  • Documentation & Part No.

The PPS-28 Linear Motor version is suitable for applications requiring very fast speeds. Miniature crossed roller bearings assure high stiffness and guiding accuracy for loads up to 50 N (horizontal orientation). Closed loop resolution of 2 nm is achievable. The PPS-28LM is compatible with the MMC-300 controller.
