AI Technical Summary
The existing thrust cylindrical roller bearings suffer from uneven grease application, which affects lubrication, and lack a lateral stress relief device, resulting in a shortened service life.
A thrust cylindrical roller bearing was designed. Grease is injected through a grease gun, and uniform lubrication is achieved through the hollow structure of the input pipe and the exhaust port. Lateral forces are relieved by the movable ring and the limiting rod device to protect the roller bearing.
This allows for even application of grease, improving bearing lubrication and extending bearing life through a stress-relieving device.
