The 6313/C3 SKF is a premium open-type deep groove ball bearing manufactured by SKF, designed with enlarged C3 radial internal clearance. It delivers outstanding high-speed running stability, strong shock resistance and excellent load bearing performance, widely adopted for medium and heavy load mechanical operation under high temperature and interference fitting conditions.
In strict accordance with ISO international bearing standards, its precise dimensions are as follows: inner diameter 65 mm, outer diameter 140 mm, overall width 33 mm, standard chamfer 2.0×45 mm, tolerance grade P6, radial clearance class C3. It owns stable dynamic load rating and static load rating, with accurate size tolerance to realize perfect matching with shaft and housing seat.
For material configuration, both inner ring and outer ring adopt high-purity 100Cr6 bearing steel, overall quenched hardness reaches HRC 61-63, featuring superb wear resistance, fatigue resistance and oxidation resistance. Precision steel balls are made of the same high-grade bearing steel with super finished surface. The pressed steel cage ensures stable guidance of rolling elements, low noise operation and strong structural durability under continuous running.
Its mature production processes include hot forging forming, high-precision CNC turning, isothermal quenching tempering, raceway precision grinding and ultra-finishing treatment. The optimized heat treatment effectively eliminates internal stress, while ultra-finishing greatly reduces surface friction coefficient, laying solid foundation for high efficiency and long service life.
Calculated in accordance with ISO 281 bearing life standard, the standard L10 service life of 6313/C3 SKF reaches 62000 hours under rated load, normal speed and qualified lubrication environment. Its actual service life is mainly affected by operating load, rotating speed, ambient temperature, lubrication state and installation concentricity.
This C3 clearance SKF bearing is mainly applied in automotive drive systems, industrial machine tools, fans and blowers, water pumps, mining machinery and general industrial transmission equipment. The extra clearance design can effectively compensate thermal expansion, avoid bearing jamming and adapt to high-temperature continuous working scenes perfectly.
In daily maintenance, regular lubrication maintenance is required every 300 working hours; high-temperature anti-pressure lithium grease is recommended for filling. Keep the bearing surface clean away from dust and moisture. Regularly check running sound, rotating flexibility and working temperature, and replace components timely once abnormal vibration or abrasion occurs.
During installation, thoroughly clean matching parts in advance, adopt standard press fitting method and forbid violent knocking. Strictly control shaft alignment error, implement standard fastening torque, and conduct no-load trial operation after installation to confirm smooth rotation without abnormal noise, so as to guarantee long-term stable operation of 6313/C3 SKF bearing.
