Requirements for Bearings in Gear Reducer Speed Controller
A gear reducer speed controller uses at least six sets of bearings
with the following requirements:
Speed:
Motor Side: Operates at 2,800 RPM or 1,400 RPM.
Gearbox Side: Depending on the reduction ratio, operates at speeds such as
1,400 RPM, 800 RPM, 200 RPM, etc.
Temperature Range:
Operates reliably within a temperature range of -40°C to 200°C.
No Oil Leakage:
Bearings must prevent oil leakage during high-speed operation.
Excellent Dust Protection:
Effectively blocks external dust and contaminants from entering the
bearing interior.
Consistent Operation:
Bearings on the motor side must operate with consistent sound,
without any unusual noises.
What's the Performance Features of 6204 2RS Bearings in Gear
Reducer Speed Controller?
The 6204 2RS bearing is ideally suited for gear reducer speed
controllers, offering speed capability to handle motor side
operations at 2,800 or 1,400 RPM and gearbox side speeds down to
200 RPM depending on the reduction ratio. It operates reliably
within a wide temperature range of -40°C to 200°C, prevents oil
leakage with its double rubber seals (2RS), and provides excellent
dust protection. Additionally, it ensures consistent and quiet
operation without unusual noises, making it a durable and efficient
choice for gear reducer applications.
What's the Applications of the 6204 2RS Bearing?
The 6204 2RS bearing is widely used in applications requiring
reliable sealing and smooth operation, such as home appliances
(washing machines, dishwashers), office equipment (printers,
copiers), consumer electronics (electric tools, hair dryers),
industrial machinery (conveyors, pumps, fans), automotive systems
(power steering, auxiliary axles), agricultural equipment
(tractors, irrigation systems), medical devices (imaging machines,
surgical tools), power tools (drills, grinders), HVAC systems
(compressors, ventilation units), textile machinery (spinning and
weaving machines), food processing equipment (mixers, conveyors),
and exercise equipment (treadmills, ellipticals). Its double rubber
seals ensure effective protection against contaminants and reliable
lubricant retention, making it suitable for a variety of mechanical
systems.
