International Classification:

F16C029/06

US Classification:

384 43, 384 44

Abstract:

A linear motion bearing assembly () as provided for movement along a splined shaft (). The rolling element retainer of the bearing assembly () is assembled from a plurality of arcuate interengageable self-contained rolling element retainer segments (). Each of the rolling element retainer segments () includes at least one rolling element track () having a load bearing portion () and a return portion (). At least one load bearing plate () is axially positioned in each segment and serves to receive and transmit loads from the bearing rolling elements () in the load bearing portion () of the ball tracks (). An extended housing retainer structure encloses all of the exposed exterior surfaces of the rolling element retainer segments () and is configured and dimensioned to maintain the rolling element retainer segments () in position and to receive a load either directly or indirectly from the load bearing plates ().

Abstract:

A miter saw includes a tool adjustment unit having a joint pivotable about an axis, a guide rail spaced from and coupled to the joint so as to pivot about the axis, a saw housing mounted on the guide rail and a linear motion bearing assembly, which is positioned between the guide rail and the saw housing. The guide rail and the linear motion bearing are so shaped and dimensioned that the saw housing and the guide rail rotationally engage one another in a substantially play free manner to displace a saw blade between a plurality of angled positions.
