What Type of Lubricants do the Actuators Use ?
The EM (TracMaster) and EMA series actuators are grease lubricated for the ram and gearbox assemblies. The Rolaram actuators typically have a grease lubricated ram and oil lubricated gearbox, however this is reviewed for high duty applications where a totally oil lubricated unit may be required. The EMA and Rolaram units can both be supplied with industry specific lubricants, such as food or nuclear grade grease.
The standard screw jacks are grease (EP2) lubricated for the lifting screw and gearbox assemblies. The high duty “Sym-metric” screw jack is oil lubricated for the gearbox and grease (EP2) lubricated for the lifting screw. All screw jacks can be supplied with industry specific lubricants, such as food or nuclear grade grease.
… For ball screw jacks the lifting screw cannot be keyed, as the keyway would interrupt the ball track, permitting loss of the recirculating balls. http://www.powerjacks.com/Screw-Jacks-FAQ.htm Power Jacks Group market leading manufacturer of screw jacks, Power Jacks Group market leader for screw jacks, electric linear actuators, bevel gearboxes, roller screws, mechanical jacks, winches and complete linear motion systems. … Metric Machine Screw Jacks, http://www.powerjacks.com/ Nook Industries – Providing Ball Screws, Lead Screws, Acme Screws and … Nook Industries provides a complete selection of Ball Screws, Acme Screws, Lead Screws, ActionJac Worm Gear Screw Jacks, Linear shafting and 60 case shafting. http://www.mechanicalactuators.com/info/ProductsHome.cfm Jack Screws, Screw Jack Nook ActionJac Worm Gear Screw Jacks are mechanical actuators that utilize a bronze worm gear with a screw. … INCH BALL AND MACHINE SCREW JACKS http://www.nookindustries.com/jack/JackHome.cfm FESTO
