1 Kerk onventiona s: FW Series Free Wheeing Kerk FW Series conventiona stye, without anti-backash function. The Kerk FW Series genera purpose free-wheeing nut is for appications not requiring anti-backash and wear compensation. It provides effective power transmission at minimum cost, and features ong ife, sef-ubricating poyaceta nuts. The secure mounting and convenience of a circuar fange is standard on the FW nuts with trianguar fange and thread mounting as an option. Many custom configurations are avaiabe. FW Series The FW is aso avaiabe in a Micro Series that enabes a whoe new range of micro-sized designs. It aows the miniaturization without sacrificing performance or reiabiity. Screws are 303 stainess stee with extended ife, custom Kerkote TFE coating optiona. ssembies can be suppied cut-to-ength or with ends machined to customer requirements.

10 Kerk onventiona s: Materia Options and TFE oatings Kerkite omposite Poymer s In addition to the Kerk sef-ubricating aceta nut materia, Haydon Kerk Motion Soutions offers a variety of custom compounded Kerkite composite poymers. Kerkite poymers are a famiy of high performance materias that offer exceptiona wear properties with the cost and design advantages afforded through injection moding. Kerkite poymers offer a variety of mechanica, therma and eectrica properties and are compatibe with many chemicas and environmenta conditions. Kerkite omposite Poymers are avaiabe options for most Kerk Lead-screw s and are standard materias for Linear Rai and Spine Shaft bushings, RGS arriages and Screwrai ushings and End Supports. Each member of the Kerkite famiy is compounded with ubricants, reinforcements and thermopastic poymers formuated to provide optimum performance in its target conditions and appications, resuting in superior performance and extended ife. cornerstone of the Haydon Kerk Motion Soutions advantage is design fexibiity. Kerkite omposite Poymers, aong with our injection moding and mod making capabiities, offer huge design advantages and cost savings compared with non-modabe materias. Kerkite high performance poymers outperform other pastics and outast meta bushings and bearings. When combined with Kerkote or ack Ice TFE coatings, Kerkite omposite Poymers have been shown to provide hundreds of miions of es of trave in customer appications whie continuing to maintain precise, accurate motion and positioning. Specia Materias In addition to the Kerk standard materia 303 stainess stee, sef ubricating aceta and Kerkite high performance composite poymers we aso work with a vast array of custom materias. Kerk has roed screws in many other materias, incuding 316 stainess, 400 series stainess, precipitate hardening materias, carbon stee, auminum, and titanium. Kerk nuts had been produced in many aternative pastics incuding PEEK, poyester, Toron, Vespe, PVDF, UHMW, Ertayte and customer-suppied speciaty materias. We have aso provided meta nuts made from bronze, brass, and stainess stee. With so much fexibiity in our manufacturing process, if the materia can be moded, machined, ground, or roed, Haydon Kerk Motion Soutions can ikey process it using state of the art machine toos, injection moding and mod making, grinding and thread roing equipment. Haydon Kerk Motion Soutions exces at suppying the best overa soution to meet our customers requirements. ontact Haydon Kerk Motion Soutions to find out how you can benefit from these choices. Kerkote TFE oating Kerkote TFE coating covering the entire screw surface resuts in an extremey even ubrication distribution. Test resuts indicate system torque requirements are consistenty ow with itte or no change in required frictiona driving torque, even with changes in motor R.P.M. Haydon Kerk Motion Soutions has deveoped a custom composition Kerkote TFE specificay for our ead screw and nut materias. It is appied using an automated process and provides extended nut ife and smooth operation with itte additiona cost. Kerkote TFE is a soft coating, a ong-term dry ubricant that is optimized for softer pastics ike acetas and nyons, with or without mechanica reinforcement. Lubrication to the nut/screw interface occurs by the nut picking up Kerkote TFE partices from the coating as we as from the migration of the interna ubricant within the pastic nut. though care is taken to ensure that chips and voids do not occur in the coating, sma voids have been shown to have no effect on system performance. The transfer of TFE to the nut continues throughout the operating ife of the assemby as ong as the nut periodicay traves over areas with Kerkote TFE coating. The ubricant, athough soid, aso has some spreading abiity as in fuid ubricants. Kerkote TFE coated screws provide the maximum eve of sef-ubrication and shoud not be additionay ubricated or used in environments where ois or other ubricant contamination is possibe. ack Ice TFE oating ack Ice TFE coating shares many of the benefits of Kerkote TFE but, in contrast, is a hard coating that offers exceptiona durabiity in a types of environments, with virtuay any type of poymer nut. ack Ice TFE coating remains on the screw, offering a ow friction surface upon which the nut traves. Rather than acting as a dry ubricant, ack Ice TFE is an anti-friction coating whose surface properties dispace the meta to which it is appied. Though it is not intended for use with meta or gass fiber reinforced nuts, ack Ice TFE is bonded securey to the screw s surface and can withstand abrasion from contamination, rigid poymer systems, fuid impingement and wash down appications. ack Ice TFE can be used in the presence of more aggressive environment conditions, or anywhere reduced friction and a permanent coating is desired. oth Kerkote and ack Ice TFE coatings offer the advantages of dry ubrication. These are maintenance-free coatings that are designed to ast the ife of the product. They are intended to be used without additiona ubricants, thereby further increasing the vaue of Kerk ead-screw assembies through eimination of the most common faiure of screw driven drives, ubrication faiure. There are certain appications where externa ubrication may be desired. These incude the use of nut materias such as gass reinforced pastic or meta. Greases, when used propery can provide unique capabiities and Haydon Kerk Motion Soutions does offer a seection of greases deveoped specificay for these appications. Pease contact a saes engineer for assistance seecting the best ubricant for your requirements. 10
