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 6309 2RZ Bearings in Gear Reducer Speed Controller?
The 6309 2RZ 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 6309 2RZ Bearing?
The 6309 2RZ bearing, widely used in agricultural machinery like harvesters and irrigation systems, construction equipment such as excavators and loaders, and material handling conveyor systems, it ensures smooth and reliable operation under heavy loads and challenging conditions. This bearing also plays a critical role in automotive components including power steering and blower motors, industrial fans and blowers for efficient airflow management, pumps for handling various fluids, and food processing equipment that requires frequent washdowns and strict hygiene standards. Its ability to handle moderate radial and axial loads, combined with low noise and durable sealing, makes the 6309 2RZ bearing indispensable across multiple industries.
