Requirements for Bearings in Washing Machine /Dryer.
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 6204 ZZ Bearings in Washing Machine/ Dryer.
The 6202 ZZ bearing is well-suited for washing machines and dryers, offering quiet operation with low decibel levels, a long service life enduring at least 2,500 simulated spin cycles under load, and high-speed capability supporting speeds up to 16,000 RPM for no-load and around 12,000 RPM under load. Its metal shields provide effective protection against contaminants and ensure efficient lubrication retention, enhancing durability and resistance to micro-wear in variable frequency drive applications. This makes it reliable and efficient for the demanding operations of modern laundry machines.
What's the Applications of the 6204 ZZ Bearing?
The 6204 ZZ bearing is widely applied in home appliances, industrial equipment, automotive systems, office machinery, medical devices, and tools, offering quiet operation, effective contamination protection, and moderate load capacity. It supports drum rotation in washing machines, ensures smooth conveyor belt movement, facilitates efficient pump shaft operation, and provides reliable performance in electric motors and power steering systems. Additionally, it ensures precise operation in office equipment and durable function in power tools and lawn equipment, making it an essential component for applications requiring dependable, low-maintenance, and quiet performance.
