For Linear actuators, a common mechanism is to use ballscrews with ballnuts.
The ballscrew is supported at the two sides by a set of bearings which permit the rotation of the screw while keeping the axial reaction force to the ballnut movement.
Looking for those ballscrew supports, I found there are several categories:
- Floating (identified by F)
- Fixed (Identified by K)
An other letter indicate several types/shapes of supports: E, B, F, etc.
Those pieces are usually sold in a set of one fixed and one floating support:
BK + BF
EK + EF
FK + FF
I could not find understandable information about this.
What types of ballscrew/leadscrew supports exits? What is the difference between them?
