FHLS, FHLSL Series Double Shaft Precision Slide Cylinder (Roller Type)

·Before the cylinder is connected to the pipeline, the dirt inside: the pipeline must be cleared to prevent foreign objects from entering the cylinder.
·The medium used in the cylinder should be filtered through a filter element with a pore size smaller than 40um before use.
·In low-temperature environments, anti-freezing measures should be taken to prevent the water in the system from freezing.
·If the cylinder is disassembled and not used for a long time, pay attention to surface rust prevention,the inlet and outlet ports should be added with dust-proof plugs and the piston rod and moving parts should be coated with anti-rust oil.

Installation and Use

1.Cylinder Fixation

1.1 Please refer to the table below to select the appropriate length of fixing screws and fix the cylinder according to the standard specified tightening torque. Too much tightening torque will cause poor action, too little tightening toque will cause position offset or parts falling of.

1.2 The cylinder can be fixed from three directions.

2. Jig Fixation

2.1 The jig can be installed on the front panel or top panel, which is convenient and flexible.

2.2 Please refer to the table below to select the appropriate length of jig fixing screws and fix the jig according to the tightening torque specified in the table.Generally, the length of the jig fixing screw should be shorter than the maximum tightening depth by more than 0.5mm to avoid hitting the guide rail and causing poor action.

2.3 When using linear guide rails as the support platform to fix the jig, please be careful not to apply strong impact force and excessive torque.2.4 When locking the jig to the slide table with bolts and others, please hold the slide table. Holding the body and locking it will apply excessive torque to the guide rail, causing a decrease in accuracy.

3.Hydraulic Shock Absorber Buffer3.1 The hydraulic shock absorber is a consumable item. When the energy absorption capacity decreases, it should be replaced in time. The table below is a comparison table of the hydraulic shock absorber models equipped with cylinders of various diameters.3.2 The screw hole at the end of the hydraulic shock absorber is not for adjustment.and random adjustment will cause oil leakage.3.3 Please use the tightening torque specified in the table below to tighten the hydraulic shock absorber lock nut.

4.Sensor Installation

4.1 All HLS series are magnetic, and the sensors are CMSH and DMSH series.For specific ordering methods and detailed parameters, please refer to the corresponding content.4.2 When installing the slide cylinder with the sensor, the minimum interval be tween the two adjacent cylinders must meet the requirements shown in the right figure.otherwise the sensor may sense poorly and produce misoperation.

5. Be sure to use the speed control valve and reduce the speed to below 500mm/s.

6. The actual lad and torque received by the cylinder must be within the check requirement range. Different types of torque acting on the cylinder will produce different degrees of displacement, and the specific displacement range refers to the table below.

6.1 Pitch torque changes the displacement of the slide table.

Within the full stroke range of the cylinder,the load acting on the arrow part will change the displacement of the side table (arrow part).

6.2 Swing torque changes the displacement of the slide table.

Within the full stroke range of the cylinder, the load acting on the arrow part will change the displacement of the slide table (arrow part).

7. Rolling torque changes the displacement of the slide table.

The load acting on part F will change the displacement of the slide table (part A).
