Requirements for Bearings in Laundry Machines(Washing Machines and Dryers).
Laundry machines (washing machines and dryers) typically use two sets of bearings, with the following requirements:
Low Noise Operation:
Bearings must operate without unusual noises and maintain low decibel levels to ensure quiet operation.
Long Service Life:
Drum washing machine bearings require a very high lifespan, with a minimum of 2,500 simulated spin cycles under load and centrifugal force.
Speed Requirements:
Agitator-type washing machines: The motor speed is generally around 1,400 RPM.
Drum washing machines with BLDC motors:
No-load speed: Typically reaches 16,000 RPM.
Load speed: Around 12,000 RPM.
Variable Frequency Operation:
For models with variable frequency drives, bearings must have high durability and resistance to micro-wear to meet the stringent lifespan requirements.
What's the Performance Features of 6305 ZZ Bearings in Washing Machine / Dryer?
The 6305 ZZ bearing, featuring metal shields on both sides, is ideally suited for washing machines and dryers, offering low noise operation essential for maintaining quiet performance. Designed to endure rigorous conditions, it supports a long service life, withstanding at least 2,500 simulated spin cycles under load and centrifugal force. Capable of handling high speeds—up to 16,000 RPM no-load and around 12,000 RPM under load—it is particularly fitting for drum washing machines with BLDC motors. Additionally, its durability under variable frequency operation ensures resistance to micro-wear, meeting stringent lifespan requirements. This makes the 6203 ZZ bearing a reliable choice for the demanding environments of modern laundry machines.
What's the Applications of the 6305 ZZ Bearing?
The 6305 ZZ bearing, recognized for its high precision and excellent wear resistance, is widely utilized across various industries. It ensures stable operation and efficient machining in machine tools, handles significant loads in heavy industrial machinery, and maintains stability and safety in AC and manual welders. Its application extends to belt furnaces, where it demonstrates superior high-temperature resistance, and cleaning machinery, where it ensures effective maintenance and cleanliness. In flash dryers and rotary dryers, it enhances production efficiency and product quality, while in binding machines and ironing tables, it improves operational stability and safety. Additionally, it plays a crucial role in laboratory mixing equipment and the plastics and rubber industries, ensuring accurate results and high-quality production. Overall, the versatility and reliability of the 6305 ZZ bearing make it indispensable in numerous applications.
