What's the Performance Features of 71901 CE/HCP4ADGA Bearing?
The 71901 CE/HCP4ADGA angular contact ball bearing is engineered
for high-precision and high-performance applications, featuring
very tight tolerances suitable for precise machinery, the ability
to handle both radial and axial loads simultaneously, high-speed
operation with stability, low torque and friction for energy
efficiency, enhanced rigidity for accuracy under heavy loads,
durability with extended service life, effective performance across
a wide temperature range.
What's the Applications of the 71901 CE/HCP4ADGA Bearing?
The 71901 ACE/HCP4ADGA bearing, a super precision angular contact ball bearing,excels in
high-speed operations with low friction heat generation, making it
ideal for various axes in high-speed machining centers (both
horizontal and vertical) and milling machines within metal cutting
applications. It effectively reduces energy loss and extends
machine tool life. As an E-type design bearing, it features a
smaller contact angle and more balls, suitable for very high speeds
but with potentially lower load-carrying capacity compared to
D-type designs. This bearing also maintains stability at high
rotational speeds in internal grinders, reducing wear and improving
machining accuracy. Additionally, its characteristics make it
suitable for high-speed operation under light load and
low-temperature conditions in certain woodworking machine tools.
