14Modular Pneumatic Linear Drives OSP-LSupport bearingsInserting the magnet strips (see diagram)Note:With cylinders from Ø 40, the magnet strips can slip out of the cylinder profile. Insert these into the cylinderprofile as follows:• Push one magnet strip in, leaving 5 cm sticking out (it must lie on itssmall side) – or, if it had remained in the cylinder profile, pull it outa little.• Place the second magnet strip on its narrow side above the first magnetstrip:If the magnets repel each other:• Push in the second magnet strip without turning it over (see diagramm).If the magnets attract each other:• Turn the second magnet strip over i.e. 180° (about its longitudinal axis)and then push it in.Prepare piston for installation• Insert both slide shoes (28) into piston yoke. Colour same as old parts, because same dimensions.• Select the two support rings (25) (colour same as old parts),• Insert the steel bolt (29) and aluminum bolt (41) separated by the magnet (30) into a support ring.See Section 14 for the positioning of the parts.• Push the two support rings on to piston (so that flat band guides are on top - see diagram).• Clip both support rings together, taking care to ensure that the steel bolt,aluminum bolt and magnet remain in the correct position.Check that piston moves smoothly, as follows:• Insert piston into cylinder bore (1) and slide it up and down.• Replace slide shoe and/or support ring if:- piston is too tight, or- piston has too much play.• Take piston out again.• For the tandem version, only mount cushioning seals (23) onthe respective outer sides of both pistons.• Insert cushioning seals (23) (so that seal lip shows on outside).Greasing cylinder bore• Grease inside of cylinder bore as far as you can reach, grease insidesurface with original grease only (see spare parts page 23 -1ubrication).• Grease the two support rings and piston behind support rings.• Slide piston up and down a few times (long cylinders, however, should be greased right through).• Take piston out again.• Check that cylinder bore has a complete grease film, as follows:- Point cylinder at a light source and look through it, no dry spot must be left.- Repeat greasing process if required.Insert the inner sealing band:• Insert the inner sealing band (17) into the cylinder (slot pointing upward) with the flat side pointingdown (do not press into the slot).• The inner sealing band (17) should protrude approx. one piston length out of one side of the cylinderbarrel.Cylinder barrel
