Electric linear cylinders are a type of linear actuator that convert electrical energy into linear motion
Electric linear cylinders are a
type of linear actuator that convert electrical energy into linear motion. They
are widely used in various industries, including automotive, aerospace,
medical, and manufacturing, to move or position loads with high precision and
control.
Electric linear cylinders consist
of a motor, a gearbox, a screw or a belt, and a carriage that moves along the
screw or the belt. The motor provides the rotational energy, which is
transmitted to the gearbox that reduces the speed and increases the torque. The
screw or the belt converts the rotary motion of the gearbox into linear motion,
and the carriage carries the load. Global
electric linear cylinders market was valued at US$ 595.7 Mn in 2018 and
is expected to reach US$ 962.5 Mn in
2027, exhibiting a CAGR of 5.5%
over the forecast period (2019–2027)
A recent trend in the industry is
technological breakthroughs in the design and development of electric linear
cylinders and actuators. Pneumatic and hydraulic cylinders are high-performance
and expensive alternatives to electric cylinders, which has prompted
manufacturers to concentrate on design innovation and enhance the capabilities
of electric linear cylinders. For instance, Bosch Rexroth provides customised
advanced control technology that enables adjustments to the position, force,
and travel speed characteristics.
High energy efficiency, compact
structural design, high performance electromechanical cylinders with
high-precision ball screw assemblies, complete turn-key systems, and sanitary
design are all provided by the firm for customers. The current emphasis of
major manufacturers is on delivering an electric linear cylinder with a small,
strong, and dependable design that has a longer lifespan and requires little
maintenance.
There are two main types of electric
linear cylinders: ball screw and belt-driven. Ball screw electric
linear cylinders use a screw with recirculating ball bearings that roll along
the screw's grooves, reducing friction and increasing efficiency. Belt-driven
electric linear cylinders use a toothed belt that moves along pulleys,
providing high-speed and quiet operation.
One of the main advantages of
electric linear cylinders is their high precision and repeatability. They can
achieve accuracies of up to 0.01 mm and repeatability of up to 0.005 mm, making
them suitable for applications that require high positional accuracy, such as
pick-and-place systems, robotic arms, and CNC machines.
