When smooth linear motion is of paramount importance
For applications where reductions in weight are paramount , IKO offers the cost-effective precision linear slide range . Made from stainless steel , and available in recirculating ( BSR ) and nonrecirculating ( BSP ) options , this range is highly flexible . It features a simple tworow , four-point contact structure , high motion accuracy and stable load carrying capacity .
This can be further enhanced using a built-in rack and pinion system in the BSP variant ( BSPG ) for applications where there is potential for cage creep . This phenomenon is generally seen in many vertically orientated , high-speed applications , and IKO ’ s design reduces the chance of this occurring .
For applications that may receive fluctuating and complex loads , but still need to see consistent repeatable results , the BWU range may be more appropriate . The high rigidity , precision linear slide units offer design engineers the possibility of adding a secure mounting position that can handle loads of up to 12,100N . They are also exclusively made of stainless steel , making them suitable for potentially corrosive environments or cleanrooms . In addition , they are suitable for applications where rust prevention oil is not preferred .

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 three different variants , including a rack and pinion option ( CRWG ) and a heavierduty variant that increases the strength of the internal components ( CRWH ). 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 .
Despite the variation in materials and structure , all of the models share a similar design . With single linear caged bearings consisting of ball or roller elements running along inner and outer tracks . These bearings are arranged in parallel , one on each side of the slide , to support the weight of the table ( or carriage ) and its mounted load as it moves .
The various designs all 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 the raceways seen in recirculating designs ,
there is no chance of the balls causing any background distortions in the data gathered . For the same reason , the bearings run very quietly . In addition , maximum speeds of 50m / min can be achieved .
While IKO prizes quality over pricing , one thing for customers to keep in mind when buying precision linear ways is how many parts are included . This is particularly important when specifying the CRW range . While , for historical reasons , many competitors sell these parts in what is essentially only half of a full set required for any motion profile – two ways with one cage and rolling elements – IKO always sells CRWs as a complete kit : four ways with two cages and rolling elements . For that reason , a price that is perhaps 75 % higher for an IKO full set ( for example ) when compared to a competitor ’ s set might prove to be a more cost-effective option , as two sets of the competitor ’ s product would be needed to make up the same quantity as IKO ’ s offering .
By offering the right bearings in an installation-friendly manner , IKO aims to meet its customers ’ needs – and often exceeds them .
