Model Meaning Analysis
The model code of Airtac slide cylinder HLS8X20AS follows the unified rules of Airtac HLS series. The meaning of each character is analyzed as follows, which accurately corresponds to the core parameters of the product:
HLS: รหัสซีรีส์, representing Airtac dual-axis precision slide cylinder (roller type, ประเภทมาตรฐาน). Its core features are dual-axis guidance and roller guide rail structure, with high-precision positioning performance, suitable for precision transmission scenarios;
8: Bore size, unit is mm, นั่นคือ, the bore diameter of the slide cylinder is 8mm, which determines the output thrust of the cylinder and corresponds to the load capacity within the working pressure range;
20: Stroke specification, unit is mm, นั่นคือ, the effective stroke of the cylinder slide is 20mm, referring to the maximum displacement of the slide from the retracted state to the extended state;
AS: Function suffix, representing the front-end stroke adjustment screw, which can precisely fine-tune the stroke of the cylinder’s extended end to adapt to positioning needs in different scenarios. It is different from the basic model without stroke adjustment (ส) and the rear-end stroke adjustment model (ของ).
- Applicable Operating Environment
This slide cylinder is an industrial-grade precision pneumatic component, suitable for most automation scenarios. The specific operating environment parameters and requirements are as follows, combined with product characteristics and industry standards:
Temperature Range: The normal working temperature is -20~70℃. If high-temperature sealing materials are used, it can adapt to high-temperature working conditions up to 150℃. Avoid using it in ultra-high temperature environments to prevent aging of sealing parts and movement failure;
Working Pressure: 0.15~0.7MPa. Dry and clean compressed air must be connected. Avoid excessive pressure to damage cylinder components, and insufficient pressure will affect output thrust and movement speed;
Interface Specification: The interface caliber is M5×0.8, which is suitable for corresponding specifications of pneumatic connectors to ensure air tightness and avoid air leakage affecting movement accuracy;
ข้อกำหนดด้านสิ่งแวดล้อม: Suitable for industrial environments without strong corrosive gases, a large amount of dust, and severe vibration (such as electronic equipment assembly, small mechanical processing, automatic assembly lines, ฯลฯ); avoid long-term use in humid, salt spray, and strong electromagnetic interference environments. If it is necessary to adapt to harsh environments, additional protective measures must be taken; the humidity is controlled at 0~99% non-condensing state to prevent rust of internal components;
ข้อกำหนดในการติดตั้ง: Three installation methods can be realized: horizontal (body tapped bottom lock, body through hole top lock) and vertical (body tapped). When installing, the screws must be tightened according to the specified torque (HLS8 model is suitable for M3×0.5 screws, maximum tightening torque 1.2Nm) to avoid positioning deviation caused by loose installation.
III. Comparison/Alternative Models of Other Brands
As a precision slide cylinder with 8mm bore diameter, 20mm stroke and front-end stroke adjustment from Airtac, HLS8X20AS can be directly replaced with the following models of the same specification from well-known brands. The core parameters (bore diameter, stroke, stroke adjustment function, installation size) are consistent, suitable for general pneumatic systems:
SMC (ญี่ปุ่น): MXS8-20AS, which also belongs to dual-axis slide cylinder with roller guide rail structure and front-end stroke adjustment function. It has 8mm bore diameter and 20mm stroke, and its installation size is compatible with HLS8X20AS. Its precision and service life are equivalent to those of Airtac models, suitable for high-end automation scenarios;
Festo (เยอรมนี): DGSL-8-20-P-A, dual-axis precision slide cylinder with 8mm bore diameter, 20mm stroke and front-end stroke adjustment function. Its protection level and movement precision are slightly higher, which can directly replace HLS8X20AS, suitable for industrial scenarios with high precision requirements;
CKD (ญี่ปุ่น): STS-B-8-20-AS, double-acting slide cylinder with 8mm bore diameter, 20mm stroke and front-end stroke adjustment function. It has a compact structure and its installation size matches HLS8X20AS, which can be used as an alternative model, suitable for small and medium-sized automation equipment;
Domestic Alternatives: E.MC ESL8X20AS and CHELIC MHL8X20AS, both designed imitating Airtac HLS series, with consistent core parameters and higher cost performance, suitable for cost-sensitive scenarios.
- Official Order Number
The official standard order number (original factory code) of Airtac slide cylinder HLS8X20AS is: 1527935-AS (corresponding to 8mm bore diameter, 20mm stroke, AS suffix front-end stroke adjustment model);
หมายเหตุเพิ่มเติม: When placing an order, the full model name (HLS8X20AS) and order number must be clearly specified to avoid confusion with the basic model (HLS8X20S, order number 1527935); if supporting installation accessories (such as mounting plates, connectors, travel switches) มีความจำเป็น, you can consult Airtac official or authorized distributors separately to obtain the corresponding accessory order numbers to ensure compatibility of supporting use. Some distributors may mark it as “HLS8X20AS-Genuine Original Factory”, and the core order code remains unchanged.
