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 6306 ZZ Bearings in Washing Machine / Dryer?
The 6306 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 6306 ZZ Bearing?
The 6306 ZZ bearing, known for its durability and sealed design, is widely utilized across various sectors. In industrial manufacturing, it supports rotating components in machinery like plate rolling machines and dehydration equipment, reducing friction and ensuring smooth operation. Within the automotive industry, it handles radial and axial loads in critical parts such as engines and transmissions, ensuring efficient vehicle performance. For the chemical industry, its corrosion-resistant coating and sealed design make it suitable for harsh environments, applicable in equipment like plastic pelletizing machines and injection molding components. In agriculture, it provides reliable support in machinery such as tractor water pumps and gearboxes, enhancing the efficiency of agricultural operations. Additionally, in commercial settings like Western restaurants, it ensures smooth operation in food processing and refrigeration equipment. Overall, the 6306 ZZ bearing's robust performance and versatility make it indispensable in multiple industries.
