Maintenance / grease / product life

Products that can not be changed to clean grease (AFF)

If "-J" is added to the end of the model, you can select the option for clean environment grease
(THK AFF Grease).
Are there any products that are not compatible?

Grease replacement for the motorized goniometer stages, the motorized rotary stages
and the motorized horizontal Z-axis stage are not possible to order with the end code.

CAVE-X (Linear Ball Guide) series ,KXT series and Slide guide series use AFF grease as standard grease,
so "-J" option code at the end is unnecessary.

Stage product life

Is there a product life of the stage? Please tell me how long they can perform without
accuracy/precision deterioration.

There is no provision for product life.
The actual usable period is difficult to estimate because it varies depending on the operating environment
(temperature, humidity, etc.), how the load is applied, and the frequency of use.

Grease-up frequency

Are there any regulations or recommendations for the frequency of grease up?

There are no regular standards, regardless of the type of grease.
Depending on the driving conditions and guide type, check the grease condition about once a month
and apply it as needed.

Grease-up method

Please tell me how to grease up.

1) Remove old grease within visible range.
2) Apply to a syringe etc.
3) Make the full stroke operation several times.
4) Wipe out any excess grease.
