Roller Bearings Certifications And Quality

The company has been ISO 9001 certified for several years. This has allowed it to constantly update and monitor all company processes to ensure they comply with standards. Aspects considered include: planning of quality system management activities through inspections, preventive and corrective actions, design control, grading and monitoring of suppliers’ performance (in terms of quality and service), monitoring of customer satisfaction and immediately dealing with complaints, control of measuring instruments, incoming and outgoing quality controls and monitoring of all company processes.

Audits conducted on our manufacturing partners are a very important tool for ensuring consistent quality over time.
We have structured specific partner- and product-based audit templates.
We perform six-monthly audits on our manufacturing partners and Lyra Bearing has qualified staff and an office in Jinan (China) to ensure a constant presence.

Constant cooperation with its manufacturing partners is one of Lyra Bearing’s core values. Sharing control plans, inspection procedures and other relevant material lays the basis for guaranteeing a top-quality finished product.
Our technical department exchanges know-how with our manufacturing partners and any problems encountered are discussed and resolved jointly. These activities are designed to ensure the goal of quality is not an end in itself but a means of continuous improvement.

Quality procedures or manuals are not enough to ensure that the products supplied meet the same quality standards as an original equipment component.
Testing delicate components such as bearings is a dedicated activity. Sometimes we are able to do this in-house, in other cases we outsource the testing or carry it out directly on the machines or systems, by mutual agreement with the customer. The main tests performed are as follows:

• Dynamic or endurance tests: these are carried out on bearings to establish product durability under difficult conditions in order to ensure their reliability during normal use.
• Static or stress tests: these assess the way materials respond to endogenous and exogenous causes in order to ensure a long product lifetime.
• Tests on materials, hardness tests, micrographic analyses and other tests ensure raw material continuity and quality.

The sizes and appearance of all incoming components are checked by staff in the Quality department using a continually updated control system that has been tried and tested over time. Sample checks are also carried out on outgoing goods using a level II AQL system to ensure products are complete and compliant before they reach our customers.

We are also able to provide other tests through close partnership with qualified, certified laboratories. Here are some of them:

• Visual and micrographic examinations: images are analysed using a optical microscope. The metallographic structure of the sample is examined to identify any defects.
• Fractographic examinations using optical microscopy (stereoscope) and electron microscopy (SEM) techniques.
• Microhardness test: a hardness test is performed according to the Vickers scale.
• Dimensional measurements: analysis of dimensions.
• EDS microanalysis: this analysis identifies any defects in the metal. Chemical analysis: analyses the percentage of metallic elements in the sample.
