Product Details Supplier Info More products

Aerotech’s APR mechanical bearing series is suitable for precise rotary positioning in applications such as precision component testing, optical calibration systems, laser micromachining, sub-micron metrology, slip ring assemblies, laser feeds and air supplies.

The units feature an accuracy of up to 1.5 arc-sec and an axial load capacity up to 450kg.

Within the range there are seven models in three frame sizes with nominal square footprint mounting dimensions of 150, 200 and 260mm, and a clear through-aperture of 50, 75, or 100mm respectively.

The series also features a cog-free, direct-drive, brushless servo motor that has rapid acceleration and a maximum speed of up to 800rpm at the smaller stage.
