  • Publication number: 20050217449
    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.

  • Patent number: 6908228
    Abstract: A linear motion bearing assembly (20) as provided for movement along a splined shaft (10). The rolling element retainer of the bearing assembly (20) is assembled from a plurality of arcuate interengageable self-contained rolling element retainer segments (22). Each of the rolling element retainer segments (22) includes at least one rolling element track (30) having a load bearing portion (34) and a return portion (36). At least one load bearing plate (44) is axially positioned in each segment and serves to receive and transmit loads from the bearing rolling elements (32) in the load bearing portion (34) of the ball tracks (30). An extended housing retainer structure encloses all of the exposed exterior surfaces of the rolling element retainer segments (22) and is configured and dimensioned to maintain the rolling element retainer segments (22) in position and to receive a load either directly or indirectly from the load bearing plates (44).

  • Patent number: 5853248
    Abstract: A monolithically formed bearing is disclosed for use with a rotatable shaft positioned within a supporting structure which includes a bearing body having an internal bore extending partially therethrough and defining a cylindrical bearing surface for receiving and supporting the rotatable shaft, an external bearing surface having a radially inwardly tapered leading edge for engaging a complementary first abutment surface defined within an interior cavity of the supporting structure, an annular thrust collar projecting beyond the leading edge of the external bearing surface for engaging a corresponding second abutment surface defined within the interior cavity of the supporting structure, and an annular retention flange depending from the periphery of the bearing body to retain the bearing body within the interior cavity of the supporting structure.
