High-Precision Incremental Linear Scales
With high repeatability and defined thermal expansion, the LF 485 and LF 185 incremental linear scales offer increased precision on high accuracy machine tools, jig bore and grinding machines, and linear motors. From a grating period of 8µ, the LF produces scanning signals with a period of 4µm, allowing accuracy grades as fine as ±2µm.
The LF 485 and LF 185 encoders are highly rigid in the measuring direction, and the low mass of components moved exceeds the dynamic behavior of its predecessor, the LF 183. Design of the scales also correspond with Heidenhain’s LS and LC linear scales, which feature the same mounting dimensions. The LF 485 can also replace the LF 481, the LS 487, or the LC 415.

Minimal Pitch Deviation for Maximum Precision
In the case of rotary drive tasks, the conversion and optimal adaptation of mechanical torques to the respective application usually occurs by means of finely graduated reduction gearheads. High-precision lead screws, in combination with DC micro-motors, brushless DC servomotors, or stepper motors also make it possible to convert the rotational movement into linear stroke or tensile movements.
Enter the BS22-1.5 spindle drive from the Faulhaber Group, where the use of ball screws in the series BS 22-1.5 enables linear movements with minimum travel variations of a maximum of 5μm over the absolute total travel. In combination with motors and mounted components, such as high-resolution encoders, integrated motion controllers, or stepper motors in micro-stepping operation, maximum precision is ensured. This is ideal for demanding positioning tasks such as optical filters, glass-fiber technology, lens adjustment in optical systems, or micro-actuators for medical technology. Implementation of the mechanical connection to the motors is by means of a backlash-free coupling integrated into the lead screw. Numerous modifications, such as variable screw lengths, modified screw nuts, and custom lubricants are available on request for use in special applications.
