they are divided into two types: with single bar and with double bar.
When you are looking for an easy-to-assemble solution, linear axes with double bars are the right answer (AD, AG, AV series). They have a central aluminum body which acts as a supporting structure for the two hardened, ground and chromed steel bars. The advantage is to use a product with already excellent parallelism between the two bars. The good resistance to wear is given by the use of the two steel bars mentioned above.
Joints can be made on the linear axes of the AD and AG series to obtain guides longer than 6 m. There is no limit to the length that can be made.
Linear axes with single bar are used when the application requires a different bar center distance: either wider to obtain greater stability or narrower to reduce overall dimensions. It is the customer's responsibility to correctly parallel the two single linear modules by following the instructions given on the AS product catalog page.
Our technical office is always available to help the customer in choosing the most suitable linear module for the application and for suggestions regarding the most suitable type of fixing.
