Cases

Background  

A Sichuan-based machine tool manufacturer previously relied on INA YRT series rotary table bearings (YRT260, YRT325, YRT395) for their horizontal machining centers. However, the high cost and long lead times of imported bearings prompted them to seek a domestic alternative.  

Challenges  

Initial hesitation due to concerns about quality and precision compared to INA bearings.  

Need for P2-level accuracy (≤0.005mm runout) for high-speed CNC machining.  

Long-term reliability under heavy cutting loads.  

Presented successful applications in European CNC equipment and domestic high-end machine tools.  

Provided sample bearings (YRT260, YRT325, YRT395) for testing.  

Test Results:  

Runout accuracy: ≤0.005mm (P2 grade, matching INA standards).  

Rigidity: Equivalent to INA under dynamic loads.  

Service life: 20,000+ hours in continuous operation.  

30% lower cost than INA bearings.  

4-week lead time (vs. 12+ weeks for imported bearings).  

Outcome  

Metric Improvement  

Bearing Cost 30% reduction vs. INA  

Lead Time 4 weeks (vs. 12+ weeks)  

Accuracy Maintained P2 grade (≤0.005mm runout)  

Adoption Full replacement of INA bearings (YRT260, YRT325, YRT395, YRT580)  

Client Feedback:  

'Newbee Transmission's YRT bearings perform identically to INA's at a fraction of the cost and faster delivery. We've fully switched to their products for our machining centers.'
