SC and SI cylinder cylinder and what is the difference between SU cylinder

Product features: SC cylinder lubrication free USES the oil-retaining bearing, the piston rod without lubrication. Terminal buffer except with a fixed buffer cylinder with adjustable cushion, make no impact on the smooth cylinder when reversing. Resistance to high temperature can use high temperature resistant seal material, make the normal work of the cylinder under the condition of high temperature in degrees Celsius ( Can be on-demand customization) for you SI: cylinder welding torch and the body insulation cylinder piston rod position is adjustable. But can prevent wound turn again. Cylinder piston rod head with Morse taper hole, make the welding torch installation more convenient. Welding torch compression strength, single cylinder is twice the size of the output force can ensure the quality of welding processing SU is lock cylinder
