Platform Cylinder Series CXT

Product catalog summary
Overview: The document outlines a precision slide table integrated with an actuator, designed for applications requiring high accuracy and load handling. It features two types of guide rod bearings: slide bearings for heavy loads and ball bushing bearings for smooth operations.
Specifications: The slide table is available in series CXT12 to CXT40, supporting maximum movable weights from 3kg to 50kg. Specifications include allowable static weight, table displacement, bore sizes, and stroke lengths for both slide and ball bushing bearings.
Features: The slide table can be mounted on two sides and includes an adjustment bolt with a bumper for stroke adjustments of 5mm on each side. Optional shock absorbers and auto switches are available. Mounting options are provided from both the bottom and upper sides.
Operating Conditions: The cylinder operates with air, is double-acting, and has a proof pressure of 1.5MPa. It functions within a temperature range of -10 to 60°C and a piston speed of 50 to 500mm/s. Lubrication is not required, and the stroke is adjustable.
Shock Absorber Specifications: Details include theoretical force, maximum absorbed energy, absorbed stroke, collision speed, and operating frequency. Guidelines for model selection based on mounting conditions, weight, pressure, and speed are provided.
Installation and Operation Precautions: Ensure flatness of the mounting surface, avoid damage to the piston rod and guide shaft, and do not apply excessive load or shocks. Instructions for changing port direction and maintaining bearings with periodic greasing are included.
Selection Procedures: Guidelines for selecting the appropriate bearing style and model consider impact load, vibration, accuracy, and smooth operation. Calculations for resistance force, theoretical output, and load ratio are included.
Specifications and Installation: The cylinder's orientation can be adjusted in 90° increments. Flush piping before installation to prevent debris. Adjustment bolt and shock absorber positions are fixed; contact SMC for inversion.
Shock Absorbers and Load Handling: RB Series shock absorbers handle a wide energy range without adjustment. Protect the shock absorber rod from scratches and ensure loads do not exceed calculated values.
Operation and Maintenance: Adjust the damper at stroke ends to prevent damage. Load weight and speed are limited when using only the adjustment bolt. Periodically grease slide block bearings with lithium soap grease.
Load and Moment Specifications: Tables provide maximum movable weight and allowable moments for different bore sizes and bearing types. Align the load's center with the slide block's center to avoid shock loads.
Component and Material Details: A detailed parts list includes materials like aluminum alloy, carbon steel, and stainless steel. Replacement parts are specified with ordering numbers.
Auto Switch Specifications: Details on auto switch models and wire specifications are provided. Ensure proper connection and observe polarity for switches with indicator lights.
Handling Precautions: Avoid dropping or impacting the product and operating in areas with strong magnetism. Contact SMC if magnetic interference affects auto switch operation.

Platform Cylinder Series CXT-1

Platform Cylinder A highly rigid and highly accurate slide table integrated with an actuator. Two styles of guide rod bearings to accommodate your application Slide bearing—for heavy loads Ball bushing bearing—for highly accurate and smooth operation Auto switches can be installed. A shock absorber can be installed (option). Can be mounted on two sides. Mounting from upper side Mounting from bottom side Guide of high rigidity Adjustment bolt with bumper is standard. Performs the function of a cushion and adjusts the stroke 5mm on each side, or 10mm for both sides. For moving and transporting workpieces. For moving the receptacle for workpieces used in stamping or press-fitting processes. For using as a P&P unit in combination with other actuators. CXTM (Slide bearing) CXTL (Ball bushing bearing) Allowable Table static weight displacement (kg) (mm) Allowable static weight (kg) Note 1) "Table displacement" is the amount of deflection of the guide rod that occurs when a maximum load weight is placed on the maximum stroke table while the table is at the center of the stroke (the amount of looseness Note 2) Allowable static load is not included). Note 2) An "allowable stationary weight" is the allowable amount of stationary weight that can be applied vertically to the workpiece mounting surface of the table while the table is at the stroke end.
