Four-row linear recirculating ball bearing and guideway assemblies

with quad spacers or full complement

for quiet running

Quad spacers Full complement

for maximum load capacity

Dynamic characteristics, high load carrying capacity, little space requirement, small moving masses, low-maintenance or maintenance-free, high operational reliability. These are the demands now made on linear bearing arrangements and are fulfilled to a greater or lesser degree by the various guidance system concepts available. In many applications, however, a further central characteristic has been added to these: low-noise running . Low-noise guidance system Running noise in linear guidance systems can be reduced by various methods. Schaeffler has decided to adopt plastic spacer elements – so-called QUAD SPACERS. One quad spacer accommodates two rolling elements each from the compressive and tensile race- way. Since the balls are not in contact with each other, there is no collision noise. This reduces the noise in the recirculating system and the guidance systems run significantly more quietly. Since the quad spacers are not connected chain elements, bending and tensile stresses are eliminated, particularly in the return area. Under highly dynamic operating conditions or with ingress of contaminant particles into the guidance system, this design also averts the risk of fracture.With its new linear recirculating ball bearing and guideway assembly KUVE..-B-KT, Schaeffler is providing a technologically pioneering product for low-noise applications. This linear guidance system possesses all the advantages of the highly successful full complement KUVE design and represents an optimum addition to the already extensive range of these units. In this way, the INA range now includes the ideal product for any application.The KUVE..-B-KT is particularly suitable where the emphasis is on high dynamic characteristics and low noise.Both new carriage versions can be used on the existing guideways. Full complement guidance system The established and proven full complement KUVE series has been completely revised in technical terms. Due to the full complement concept, the KUVE..-B version has a high load carrying capacity. It is therefore used where the emphasis is on dynamic characteristics as well as maximum load carrying capacity and rigidity.
