Product Storage

Post by om_tech_support_PB » Wed May 16, 2018 12:35 pm

Q: I plan to order many of your products, but store some of them away as stock until needed. In what conditions do you recommend storing your products or what steps do you recommend taking? How long can your products be stored?

A: Our products don’t have a defined shelf life. As long as they are stored under the proper conditions, they can theoretically be stored for many years. Conditions on how to store each of our products should be available in the general catalog or in the product’s operating manual. Below, you can find the general storage conditions for each type of product and the product series from which that information was obtained. If you do not see your product series listed below (i.e. if you have an AR series product), please see that product’s operating manual for storage conditions.

THK Slides
When storing the model KR, enclose them in a package designated by THK and store them in a room in a horizontal orientation while avoiding high temperature, low temperature and high humidity. After the product has been in storage for an extended period of time, lubricant inside may have deteriorated, so add new lubricant before use.

AC and Brushless DC Motors
AC Motors and Brushless DC Motors
When storing for long periods, it is recommended to coat the output shaft with an anti-corrosion agent, seal the motor in a polyethylene bag and store in a place with normal temperature and humidity.
