Process & Testing Capabiliites

CCTY Bearing controls all major critical processes involved in manufacturing a high-quality bearings. For example, unique process controls include requiring raw material suppliers to provide quality certificates with every lot. CCTY Bearing is committed to handling process control at a high level, a commitment we’ve made to ensure the trust and safety of our customers.

Raw Material

CCTY views its steel vendors as partners and as a result is very selective. Through strict controls, spot and system audits and quality reviews, CCTY will only work and sign agreements with the best suppliers.

CCTY requires all raw material suppliers to provide quality certificates with each lot. All lots are checked and validated by our quality control department. These procedures guarantee that all materials comply with CCTY’s strict quality controls. The end result is a quality product that will meet the customer’s specifications.

Heat Treatment

Heat treatment is a critical process for bearing manufacturers.  CCTY’s furnaces are state of the art and contain automatic monitoring and alarm systems, are computer controlled with automatic data collection and use SPC chart analysis. All of these measures helps guarantee a controlled and stable heat treatment process.

CCTY has the capability to provide customers with through hardening, case hardening and induction hardening.

Grinding

Grinding is an important process since this influences the precision and the life of a bearing. CCTY mainly uses CNC grinding machines, which guarantee stable production. CCTY also uses a modern centralized cycling station for the cooling liquid used on our production lines.  CCTY establishes detailed control plans and follows strict SPC procedures to monitor and measure production on an on-going basis.

Surface treatment

Similar to heat treatment, surface treatment is another special process during the manufacturing. CCTY uses automatic surface treatment production lines, to strictly control all process parameters (such as temperature and PH value), computer online control and data collection, and SPC chart analysis, which provides good, stable process control.

CCTY’s main surface treatment techniques are phosphate and black oxide.

Based on customer requirements, CCTY also can provide other surface treatments such as chrome plating, zinc plating, zinc cobalt plating, and more. All treatments comply with environmental standards and salt spray requirements.

Assembling Process

For our products with high precision (for example, deep groove ball bearings), CCTY uses a dust free assembly room to guarantee a clean environment. CCTY also uses automated assembling equipment for matching balls and rings, maintaining proper grease fill and sealing/shielding operations.

Testing

CCTY has many different types of test equipment on site.

Some, but not all of our test equipment includes:

Life Testing

For all core products, CCTY designs specific life testing machines that simulate customer applications. CCTY is also able to perform a comparison analysis with our main competitors to establish various quality benchmarks.

Tensile Strength Test

Verify the mechanical characteristics of tensile and yield strength.

Salt-Spray Test

Verify rust requirements of our surface treatments.

High and Low Temperature Test

Verify the high and low temperature requirements of our materials or finish.

Dust-Proof and Sealing Performance Test

Verify the dust proof and sealing requirements of our products.

Test Equipment

CCTY only uses state of the art measuring equipment such as Taylor Hobson, Talyrond and profile analysis machines.
