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 6307 ZZ Bearings in Washing Machine / Dryer?
The 6307 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 6307 ZZ Bearing?
The 6307 ZZ bearing, renowned for its excellent wear resistance and load-bearing capacity, is widely utilized across multiple industries. It plays a crucial role in industrial automation equipment such as gear cutting machines and plasma cutters, automotive systems for vehicle monitoring and maintenance, metallurgy and mining for handling heavy loads in harsh conditions, oil and machinery sectors for applications like pumps and compressors, power generation in wind turbines and hydroelectric facilities, and railway industry for ensuring safe and efficient train operations. Additionally, it finds application in various other sectors including construction machinery, corrosion-resistant pumps, electronic devices, waste incinerators, and leather processing equipment, underscoring its versatility and reliability in modern industrial applications.
