B4800TS Rotary Tables
B4800 is a Series of three Rotary Tables that use a worm and
gear drive design with a heavy duty central rotating ball bearing.
The tables accept NEMA size 23 stepper motors. Specifications
All tables have a hollow spindle or clear aperture for optical
applications, an 360° scale and an adjustment to minimize gear
backlash. Attaches to Series 4000 or 6000 UniSlide Assemblies with the A6000TX adapter plate. Plate
is 6" x 6" x ¼". Attaches to BiSlide with MSPP-3 plate. Download

Options and Adapters
Photo
3A Magnetic reed home switch option This switch, analogous to a limit switch on a linear stage, provides a mechanism for homing the table. You can approach it from either direction. It provides a repeatable way to return to a specific physical location. Programming for use.

Vacuum Preparation:
includes degreasing internal bearings
and re greasing with vacuum compatible grease. More details.
Anchoring table base: There are two approaches
to securing the base of the table. First, there are two clearance
holes for 10-32 UNF cap screws for attachment from above through
the top access hole.
Alternatively, to attach with screws
from below, there are four threaded holes. They are ¼"- 20
UNC - x ½" on a 4" diameter bolt circle.

Photo 7B B5990TXZ-BK adapter: Use this round plate to join two rotary tables or as an intermediate plate to hold your payload. Price and photo
400 count encoder attached to dual shaft motor provides 0.01° resolution.
Photo 7D Mounting to XSlides
There are two methods:
-- the simplest method uses 2 adapter plates.
-- alternatively, you can use a gusset. This allows you to position the Rotary table further from the XSlide if your payload extends beyond the body of the Rotary table. See XSlide Adaptors
Applications for Motor Driven Rotary Tables
Photo 8: A three axis (tilt, pan, rotate) system consisting of a motor in the base (theta 1, hidden), a tilt (theta 2), and a pan axis behind the platen (theta 3). The payload mounts on the platen. All three motors are controlled with our VXM - 3 programmable controller.

XZ adapter bracket. These tables
are used to provide for altitude and azimuth, tilt and pan
or pitch and yaw motion.

while the Velmex Model B4872TS Rotary table on the top provides
final, fine positioning. (The step motor has been removed.)
