Patent ID: 8764294

Claim:
A recirculating element guide for rolling elements for use in a linear guide unit having a carriage part; and a rail part, the recirculating element guide comprising: two loaded rolling element rows and two unloaded rolling element rows, a bearing cage for the rolling elements which at least partially guides both the two loaded rolling element rows and the two unloaded rolling element rows, the bearing cage comprising a plurality of bearing cage components including a first bearing cage component and a second bearing cage component, the second bearing cage component comprising a central part in the area of a center line of the bearing cage, the first bearing cage component and the central part forming a guide channel therebetween for loaded rolling elements of the two loaded rolling element rows, an elongate plate component secured on the bearing cage, the elongate plate component having two rolling element raceways corresponding to the two loaded rolling element rows, and two discrete contact surfaces disposed opposite the two rolling element raceways, and configured to contact respective contact surfaces on the carriage part of the linear guide unit to absorb the compressive forces acting between the elongate plate and the carriage part, wherein the first bearing cage component has two first guide grooves and the second bearing cage component has two second guide grooves, the first guide grooves and the second guide grooves complement each other to form two tubular guide channels therebetween respectively holding the two unloaded rolling element rows, and two confrontingly opposed sealing lips arranged on the first bearing cage component for contact with the rail part and disposed in a volume defined between the two tubular guide channels.
