About this file
This document is a Request for Proposals (RFP) for three types of linear motion stages from Zaber, with specific technical requirements for each stage. The requirements include three linear stages: a vacuum-compatible 100 mm stage (LSM100B-V1T4), a standard 100 mm stage (LSM100B-T4A), and a 50 mm stage (LSM050A-T4A). Common specifications across all stages include stepper drive type, no controller, no encoder, M3 mounting holes with 20 mm grid spacing, and specific performance metrics such as maximum continuous thrust, accuracy, repeatability, and backlash. Each stage has unique requirements for overall height, width, length, speed, and motion range, with FFDG reserving the right to determine equivalency for alternative manufacturers. The document requests vendors to provide lead times for delivery and allows for less restrictive deviations from the Zaber specifications.

We are looking to purchase three types of linear stages. The specifications are listed in the following three sections.
Stage # 1: Vacuum-compatible 100 mm Linear Stage We are looking for a vacuum-compatible 100 mm linear motion stage, Zaber part number LSM100B-V1T4 or equivalent a. At a minimum, the specifications in the following table must be met. Please provide the lead time for delivery.
Vacuum compatibility level 10-3 Torr or better Drive type Stepper No controller No encoder Stage mounting hole size and spacing M3 with 20 mm grid spacing Maximum overall height <= 22 mm Mounting height <= 22 mm Mounting area b > 20 mm x 20 mm Accuracy (unidirectional) <= 45 m Repeatability < 6 m Backlash < 16 m Maximum continuous thrust >= 25 N Pitch, Yaw, Roll stiffness b < 350 rad/Nm Maximum overall width b < 110 mm Minimum overall width b > 25 mm Maximum overall length b < 350 mm Maximum speed b >= 25 mm/s Minimum speed b < 1 mm/s Maximum motion range b 100 – 105 mm a FFDG will be the sole determiner of equivalent.
b Deviation from Zaber LSM100B-V1T4 that is less restrictive.
Stage # 2: 100 mm Linear Stage We are looking for a 100 mm linear motion stage, Zaber part number LSM100B-T4A or equivalent a. At a minimum, the specifications in the following table must be met. Please provide the lead time for delivery.
