Abstract
A motion guide device includes a rolling passage formed between two members, a number of cylindrical roller bearing members disposed in the rolling passage and engaged between the members, and a number of spacers disposed in the rolling passage and engaged between the cylindrical roller bearing members, the spacers each include two opposite curved depressions for engaging with the cylindrical outer peripheral surfaces of the cylindrical roller bearing members, and each defined by a planar middle surface, a tilted upper surface and a tilted lower surface inclined relative to the planar middle surface and the vertical axis (Z) of the spacer for selectively engaging with the cylindrical roller bearing members.
Claims9
A motion guide device comprising:
- a first member and a second member including a rolling passage formed between said first and said second member,
- a plurality of cylindrical roller bearing members disposed in said rolling passage and engaged between said first and said second members for facilitating a movement between said first and said second members, said cylindrical roller bearing members each including a cylindrical outer peripheral surface and two end surfaces, and
- a plurality of spacers disposed in said rolling passage and engaged between said cylindrical roller bearing members for spacing said cylindrical roller bearing members from each other,
- wherein said spacers each include two opposite curved depressions formed therein for receiving and engaging with said cylindrical outer peripheral surfaces of said cylindrical roller bearing members respectively, and said depressions of said spacer are each formed and defined by a planar middle surface which is parallel to said vertical axis (Z) of said spacer, a tilted upper surface inclined relative to said planar middle surface and said vertical axis (Z) of said spacer for selectively engaging with said cylindrical outer peripheral surfaces of said cylindrical roller bearing members when said cylindrical roller bearing members are tilted relative to said spacer, and a tilted lower surface inclined relative to said planar middle surface and said vertical axis (Z) of said spacer for selectively engaging with said cylindrical outer peripheral surfaces of said cylindrical roller bearing members when said cylindrical roller bearing members are tilted relative to said spacer.
