Factory wholesale Metal Measuring – Precision Granite Air Bearing – ZHONGHUI

It was not need to be check and replace lubrication because parts are needed less to support drive axis and oil is note needed.

And a film can be produced between air bearing and drive axis when the granite air bearing runs, and it can air bearing and drive axis from being worn, and dust and particles cannot enter between air bearing and drive axis by air of the bearing.

1. The granite is after a long-term natural aging, the organizational structure is uniform, the expansion cofficient is small, the internal stress completely disappeared.

2. Not afraid of acid and alkali corrosion, will not rust; do not need oiling, easy to maintain, long service life.

3. Not limited by the constant temperature conditions, and can maintain the high precision at room temperature.

4. No be magnetized, and can move smoothly while measuring, no tight feeling, free of the affect of moisture, good flatness.

We use various techniques during this process:

●  Optical measurements with autocollimators

●  Laser interferometers and laser trackers

●  Electronic inclination levels (precision spirit levels)

1. Documents together with products: Inspection reports + Calibration reports(measuring devices) + Quality Certificate + Invoice + Packing List + Contract + Bill of Lading(or AWB).

2. Special Export Plywood Case: Export fumigation-free wooden box.

3. Delivery:

1. We will offer technical supports for assembly, adjustment, maintain.

2. Offering the manufacturing &inspection videos from selecting material to delivery, and customers can control and know every detail at anytime anywhere.
