Background
A leading Serbian optical research institute specializing in photonics, applied optics, and precision instrumentation selected Newbee Transmission's ZKLDF series bearings for their high-precision theodolite systems after rigorous testing. The bearings met critical ±3 arc-second angular accuracy requirements for both azimuth and elevation axes.
Key Challenges
Extreme precision demanded for optical alignment systems (±3 arc-seconds)
Smooth rotational performance with near-zero backlash
Long-term stability in variable environmental conditions
Technical Solution
ZKLDF Series Precision Bearings
Accuracy: ±3 arc-second angular deviation (verified via laser interferometry)
Design Features:
Special-grade steel races with ultra-precise grinding
Custom preload adjustment for near-zero axial play
Low-torque lubrication for smooth motion
Environmental Resistance:
Stable performance across -30°C to +80°C
Corrosion-resistant seals for laboratory/field use
Verification Process
Test Parameter Requirement Newbee Transmission Result
Angular accuracy ≤±3 arc-sec ±2.8 arc-sec |
Rotational torque ≤0.05 N·m 0.04 N·m |
Axial/radial runout ≤1.5 μm 1.2 μm |
Service life 50,000 cycles No degradation after 60,000 test cycles
Client Benefits
60% cost reduction compared to German/Swiss alternatives
8-week lead time (vs. 20+ weeks for competitors)
Local technical support for installation/calibration
Feedback:
'After testing multiple suppliers, Newbee Transmission's bearings delivered unmatched precision at reasonable cost. We've standardized on their ZKLDF series for all our optical instruments.'
