Cylinder types
Single-acting displacement cylinders were among the first cylinders that Motus made way back in the 1960’s for Hustler’s forklift masts.
A unique gland design allowed for spear and bore combinations to be similar in diameter to maximise strength to withstand long extention lengths and side-load which is a common issue with lifting cylinders sometimes required to be several metres long and fitted in restricted spaces.
Motus have 3 main types of single-acting cylinders: the wire retained clip method, a guide piston and a solid body design for maximum strength and endurance.
Displacement Cylinders Displacement cylinders have no piston. The effective diameter is the shaft diameter, so a 2” displacement cylinder has the same power as a 2”x 1” double-acting cylinder.
A displacement cylinder requires no breather, has head seals only and is typically used on simple designs: forklift cylinder, truck/ute deck tilt, post driver cylinders, or older front-end loader lift cylinders.
Spacers Some longer stroke cylinders (especially if horizontal) will require a spacer between head and piston, i.e. 21/2 x 11/2 x 900mm horizontal may require a 100mm long spacer.
