QGB series bounce cylinder

QGB50×180-CA

QGB series cylinder is a bounce cylinder. The working medium is compressed air with oil mist that has been conducted with purification treatment.
The cushioning function of the cylinder is as follows: when the piston moves to the end of the stroke, the cushioning device installed inside the cylinder begins to take effect, which will reduce the moving speed of piston, make the piston move stably and avoid shock. The series of cylinders with the diameters of φ40 and φ50mm are of non-adjustable cushioning, and the series of cylinders with the diameters of φ63mm and above are of adjustable cushioning.

Note QGA①-②-③
①Inner diameter of cylinder ②Stroke of cylinder ③Installation method of cylinder without mark: fundamental type f: front flange type F: rear flange type G: foot type B: medium pivoted axle S: suspension type in the rear part

Inner diameter of cylinder（mm)	Stroke range(mm)	Scope of working pressure(MPa)	Ambient medium temperature（℃）	Theoretic acting force(N) ( calculated when the pressure is 0.4MPa)
Inner diameter of cylinder（mm)	Stroke range(mm)	Scope of working pressure(MPa)	Ambient medium temperature（℃）	Thrust	Tensile force
φ40	40～300	0.15～0.8	-10～80	500	450
φ50	40～300	0.15～0.8		780	700
φ63	63～800	0.15～0.8		1250	1120
φ80	63～800	0.15～0.8		2010	1880
φ100	100～1500	0.15～0.8		3140	2940

φ250	250～2500	0.1～0.8		19640	18860
φ320	300～2500	0.1～0.8		32160	30910
φ400	300～2500	0.1～0.8		50400	48400

Note: When choosing cylinders according to the above table, increase the theoretic thrust and tensile force by 15~20%.
