Lesker Vacuum Linear Motion (Rack & Pinion) Transporter, 4.5" CF flange, 44"

Description

The vacuum system from which this was removed was clean - no radioactive or hazardous materials were contacted by the system.
Linear rack-and-pinion sample (LRP) transporter:
For both HV and UHV applications requiring in-vacuum linear motion
Available with either aluminum (ISO80 interface flange) or stainless steel (4½" CF interface flange) housings
Provides a positive-drive linear motion with standard 24" (610mm) and 36" (914mm) travel distances
A precision transporter, it features excellent wear characteristics, minimum particle generation, and precise positioning accuracy when fully extended
Uniquely suited for load lock applications
The LRP's 1" diameter extruded aluminum transfer arm with 1/2" diameter end effecter has a hardened stainless steel rack insert for strength and durability. It is driven by an aluminum bronze pinion gear. It has two diametrically opposed hardened stainless steel bearing-guide shafts that ride on a precision chamfered eight-bearing support carriage. This construction keeps the drive compact-yet ensures rigidity for heavier load transfer applications to minimize end deflection at full insertion.
This system has a manual actuator to move the transfer arm in and out.  It can be equipped with a motor drive - sold by the manufacture.
A limit switch is included. It gives a contact closure, indicating the probe is fully retracted. This signal can be interlocked to prevent the premature closing of a pneumatic-actuated gate valve through which the probe passes.
The fork on the end is a custom configuration from Lesker.
