Abstract: A single-sided fastener retaining device provides for low-profile, strong fastener retention, low FOD risk, compatibility with a wide range of driving tool and fastener types and sizes that is inexpensive to manufacture and capable of driving the fastener at an angle. A release mechanism includes a resilient arm and a lever arm joined by a fulcrum that contacts the shaft of a driving tool. A fork at the end of the lever arm includes first and second arms that extend to either side of and at least to the level of the axis of the driving tool to define an opening facing the axis to receive the shaft of a fastener of various sizes and hold the head of the fastener to the working end of the driving tool in a retained position. The release mechanism is responsive to the application of a force to elastically deform the resilient arm causing the lever arm to pivot on the fulcrum moving the fork away from the axis to a release position to release the fastener.

Abstract: A precision linear bearing is designed to minimize the points of contact, rolling and rubbing, to reduce particulates and FOD while ensuring stability and accuracy in a manner suitable for a clean room environment. The linear bearing comprises at least first and second bearing layers within a one-piece housing. Each bearing layer comprises at least three roller bearing spaced around the axial bore in a first plane within the housing, each roller bearing having an axis of rotation substantially perpendicular to the axial bore and projecting into said axial bore for engagement of a linear member extending through the axial bore. Each roller bearing suitably engages the linear member at a single point of contact. The layers are rotationally offset from one another such that the roller bearings contact different positions around the circumference of the linear member. The linear bearing may be configured to engage the inner surface of a cylindrical member.
