Linear motion slides

Product catalog summary

Overview: The document provides comprehensive technical specifications and guidelines for Bosch Rexroth's linear motion slides, including models SGK, SOK, SGO, and SOO. These slides cater to various installation needs, with options for supported or unsupported configurations and with or without drive mechanisms.

Specifications: Linear motion slides are categorized by type, format, guideway, drive type, and size. Key specifications include maximum length (Lmax) and dynamic load capacity (C). For instance, the SGK type with a ball screw assembly can reach up to 4,000 mm in length and has a dynamic load capacity between 2,700 N and 39,180 N, depending on size.

Structural Design: The slides incorporate components like fixed and floating bearing end blocks, precision steel shafts, and super linear bushings. Optional attachments include ball screw assemblies, allowing for motor attachment via flange and coupling or a belt side drive, enhancing installation flexibility.

Technical Data: The document details dynamic characteristic values, permissible loads, and torques for each slide type and size. It stresses the importance of considering factors such as shaft deflection, drive torque, load, travel speed, and acceleration for optimal performance and longevity.

Load Capacities and Torques: Detailed tables provide load capacities and torques for different slide types and sizes, emphasizing adherence to recommended load limits to ensure desired service life.

Additional Features: Features include polyurethane protective bellows, central re-lubrication points, and various attachment parts for enhanced functionality and maintenance ease.

Drive Data: This section outlines permissible drive torque at the screw journal and guidelines for motor attachment via belt side drive or flange and coupling. It highlights the need to consider stress concentration and effective diameter reduction when determining drive torque.

Calculation Principles: The document explains service life calculation principles for linear motion systems, including linear guides, ball screw assemblies, and fixed bearings. It provides formulas for determining nominal service life in meters and hours, considering combined equivalent loads on bearings.

Drive Sizing: Drive sizing involves dividing the drive chain into mechanical and drive systems, focusing on the motor-controller combination. Technical data and formula symbols for mechanical system components are provided, emphasizing adherence to maximum permissible limits for drive torque and speed.

Key Diagrams and Tables: Diagrams and tables illustrate relationships between length, speed, and torque for different slide configurations, aiding in understanding performance limits and capabilities.

Components and Ordering: Detailed information on components such as guideways, drive carriages, motor attachments, and connectors is provided. The document specifies configurations and ordering options, including motor types and gear ratios.

Switch Activation and Safety: Instructions for determining switch activation points ensure safe operation by considering excess travel and braking distances. Recommendations for standard fittings and switch configurations are included.

Relubrication Specifications: Detailed relubrication quantities for various slide sizes and types are provided, with recommendations for grease lubrication using specific products like Dynalub 510 and Elkalub GLS 135 / N2.

Ordering Information: A detailed section on ordering linear motion slides specifies type, size, version, guideway, drive, carriage, motor attachment, and other components. An inquiry/order form is provided for customer use.

Disclaimer: The document notes that information is subject to change and does not guarantee suitability for specific applications, advising users to verify information independently.

General product description | Linear motion slides Structural design Structure of flange and coupling A motor can be attached to all linear motion slides with BASA by means of a motor flange and coupling. The flange serves to fasten the motor to the linear motion slide and acts as a closed housing for the coupling. The coupling transmits the motor drive torque free of distortive stresses to the linear motion slide shaft. Our standard couplings compensate for the system’s thermal expansion. For mounting third-party couplings, the thermal expansion must be taken into account. 4 Li near motion slides...
