1. Lubrication Guidelines
Application Guidelines-Example of Lubrication

All Tolomatic actuators are prelubricated at the factory. To ensure maximum actuator life, the following guidelines should be followed:

  • Filtration: We recommend the use of dry, filtered air in our products. "Filtered air" means a level of 10 Micron or less. "Dry" means air should be free of appreciable amounts of moisture. Regular maintence of installed filters will generally keep excess moisture in check.
  • External Lubricators (optional): The factory prelubrication of Tolomatic actuators wil provide optimal performance without the use of external lubrication.

However, external lubricators can further extend service life of pneumatic actuators if the supply is kept constant. Oil lubricators, (mist or drop) should supply a minimum of 1 drop per 20 standard cubic feet per minute to the cylinder. As a rule of thumb, double that rate if water in the system is suspected. Demanding conditions may require more lubricant. If lubricators are used, we recommend a non-detergent, 20cP @ 140oF 10-weight lubricant. Optimum conditions for standard cylinder operation is +32o to +150oF (+0o to 65.5oC). NOTE: Use of external lubricators may wash away the factory installed lubrication. External lubricants must be maintained in a constant supply or the result will be a dry actuator prone to premature wear.

  • Sanitary enviroments: Oil mist lubricators must dispense "Food Grade" lubricants to the air supply. Use fluids with ORAL LD50 toxicity ratings of 35 or higher such as Multitherm® PG-1 or equivalent. Demanding conditions can require a review of the application.
