Product features of ZYS deep groove ball bearing:
Bearing inner and outer ring: The inner ring, outer ring and rolling elements of the bearing form an organic rotating unit. The inner and outer rings of ZYS deep groove ball bearings are made of GCr15 high-quality steel. The steel has high density and good ductility, which effectively prolongs the service life of the bearing.
Bearing rolling elements: The rolling elements transfer the load between the inner ring and the outer ring. ZYS deep groove ball bearings use G10 national standard steel balls to ensure stable operation and low noise.
Bearing cage: The bearing cage can reduce the frictional heat, optimize the load, keep the rolling elements in the correct position and interval, and prevent the rolling elements from falling off during installation. ZYS deep groove ball bearings use steel stamping cage or brass solid cage.
Bearing seal:
ZYS can provide deep groove ball bearings with different sealing structures, including open type (No shields), ZZ type (Metal shields), 2RS type (Contact rubber seals), 2RZ type (Non-contact rubber shields).
RS type (Contact rubber seals): The rubber seal material can effectively prevent foreign matter (liquid state) and impurities from intruding into the bearing and causing internal damage to the bearing. It has a good mute effect and is suitable for harsh environments.
ZZ type (Metal shields): The sealing material is stainless steel, which can effectively prevent external impurities from invading the bearing and causing internal damage to the bearing. It has low friction resistance, fast heat dissipation, high temperature resistance, high speed, and it is suitable for relatively clean working conditions.
Open type (No shields): The steel ball can be seen directly without a seal, which is suitable for a sealed environment such as a gear box and an environment with a lot of oil. The friction resistance is small, the idling effect is good, and the speed is super high.

MOTORCYCLE

Each motorcycle is usually equipped with 20 to 30 bearings. These bearings are used for important rotating parts such as engines, transmissions, and wheels to support driving, and are responsible for reducing friction and driving the engine power to the wheels. Therefore, the performance required for motorcycle bearings is to achieve smooth rotation through low friction, low vibration and high durability. These performance affect the fuel consumption and safety that are closely related to our life. ZYS always pays attention to these details and strives to develop bearing and optimize the bearing design to improve the quality of life and protect the global environment.
