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 6304 Bearings in Gear Reducer
Speed Controller?
The 6203 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.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 6304 Bearing?
The 6304 bearing, is widely utilized across multiple industries due
to its simple structure, ease of use, and ability to handle both
radial and axial loads. It plays a crucial role in industrial
machinery, automotive applications, aerospace components,
agricultural equipment, and electrical devices, ensuring high
precision, reliability, and stable performance even under extreme
conditions. Proper maintenance, including regular inspection and
timely replacement of worn parts, is essential for extending its
lifespan and maintaining efficient operation.
