Maintenance Free Rod End

A Maintenance Free Rod End is a special type of rod end that does not require lubrication or any additional sealant. These rod ends can have either an internal or external thread and are generally suitable for small to moderate rotational movements. Unlike other types of rod ends, they are largely resistant to shock and alternating loads. The two most common materials used to manufacture maintenance free-type rod ends are PTFE and chrome steel.

These maintenance-free rod ends come with a threaded shank and open bearing with no seals. They have a male right-hand thread and are usually designed to withstand heavy, constant direction loads. While they are not suitable for shock loads, they do feature low coefficient of friction and are easy to repair. The main components of a Maintenance Free Rod End are a steel/PTFE FRP sliding contact surface combination and a housing.

The Maintenance Free Rod End is available in various configurations. The most common and universal one is the Threaded Rod End. It is available with a female thread and zinc plated steel housing. The interior of this maintenance free rod end is made of PTFE-fabric and the outer ring is made of steel. These maintenance-free rod ends are characterized by their low coefficient of friction and high load capacity. The maintenance-free Rods have the advantage of being corrosion-resistant and lubricated.

Maintenance-Free Rod Ends are available in two variations: the open bearing and the threaded shank. The latter type has an internal spherical plain bearing that has a low coefficient of friction. These rod ends are limited in their shock and alternating load capacities. The housing is zinc plated, and the sliding layer is made of PTFE-fabric. This type of rod end can be used in a wide range of applications, including hydraulic systems.

The maintenance-free Rod End has a threaded shank. The internal spherical plain bearing has no seals. The cylindrical shape of this rod end makes it suitable for shock loads and heavy constant direction loads. The open bearing is usually made of steel. The housing is galvanized. A Maintenance-Free Rod End is an open bearing that has a low coefficient of friction. The external spherical plain bearing has low friction.

INA joint bearings require lubrication for their long-term service. They offer radial, angular contact, and axial bearings. In addition, they can also be used in heavy alternating loads. In addition, the maintenance-free Rod End is the most reliable type of Rod End. They are available in a wide range of sizes. Its main component is a spherical plain bearing that has an external threaded shank.


INA joint bearings are maintenance-free rod ends. They feature an open bearing with no seals. They are also corrosion-resistant and reduce friction. The INA joint bearings provide axial and angular contact with the shaft. These rod ends are also available with threaded shanks. These maintenance-free Rod Ends have two components: a housing with a threaded shank and a spherical plain bearing. The PTFE FRP sliding layer is attached to the housing.

INA joint bearings are maintenance-free rod ends that do not need to be lubricated. This type of Rod End is ideal for axial and angular contact loads. It has a spherical plain bearing, which is lubricated. PTFE is also corrosion-resistant. Its spherical plain bearing is galvanized. The INA joint-free rod ends are the most reliable rod ends in a variety of applications.

Maintenance-Free Rod Ends are manufactured with a threaded shank and an open bearing without seals. They are suitable for constant direction and alternating loads, but they are not recommended for shock or alternating loads. These Rod Ends have a spherical plain bearing inner ring and a sliding layer of PTFE FRP with PTFE. These are the best choice for heavy duty applications.

A Maintenance-Free Rod End is a rod-end that has no seals and requires no lubrication. The open bearings have a low coefficient of friction and are suitable for continuous loads. However, they have limited shock and alternating load capabilities. They have a spherical plain bearing inner ring and are a combination of steel and PTFE FRP. They are suitable for alternating loads but do not allow axial or radial asymmetrical load.
