MarMotion high-precision rotary stroke bearings require virtually no maintenance. They are treated with anticorrosive agent before dispatch. After delivery, this agent must be removed, preferably with a cleansing agent containing oil. The rotary stroke bearing is then ready for operation.
In principle, the same rules apply here as for ball bearings. A thin film of lubricant will last for long-term operation, depending on the type of loads acting. Commercial "rolling bearing lubricants" - only this type of lubricant may be used - possess all the properties required to ensure the trouble-free operation of rotary stroke bearings.
In such cases, designs in stainless rolling bearing steel 1.4112 (special design) offer distinct advantages.
Assuming the maintenance instructions are observed, the wear suffered by rotary stroke bearings is so slight that it can be ignored.
With a high number of linear strokes or rotations, the causes mentioned above can lead to rapid spoiling of the rolling faces. Wherever wear marks are perceived, the cause of the problem must be thoroughly eliminated.
Open or only partially protected rotary stroke bearings are best serviced through regular cleaning and lubrication performed within the scope of general maintenance work. This improves the working properties and service life of the rotary stroke bearings.
