This is where IKO Nippon Thompson ’ s in-house design and adjustments service becomes invaluable , with the UK team of applications engineers able to suggest design

Mark Ross , technical sales engineer at the company ’ s Milton Keynes UK headquarters , says : “ There are a wide range of things we can do at local level , from the everyday to the more unusual , to deliver an application-specific solution , providing a key service that can save UK customers time

For designers and machine builders looking to increase load ratings further , while keeping the overall machine size to a minimum , IKO can then offer its crossed roller ways ( CRW ). This range is available in requirements three different .” variants , including a rack and pinion option ( CRWG ) and a heavier-duty variant that increases the strength of the internal components ( CRWH ).
Mark explains .
These products all utilise cylindrical rolling elements instead of ball bearings , and provide increased load rating capacity and improved rigidity . This , in turn , increases the stability of the overall product .
Mark . “ From there we have the in-house capabilities to modify standard products to meet specific customer
Examples include cutting rail to specific length at the simplest level , or changing the e-dimension – the measure from the end of the rail to the first mounting hole . “ As standard , this e-dimension would be half the normal hole pitch , but that might not suit the application ,”
Such adjustments and amendments can be important time savers for customers , particularly when they are building a prototype as proof of concept . But IKO Nippon Thompson ’ s design services can also save customers significant amounts of money , for example when it is clear that the design engineer has over-specified the project , perhaps as a belt and braces approach to meeting particular lifespan requirements .
“ We can quickly drill down to the customer ’ s most important considerations and then look at how that impacts

on the rail and carriage dimensions ,” says Mark . “ By talking through load and stroke requirements , that might lead us to propose alternative carriage lengths . For example , has the designer opted for a shorter carriage to increase
The various designs all
INDUSTRIAL TECHNOLOGY • WWW . INDUSTRIALTECHNOLOGY . CO . UK provide precise accurate motion , normally over short stroke lengths . In the BSP , BWU and CRW ranges , this motion is further enhanced by their non-recirculating design . Due to the compression and release of the rolling elements as they pass in and out of contact with stroke length , but then bumped up the rail and carriage dimensions to accommodate the required load ? Perhaps they ’ ve even ended up with a design that uses non-standard length carriages . “ By adjusting the rail and carriage dimen- the raceways seen in recirculating
