Product catalog summary

Overview
The document provides comprehensive details on Velmex's Motorized BiSlide Assemblies, emphasizing their modular, compact, and durable design. It includes examples, specifications, and customization options for various applications.

Examples and Applications
BiSlides are versatile positioning equipment compatible with NEMA size 23 and 34 motors. They are available in lengths from 5” to 80” and can be configured for applications like XY tables or parallel coupled units for large loads.

Features and Benefits
BiSlides are lightweight, cost-effective, and have a high strength-to-weight ratio. They are more compact than ball screw driven stages and feature a self-holding lead screw that resists backdriving. The anodized finish provides corrosion resistance, and the design allows for operation without lubrication.

Design and Construction
The BiSlide system is modular, allowing for easy assembly and reconfiguration. It features a precision lead screw, StabilNut for low friction, and a large carriage for versatile mounting. The base is made from hard alloy aluminum, providing strength and durability.

Specifications
The document details the load capacity, repeatability, and accuracy of the BiSlide system. It also provides guidelines for specifying a BiSlide model, including options for drive schemes, travel lengths, and mounting configurations.

Assembly and Mounting
BiSlides can be easily mounted using T-slots and cleats, allowing for multi-axis configurations. The document provides examples of mounting setups and dimensions for Series M BiSlide assemblies.

Motors and Lead Screws
BiSlides can be equipped with various motors and lead screws, with options for different resolutions and torque requirements. The document emphasizes the importance of choosing the right lead screw for specific applications.

Contamination Protection
A way cover model is available to protect the BiSlide from contamination in environments with particulate matter. This option reduces travel distance slightly but provides significant protection.

Load Handling Options
The tandem option allows for handling higher loads economically by combining a motor-driven model with a free sliding model. The parallel coupled assembly is suitable for large loads and long traverses, using a timing belt drive for synchronous operation.

Warranty and Support
The BiSlide system comes with a five-year warranty, and additional support is available through Velmex's website and customer service.

Specifications
The document details the specifications of the Motorized BiSlide and XSlide assemblies by Velmex, including dimensions, assembly components, and optional features such as the NEMA 34 two-stack double shaft step motor and T-slot plates.

Procedures
Instructions for assembling the BiSlide and XSlide systems are provided, including the use of T-slot plates, end plates, cleats, bolts, and nuts. The document specifies the recommended lengths for parallel coupled separators based on center-to-center distances.

Warranty and Standards
Velmex offers a five-year warranty on BiSlide and XSlide assemblies, covering defects but excluding misuse or unauthorized repairs. The products conform to the European Machinery Directive (89/392/EEC) Annex 1.

Features and Benefits
The XSlide is introduced as a compact version of the BiSlide, offering high precision at a lower cost. It supports various motor-driven and manual configurations, with features like integrated precision limit switches and a cleat system for secure mounting.

Key Data from Diagrams
The document includes assembly drawings and dimensions for the BiSlide and XSlide systems, highlighting the compact size and configuration options. The XSlide features a cross-section with a size 17 motor, emphasizing its compact design and adaptability for smaller loads.

Vertical application versatility is built in to every BiSlide. The end plate includes four mounting holes for attaching directly to the carriage of a horizontal assembly, or any other suitable mounting surface. For even more mountingflexibility, the standard BiSlide Assembly can be endmounted, or "sandwich" cleated to the T-Slot plate and I-beam Base profiles. This right angle drive option has a standard BiSlide sandwich cleated to the I-beam Base profile (vertical). The bottom (horizontal) surface is the T-Slot plate profile.
