Rollico
In many machines, it is the linear bearings that are responsible for smooth motion, stable guidance and repeatable operation. Their correct selection and conscious service handling have a direct impact on the reliability of the entire application.
A linear bearing should be treated not only as a guiding component, but also as part of the maintenance system. Its service life is determined not only by the product type, but also by operating conditions, lubrication and service accessibility.
Rollico materials indicate three practical aspects: the bearings are pre-lubricated, they can be additionally lubricated to extend operating life, and in selected solutions lubricant can be supplied through the housing with a lubrication hole.
SKF LGMT 2/0.4 is indicated as the recommended lubricant.
Initial lubrication facilitates system start-up, but in applications operating for long periods, intensively or under more demanding conditions, the possibility of relubrication should be considered.
Load, speed, contamination, temperature and cycle frequency affect how quickly rolling elements and guideway raceways wear.
If the machine operates in continuous duty, it is worth designing the system so that service activities are as quick as possible and do not require extensive disassembly.
| Message element | Meaning for maintenance | Practical decision |
|---|---|---|
| Pre-lubrication | The bearing is prepared for operation and does not require start-up lubrication each time. | However, it is worth checking whether the application conditions require an additional lubrication plan. |
| Optional relubrication | Additional lubrication can extend the service life of the system and reduce the risk of dry running. | A good solution is to include periodic lubrication in the maintenance schedule. |
| Lubrication hole in the housing | Facilitates grease application without complicated disassembly of machine components. | During design, it is worth ensuring easy access to lubrication points. |
| SKF LGMT 2/0.4 | Indicated as the recommended lubrication product. | The compatibility of the lubricant with the operating conditions and the machine operating manual should be verified. |
The best results are achieved by combining the correct selection of a linear bearing with a simple, repeatable maintenance procedure. If the system is to operate for a long time and remain stable, lubrication should not be a random activity, but part of planned maintenance.
