Deep groove ball bearings stand as the pinnacle of versatility and reliability in ball bearing technology, making them the top choice across diverse applications.
We meticulously manufacture bearings across various precision levels, ensuring unparalleled performance.
Our precision hierarchy is defined as follows: P0 < P6 < P5 < P4 classes of ball bearings.
Precision classes are specified as P0 (ABCE-1) = +0-0.007MM; P6 (ABCE-3) = +0-0.006MM; P5 (ABCE-5) = +0-0.0005MM; P4 (ABEC-7) = +0-0.004MM.
Level P0 bearings serve most general applications, while P5 and P6 levels cater to high-precision needs, including aerospace and aviation sectors.
In terms of noise performance, we craft bearings across a range of noise levels to meet your specific needs.
Our noise classifications include: Z1, Z2, Z3, and Z4. noise level.
Noise specifications are as follows: Z1 at 33-38 decibels; Z2 at 28-32 decibels; Z3 at 22-25 decibels; Z4 at a whisper-quiet 15-21 decibels.
