Requirements for Bearings in Planetary Gearboxes.
Planetary gearboxes generally require three sets of bearings to support their high-speed operation, often reaching speeds above 3,000 revolutions per minute (RPM). The key performance features of these bearings include:
No Oil Leakage:
Designed to prevent oil leakage even during high-speed operation, ensuring reliable lubrication and extending the service life of the gearbox.
Dust Protection:
Provide excellent sealing to block external dust and contaminants from entering the internal components, maintaining optimal performance and reducing wear.
Low Noise Operation:
Operate quietly with minimal noise and vibration, contributing to smooth and efficient gearbox operation.
What's the Performance Features of 6311 2RS Bearings in Planetary Gearboxes?
The 6311 2RS bearing, with its double rubber seals, is well-suited for planetary gearboxes, providing reliable performance at high speeds exceeding 3,000 RPM. It effectively prevents oil leakage, ensures dust protection to maintain internal cleanliness, and operates with low noise and minimal vibration, contributing to the smooth and efficient operation of the gearbox. Its robust design enhances durability and extends service life, making it an ideal choice for the demanding conditions of planetary gearboxes.
What's the Applications of the 6311 2RS Bearing?
The 6311 2RS bearing is widely used in heavy machinery such as construction equipment and agricultural vehicles, industrial equipment like large conveyor systems and heavy-duty pumps, automotive components including wheel hubs of larger vehicles, wind turbines for nacelle and pitch control systems, and railway vehicles for axle boxes. Its capability to handle substantial radial and axial loads, along with effective protection against dust and moisture, makes it an essential component in industries demanding durable and low-maintenance solutions.
