SMC CDM2B25-300Z Pneumatics Air Cylinder (CDM2B25300Z)<\/h1>\n
<\/div>\n
The SMC CDM2B25-300Z (also designated as CDM2B25300Z) is a double-acting, single-rod air cylinder from SMC\u2019s CM2 – Z series, designed for industrial automation applications requiring stable linear motion with a 25 mm bore and 300 mm stroke. It is a basic – type (double – side bossed) actuator with rubber cushioning, male rod – end thread, and no rod boot, featuring a built – in magnet for easy auto – switch installation. This cylinder is widely used in material handling, packaging machinery, and automated assembly lines, as it integrates easily with pneumatic control systems and various mounting brackets, ensuring reliable performance and long service life.<\/div>\n

Function<\/th>\nDetailed Description<\/th>\n<\/tr>\n<\/thead>\n
Double – Acting Linear Motion<\/td>\nConverts compressed air pressure into bidirectional linear force (extension and retraction) for automated cyclic operations, suitable for continuous – motion tasks in production lines.<\/td>\n<\/tr>\n
Built – in Magnetic Position Feedback<\/td>\nThe piston has an integrated magnetic ring, enabling the installation of magnetic proximity sensors to provide real – time position feedback for system synchronization and safety interlocking.<\/td>\n<\/tr>\n
Rubber Cushioning Protection<\/td>\nComes with non – adjustable rubber cushions at both stroke ends to absorb impact, reduce operational noise, and prevent damage to the cylinder and connected equipment during rapid stops.<\/td>\n<\/tr>\n
Flexible Mounting<\/td>\nThe basic – type (double – side bossed) design allows for easy installation with single clevis, trunnion pivot brackets, etc., adapting to multiple installation orientations like horizontal and vertical.<\/td>\n<\/tr>\n
Precision Positioning<\/td>\nIts stable structure and optimized sealing system ensure consistent stroke accuracy, meeting the positioning requirements of general industrial automation tasks.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

Technical Features<\/h3>\n
<\/div>\n
    \n
  1. Durable Construction<\/strong>: The cylinder barrel is made of stainless steel for excellent corrosion resistance, and the piston rod is stainless steel (SUS304) with a hard – chrome plating, enhancing wear resistance and load – bearing capacity.<\/li>\n
  2. Reliable Sealing<\/strong>: High – performance NBR rubber seals are used to minimize air leakage, maintaining stable pressure and consistent performance at the maximum operating pressure, with an option for Viton seals for high – temperature applications.<\/li>\n
  3. Broad Operating Range<\/strong>: Operates reliably within an air pressure range of 0.15-1.0 MPa and an ambient temperature of – 10\u00b0C to 60\u00b0C, suitable for typical industrial working environments with a relative humidity \u2264 85%.<\/li>\n
  4. Easy Auto – Switch Adjustment<\/strong>: The design facilitates fine – tuning of the auto – switch position, simplifying setup and reducing downtime during maintenance.<\/li>\n
  5. Cost – Effective Operation<\/strong>: It is oil – free lubrication compatible, which lowers operational costs and makes it suitable for clean environments such as electronic component assembly lines.<\/li>\n
  6. Versatile Port & Thread Design<\/strong>: The Rc port thread and male rod – end thread allow for easy connection to air hoses and mechanical components without additional adapters.<\/li>\n<\/ol>\n
