Linear Actuators are Lubed for Life

Linear Actuators are Lubed for Life Featuring a compact design with the drive motor mounted alongside the actuator mechanism, the new Jaeger IMD3 linear actuators from SKF combine enhanced corrosion resistance with lifetime lubrication. As standard, the units offer IP53 ingress protection, and versions with IP65 protection can also be supplied. The new actuators are, therefore, an ideal choice for applications such as ice-cream dispensers, commercial lawn mowers and salt-spray systems, as well as for use in healthcare equipment, where maintenance requirements must be minimised, even though the actuators are likely to be exposed to liquids and potential sources of corrosion. Available in versions for operation from 12, 24 and 36V DC supplies, IMD3 actuators have aluminium outer and extension inner tubes, with the drive motor and gears protected by a robust zinc-alloy housing. Precision-manufactured sintered gears ensure low operating noise and high efficiency. The IMD3 compact actuator range includes four models. The IMD3 5 develops an operating force of 120N, and the corresponding figures for the other models are 240N for the IMD3 10, 500N for the IMD3 20 and 750N for the IMD3 30. In every case, the forces are the same whether the actuators are pushing or pulling. Maximum operating speeds under full load conditions range from 45mm/s for the IMD3 5 to 8mm/s for the IMD3 30. All models are offered with a choice of six stroke lengths from 50mm to 300mm, and all except the IMD3 20 and IMD3 30 can be factory fitted with an integral potentiometer to provide positional feedback. IMD3 actuators are compatible with Jaeger CB200 control boxes for single actuators and two actuators connected in parallel, CB300 control boxes which can provide independent control for two actuators, and CB800 control boxes which can provide independent control for four actuators. The control boxes are complemented by a range of handheld operating units.
