Slow SMC rodless cylinderIntroduction to rodless cylinder products
1、 Product Overview
SMC MY1B isMechanical joint rodless cylinder foundation modelAbandoning the traditional cylinder piston rod structure, adopting a rigid mechanical connection structure between the piston and the external sliding table, relying on an integrated sliding table and a piston full stroke through design, combined with an inner layer of pressure retaining sealing tape and an outer layer of dust-proof and anti fouling sealing tape, to create a low profile, ultra compact body structure. The product supports ultra long stroke operation, adapts to multiple installation scenarios, is lightweight and low loss, and can meet the linear drive needs of industrial automation for long stroke and medium load. It is a versatile linear transmission pneumatic component.
This cylinder supports lubrication free operation, with a working temperature range of+5 ℃ to+60 ℃, a rated pressure resistance of 0.8MPa, and a ZUI low working pressure of only 0.10-0.15MPa. It is suitable for various high and low speed operating conditions and comes standard with an air buffer structure. It also supports the selection of external hydraulic buffer units, ensuring stable operation and strong adaptability. It is widely used in various automated production line equipment.
2、 Working principle and core structure
1. Overall structural composition
The core structure of MY1B rodless cylinder includes six major components: a long aluminum alloy cylinder barrel, a double-layer sealing belt, a piston assembly, a mechanical connection frame, an external load-bearing slide table, and a buffer component. The aluminum alloy cylinder barrel is equipped with a long strip of motion opening, which relies on a built-in metal connecting claw to penetrate the sealing belt, rigidly locking the internal piston and external sliding table to achieve integrated linkage; The double-layer sealing tape is responsible for internal air pressure sealing and external environmental dust prevention, ensuring the continuous and stable operation of the equipment.
2. Operating principle
The product is powered by compressed air and achieves linear reciprocating motion through air path reversal: compressed air enters from one end of the cylinder through an air port and exits from the other end, creating a pressure difference inside the cylinder and pushing the piston to slide axially; The piston drives the external load-bearing slide table to move synchronously without any gap through a rigid mechanical connection structure; Switching the direction of the gas path can complete the return reset.
During the operation of the equipmentPartial opening, full area sealingMechanism: The inner sealing tape is only partially opened at the piston movement position, and the rest of the area is fully sealed to lock the internal air pressure and prevent air leakage; The outer dust-proof sealing tape fully seals the opening of the cylinder body, effectively blocking dust, iron filings, and impurities, and protecting the internal precision structure. At the same time, the buffer structure at both ends can effectively reduce the impact at the end of the stroke, and lower the vibration and noise of the equipment.
3、 Core advantages of the product
1. Compact structure, lightweight upgrade
Integrated design without piston rod significantly reduces equipment installation space, resulting in a low profile and compact size of the body. Compared to its predecessor, the ø 25-40 cylinder bore model can achieve a maximum load weight of 5.8-9.9kg under a 1000mm stroke, with an overall weight reduction of 13-17%. The lightweight body can reduce equipment load losses.
2. Strong adaptability and flexible installation
The cylinder head piping has been upgraded from traditional 3-directional to 4-directional, and the piping method can be flexibly changed on site as needed; The magnetic switch adopts a front mounted design, which can be adjusted at any position in the slot, greatly reducing installation time. Supports four installation methods: horizontal, vertical, top, and wall, with two fixing schemes: bottom T-slot and two fixed ends, suitable for various equipment installation spaces.
3. Durable protection, upgraded lifespan
Optimize the fixed structure of the dust-proof sealing strip, combined with an inner and outer double-layer staggered sealing structure, to balance pressure holding performance and dust-proof and anti fouling capabilities. It can adapt to complex industrial working conditions, effectively avoid problems such as air leakage and impurity intrusion, and significantly extend the service life of the equipment.
4. Adjustable performance and stable operation
Standard air buffer structure, with a buffer needle valve placed on top for easy debugging and operation; Optional A/L/H external hydraulic buffer units are available, suitable for different load conditions such as low, medium, and high. The operating speed range of the equipment is wide, with a speed of 100-1000mm/s under the condition of no stroke adjustment bolt, and can reach up to 1500mm/s with external shock absorbers, meeting the requirements of high-frequency, high-speed, and smooth linear transmission.
5. Strong scalability
Supporting the combination of floating brackets, lateral supports, and external linear guides, it can effectively solve the problems of warping and sagging of long stroke cylinder tubes, compensate for installation errors, and improve the accuracy and stability of long-distance operation.

VISlow SMC rodless cylinderSelection and installation points
1. Selection criteria
The selection requires comprehensive calculation of load mass, static torque, and impact torque. The total load rate should be ≤ 1, and the recommended optimal load rate should be ≤ 0.5; The buffering capacity needs to be carefully checked for vertical and downward operating conditions. When there is a significant impact at the end of the stroke, an A/L/H hydraulic buffering unit must be selected; When the device requires an intermediate stop function, it needs to be equipped with a center pressure type three position valve and a double-sided pressurization circuit to prevent displacement drift.
2. Installation specifications
Support multi-dimensional installation and adapt to various device structures; When the cylinder stroke exceeds 2000mm, an intermediate support structure needs to be installed to prevent the cylinder from sagging or warping; Long range equipment is recommended to be equipped with lateral supports and floating brackets to compensate for installation errors and improve operational accuracy and stability. Magnetic switches need to be matched with D-M9 □/D-A9 □ series models according to the voltage and output type of the equipment control circuit.
