Case Study: Angular Contact Ball Bearings for CNC Machinery

Customer Background

A customer from Europe contacted us while looking for angular contact ball bearings for CNC machining equipment.

The customer's existing supplier had difficulty maintaining stable delivery times, so they wanted to find a new bearing manufacturer in China that could provide reliable quality and long-term supply.

Customer Requirements

The customer needed bearings with:

• High rotational accuracy

• Good high-speed performance

• Low vibration

• Stable dimensional accuracy

• Reliable performance during continuous operation

• Competitive pricing

• Consistent quality for repeat orders

The customer initially provided the bearing model and application information and asked us to confirm whether the bearing was suitable for their equipment.

Our Solution

Based on the customer's requirements, we supplied 7205B Angular Contact Ball Bearings.

The 7205B is a single-row angular contact ball bearing designed to accommodate both radial and axial loads. Its angular contact design makes it suitable for machinery requiring accurate shaft positioning and stable rotation.

The bearing is manufactured from GCr15 chrome bearing steel and can be supplied in different precision grades according to the customer's requirements.

For CNC machinery, we paid particular attention to:

• Dimensional accuracy

• Raceway quality

• Rotational smoothness

• Bearing clearance

• Noise and vibration

• Surface quality

We also provided product photos and detailed specifications before production so that the customer could confirm the model and configuration.

Quality Inspection

To ensure consistent quality, the bearings were inspected before shipment.

The inspection focused on key parameters such as:

Dimensional Inspection
The inner diameter, outer diameter and width were checked against the required specifications.

Rotation Inspection
The bearings were checked for smooth rotation and abnormal noise.

Appearance Inspection
The bearing surfaces, packaging and overall appearance were carefully inspected.

Packaging Inspection
Each bearing was properly packaged to reduce the risk of damage, contamination or moisture during international transportation.

Result

The customer successfully tested the bearings in their CNC equipment and confirmed that the products met their performance requirements.

After the initial order, the customer began discussing additional bearing models with us for other machines.

The cooperation developed from a single trial order into a potential long-term supply relationship.
