Diverse Product Matrix

Shanghai Yisiou Trading Co., Ltd. offers customers a wide range of bearing product options to meet the needs of different industries and application scenarios.

Ceramic Bearings: Made of advanced ceramic materials, they exhibit unique performance advantages under specific working conditions, providing reliable solutions for customers in special environments.

Hybrid Ceramic Ball Bearings: As one of the company's core sales products, they skillfully combine the advantages of ceramic balls and metal components (such as bearing steel or stainless steel). Ceramic balls endow bearings with excellent performance:

High Temperature Resistance: Ceramic balls have a low thermal expansion coefficient, with a service temperature easily reaching above 220°C, far exceeding the approximately 160°C of ordinary bearings, and showing significant advantages in high-temperature environments.

High Rotational Speed: Ceramic balls possess oil-free self-lubricating properties with an extremely low friction coefficient. The rotational speed of bearings can usually reach more than 1.5 times that of ordinary bearings, perfectly meeting the requirements of high-speed rotating equipment.

Long Service Life: Their service life is 2-3 times that of ordinary bearings. Even in harsh conditions where grease dries up, they can still operate stably continuously, effectively reducing equipment maintenance costs and downtime.

Insulation Performance: Ceramic balls are excellent insulators, which can effectively achieve insulation between the inner and outer rings of bearings, ensuring the safe operation of equipment in conductive environments.

Lightweight: Ceramic materials are 60% lighter than steel, helping to reduce the overall structural weight, which is of great significance in fields with strict weight requirements.

Low Friction: Significantly reduce friction and operating temperature, decrease energy consumption, and provide strong support for enterprises to save energy and reduce consumption.

Electrically Insulated Bearings: With unique electrical insulation performance, they can effectively prevent current from passing through bearings, avoiding problems such as electric erosion caused by current. Widely used in occasions with high requirements for electrical insulation, ensuring the reliable operation of equipment.

Solid Oil Bearings: Adopting special solid lubrication technology, they do not require additional lubricating oil or grease, reducing lubrication maintenance work while avoiding environmental pollution caused by lubricant leakage. Suitable for scenarios with high cleanliness requirements or difficult lubrication maintenance.

Tapered Roller Bearings: Capable of withstanding large radial loads and combined axial loads, with high load-carrying capacity and rigidity. Suitable for mechanical equipment bearing heavy loads, impact loads, and high rotational speeds, such as automotive and machine tool fields, providing a solid guarantee for the stable operation of equipment.

Cylindrical Roller Bearings: The rollers are in line contact with the raceway, featuring large radial load-carrying capacity. Suitable for occasions bearing heavy radial loads, widely used in mechanical transmission, motors, reducers and other industries, meeting the diverse needs of customers in different industries.
