Green manufacturing and sustainable development in the bearing industry cover many aspects, and the following is a detailed introduction:

### Green manufacturing technology and process
- **Dry processing technology**: Use dry cutting and hard cutting processes to reduce or avoid the use of cutting fluids, grinding fluids and other environmentally polluting substances. For example, there is a process abroad that first hard turns and then rolls the bearing raceway surface, which can reduce the cost to 55% of the original and increase the life by five times.
- **Optimize production processes**: Improve production efficiency by improving processes and equipment, reduce energy consumption and waste generation. For example, SKF (Jinan) has developed a dual separation technology system and established a centralized liquid supply circulation system for cutting fluids, super-fine oils and cleaning fluids, reducing the amount of waste oil and waste liquids produced by about 1,000 tons each year, saving about 1.3 million yuan in costs.
- **Use environmentally friendly materials**: Give priority to renewable, recyclable and low-pollution materials, such as using plastic bearings in some application scenarios, especially degradable plastic bearings, and recycling steel, etc.

### Resource recovery and recycling
- **Recycling of waste bearings**: Establish a complete recycling system for waste bearings to recycle and reprocess bearings that have reached the end of their service life. Through remanufacturing technology, old bearings can be repaired or upgraded to restore them to their original or better performance state. Recycled bearings can reduce 70% of waste compared to producing new bearings.
- **Production waste recycling**: Classify and recycle waste generated during the production process, such as metal chips and scraps, to maximize the use of resources. At the same time, strengthen the recycling of packaging materials. SKF has reduced the consumption of packaging materials by about 80%-90% by optimizing bearing packaging materials.

### Energy management and energy-saving measures
- **Use of clean energy**: Use clean energy such as solar energy, wind energy, and geothermal energy to replace traditional fossil energy. For example, Xiangzhou Company invested in the construction of photovoltaic power generation projects, which can reduce carbon emissions by 13,600 tons per year; SKF built a distributed intelligent photovoltaic power generation system, reducing annual electricity costs by 25%, and introduced ground source heat pump technology to reduce cooling and heating energy consumption by 30%.
- **Energy-saving equipment and technology**: Use high-efficiency and energy-saving motors, inverters and other equipment to optimize energy supply and transmission systems and improve energy utilization efficiency. SKF plans to build a smart carbon monitoring and management system to achieve an annual energy consumption reduction of 5% through real-time monitoring and analysis.

### Sustainable corporate management and strategy
- **Establish a green management system**: Enterprises need to formulate a complete green manufacturing and sustainable development strategy, and integrate environmental protection concepts into all aspects of the company's decision-making, production, sales, etc. For example, establish an environmental management system to ensure that the company's production and operation activities comply with environmental laws, regulations, standards and requirements.
- **Strengthen employee training and education**: Improve employees' environmental awareness and skills, make them understand the importance and operating specifications of green manufacturing, and encourage employees to actively participate in environmental protection actions and put forward innovative environmental protection suggestions. SKF creates a green corporate culture by making promotional display boards, holding training lectures and other activities.
- **Carry out green supply chain management**: Promote green development with suppliers and partners, require suppliers to provide environmentally friendly materials and products, and strengthen environmental management of the entire supply chain.

### Policy support and industry cooperation
- **Policy guidance**: The government should issue relevant policies and regulations to encourage and support green manufacturing and sustainable development in the bearing industry, such as giving environmental protection enterprises tax incentives and financial subsidies, and formulating strict environmental protection standards and access systems.
- **Industry collaboration**: Bearing companies should strengthen cooperation and exchanges, jointly carry out the research and development and promotion of green manufacturing technology, and share experiences and best practice cases. At the same time, companies should also cooperate with universities and research institutions to accelerate technological innovation and talent training.
