MECHANICAL COMPONENTSSprings, Gas Springs & DampersLocking gas spring simplifiesdesign of concealed elementsSpring shaftscan handlehigh speedsSKF has launched thelatest addition to itsStabilus LIFT-O-MATrange of gas springs.The LIFT-O-MAT PTLfeatures an internalmechanical lock in thecompressed position, openingup new opportunities for designerslooking for a simple way to createconcealed elements and storage areasinto furniture and specialised products,which can then be revealed quickly andeasily with just a light push.The innovative gas spring operates ina similar way to a ball point pen, lockingwhen compressed and disengaging toallow the spring to extend at a <strong>control</strong>ledContact springgives long lifeIn electronic devices, certaincomponents may require one or morespring contacts to achieve reliableelectrical connection. This is whereAbssac can help with its bespokeprecision electroformed products.Utilising a bellows spring contact, theelectrical connection can become a nonpermanent connection particularly whenthe parts are to be inserted, removed andre-inserted.The two types of spring contacts bestsuited for these applications are goldplatedwire mesh cylinders and goldplatedminiature metal bellows. Theseare available as standard stock items orcustom made to individual specification.Abssac’s Servometer bellows type contactsprings are manufactured from electrodeposited nickel, and then are goldplated to enhance their conductivity.They are both flexible and dynamic andare designed to provide a lifetime ofreliable interconnection.MORE INFORMATION:Enter G406 on the enquiry card, or visit ‘latest issuestories’ at www.industrialtechnology.co.uk forfurther details from Abssacrate when pushed. In addition to<strong>control</strong>ling the elevation of the objectreliably and smoothly, the gas spring alsofeatures an end position stop, eliminatingthe need for additional fixing elementsand minimising production andinstallation costs.As with the entire LIFT-O-MAT range,the PTL gas spring is able to offer a<strong>control</strong>led rate of elevation usinghydropneumatictechnology; as thepiston inside thecylinder moves from gasto oil, the spring slows to a dampenedpace, coming to a <strong>control</strong>led stop. Adynamic damping feature allows users tospecify the rate of elevation for aparticular application, making the LIFT-O-MAT an extremely flexible solution.Due to its combination of carefully<strong>control</strong>led elevation and innovativelocking functionality, the LIFT-O-MAT PTLis ideal for a diverse range ofapplications, including power towers inconference tables, back, arm andheadrest adjustments in sofas, andconcealed drinks cabinets in bar areas.MORE INFORMATION:Enter G405 on the enquiry card, or visit ‘latest issuestories’ at www.industrialtechnology.co.uk forfurther details from SKFVibration dampershandle 40,000N loadsLWA vibration damping units fromElesa feature natural rubberdamping pads built into anadjustable levelling foot design Theyhave been designed to damp vibrations,shocks and noise from movingcomponents or nonbalanced massessuch as rotating machinesThis vibration can damage operatorhealth as well as reducing the lifespanof the machine or adjacentequipment.Active machineisolation suits vibrationproducing equipmentsuch as presses,machine tools andtransfer equipment.Passive isolation suitsequipment that might beadversely affected by externalvibration, such as quality testing,measuring or performance assessmentequipment.The damping elements range from80mm to 200m in diameter withmaximum static load capacity of40,000N. They are made up of threemain elements: a zinc-plated steelbase with natural rubber disk, azinc-plated levelling disk, and athreaded stem to allow an easyand precise levelling of themachine.The vibration dampingelements are available indiameters of 80, 120, 160 and200mm.Documentationprovidestechnicalguidance on theselection toprovide the rightdamping/isolationlevel for thefrequency of vibration,static load andamplitude/deflection of the equipment.MORE INFORMATION:Enter G404 on the enquiry card, or visit ‘latestissue stories’ at www.industrialtechnology.co.ukfor further details from ElesaRino Industries has releasedflexible spring shafts thatare suitable for thetransmission of rotational <strong>motion</strong>They provide flexibility, strengthand endurance. They can operatecontinuously under high speedsand their shock-dampingproperties are excellent.There are a wide variety oftypical applications, these includeremote <strong>control</strong> instruments,transmission of rotationalmechanical power, shaftconnection and <strong>control</strong> ofoverhead parts. They can be usedin both left and right handrotations and it is advisable tochoose a left hand shaft to turnclockwise and a right hand shaftto turn counter-clockwise.Right hand shafts are availableas standard. The drive shafts areusually protected by a flexiblesteel sheathing and havecouplings on either end. They areavailable in lengths up to5000mm, but most are between500-1500mm.MORE INFORMATION:Enter G408 on the enquiry card, or visitwww.industrialtechnology.co.uk forfurther details from Rino IndustriesSaint-Gobainbuys Rencolfrom EriksSaint-Gobain PerformancePlastics has acquired RencolTolerance Rings, a UK-basedsubsidiary of Eriks, for £12.5million The arrangement includesthe company's activities in Bristoland Japan and a 51% <strong>control</strong>linginterest in Rencol MMI <strong>Technology</strong>in Singapore.
