A linear ball bearing having a guide carriage () which is guided on a guide rail () in a longitudinally displaceable manner and is mounted in rolling contact on longitudinal sides of the guide rail () via balls () which are arranged on each longitudinal side in at least two parallel ball rows () encircling in endless ball channels (), each ball () of the one ball row () together with an adjacent ball () of the other ball row () being held all round in cage pockets () of a common cage piece (), the cage piece () having exactly two cage pockets () for one ball () each from both ball rows (), each cage piece (), as viewed in the running direction of the balls (), being provided at both ends with convexly curved end surfaces () for contact with the end surfaces () of adjacent cage pieces (), which end surfaces () extend essentially up to the cage piece sides ().

Linear ball bearing

In a linear rolling bearing comprising a guide rail () and a guide carriage () that partially surrounds the guide rail () and is supported for sliding through rolling elements () on two long sides of the guide rail (), the rolling elements () being arranged on each of the two long sides in at least two parallel, endlessly re-circulating rows () of rolling elements () while a spacer () is inserted between every two successive rolling elements () of a row (), on each long side of the guide rail (), a common spacer () for both rows () is inserted between every two adjacent rolling elements () of the one row () and between every two adjacent rolling elements () of the other row ().

Linear rolling bearing

A linear guide unit comprising a guide carriage () that is mounted through rolling elements () for sliding on a guide rail (), said guide carriage () comprising a carrier body () and end caps () arranged on front ends of the carrier body (), the linear guide unit comprising at least one endless rolling element channel () comprising a load-bearing channel () for load-bearing rolling elements (), a return channel () for returning rolling elements () and two deflecting channels () that connect the load-bearing channel () and the return channel () endlessly to each other and are defined by the end caps (), a support rail () arranged along the load-bearing channel () and supported on the carrier body () comprising a raceway () for the rolling elements () that defines the load-bearing channel () the support rail () comprising a support member () and a saddle member (), the support member () being received on the carrier body (), and the saddle member () comprising the raceway () while being supported through a saddle surface () for tilting motion on the support member ().

Linear guiding unit

Linear rolling bearing with longitudinal sealing elements

A guide rail arrangement for connecting two relatively displaceable components comprising a lower rail (1) and an upper rail (2) supported thereon by rolling elements (3), said lower and upper rails being configured as rectilinear sheet metal profiles, one of the lower and upper rails partially surrounding the other of the lower and upper rails, whereby hollow spaces are formed for receiving the rolling elements (3) and further slide elements (4) arranged between the rails is characterized in that, in a central region of the arrangement, the two rails (1, 2) define a receiving space (5) for a spring and/or damping element, which receiving space (5) is adjoined by regions comprising the rolling elements and the slide elements (4) and extending in end regions of the rails (1, 2) which results in the creation of an arrangement with uniform load distribution on its components so that a deformation of the components and a pressing-in of the rolling elements is reliably prevented.
