Applications
The 7014 series (7014C / 7014AC / B7014) high-precision angular contact bearings feature 70mm bore size, large load capacity and excellent high-speed thermal stability. They are widely applied in medium-large high-power CNC spindles, grinding spindles and industrial high-speed rotary spindles. Below are the fully compatible mainstream spindle models sorted by equipment category:
1. CNC Milling & Machining Center Spindles
BT40 / BT50 high-speed machining center spindles, vertical machining center (VMC) spindle units, horizontal machining center (HMC) built-in motor spindles, mold high-speed milling spindles, heavy-duty cutting CNC spindle assemblies. Suitable for 8000–12000rpm long-cycle high-load processing scenarios.
2. High-Precision Grinding Machine Spindles
Internal grinding machine high-frequency spindles, external cylindrical grinding spindles, tool grinding machine spindles, surface grinding machine precision rotary spindle units. The 7014 bearing's ultra-low runout performance ensures ultra-fine grinding surface finish and dimensional accuracy.
3. Drilling & Tapping Machine Spindles
High-speed drilling and tapping machine servo spindles, multi-axis drilling spindle units, automated production line dedicated high-speed rotary spindles. It adapts to frequent start-stop and continuous high-temperature operating conditions with stable anti-fatigue performance.
4. Industrial High-Frequency Built-In Motor Spindles
1.5kW–7.5kW high-power built-in motor spindles, water-cooled high-speed spindle units for metal processing, oil-air lubrication industrial spindle systems. Matches the 7014 series' high-temperature resistance and high-speed dynamic stability.
5. Special Precision Equipment Spindles
Precision rotary table main shafts, industrial robot joint high-load rotary units, high-power compressor rotary spindles, large automated precision finishing equipment spindles.
6. Matched Precision Bearing Configuration Features
7014 series bearings are commonly configured with DBL back-to-back pairing and DT tandem pairing for medium and high rigidity spindle systems. With upgraded high-temperature clearance and heat-resistant accessories, they solve thermal expansion jitter and precision attenuation problems of large-bore spindle bearings, serving as the core upgrade replacement for medium-large high-speed machine tool spindles.
