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 6902 2RS Bearings in Gear Reducer Speed Controller?
The 6902 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 6902 2RS Bearing?
The 6902 2RS bearing,idely used in precision instruments, medical devices such as portable diagnostics and surgical tools, office equipment like printers and scanners, consumer electronics including smartphones and tablets, and automotive components such as electric motors and power window mechanisms, this bearing ensures reliable and smooth operation in compact and lightweight designs. Its small size makes it indispensable for precise and portable technologies, facilitating efficient performance in devices that require minimal footprint and weight.
