costly workarounds.
Our 6307 Deep Groove Ball Bearing addresses these issues with precision manufacturing and flexible supply options. Available in P0-P4 precision grades and Z1V1-Z3V3 vibration levels, this bearing delivers reliable performance in industrial machinery where radial load capacity and rotational accuracy are critical. With 1 piece MOQ for standard bearings and sample orders shipped within 3-5 working days, we support both emergency repairs and planned production needs.
This 35x80x21mm ball bearing excels in applications requiring high radial load handling and moderate speeds, such as electric motor spindles, conveyor systems, and gearbox assemblies. The single-row design and unseparated construction ensure easy installation and consistent operation, while options for Zz, 2RS, or open seals accommodate different contamination and lubrication requirements. Whether operating in dusty factory environments or clean production lines, the bearing steel material provides durability for extended service life.
Precision rating directly impacts operational stability—P4 grade bearings reduce vibration in high-speed applications like CNC machine tool spindles, while P0 grade offers cost-effective reliability for general industrial use. Vibration levels (Z1V1 to Z3V3) control noise output, a key consideration for indoor machinery where operator comfort is important. The radial load design makes this bearing ideal for equipment with primarily radial force, such as belt-driven conveyors, while the choice between grease or oil lubrication allows adaptation to operating temperature ranges and maintenance intervals.
Choosing genuine, high-precision bearings eliminates hidden costs associated with counterfeit products. Inferior bearings often fail within months, causing unplanned downtime, costly repairs to adjacent components, and lost production revenue. Our bearings meet ISO international standards and undergo strict incoming material inspection and full-process production supervision, ensuring consistent performance. With a 12-month warranty and free replacement for qualified defective products, we stand behind the reliability that lowers long-term operational expenses.
