An apparatus is provided that includes a diamond bearing surface positioned in sliding engagement with an opposing bearing surface of a diamond reactive material. The opposing bearing surface is hardened via a material treatment.

A braking system for a gear box assembly is provided. In one example, braking system comprises a double disk brake configuration arranged in a gear housing. A working position of the double disk brake is configured to automatically adjust based on a condition of a friction pad of a friction disk.

Output lever (11) with cam follower rollers, where the lever has two follower rollers (24A, 24B) connected to a body (110). The body defines a median plane (P11) which has a central portion (116), with two opposing surfaces (117A, 117B), and two attachment portions (122A, 122B), each connected, by means of a respective attachment device (28), to a respective follower roller. Each attachment device has an inner fastener (28A) and an outer fastener (28B), each of which has one or more flanges (30, 32, 34; 30, 32, 34, 70). The flanges are each formed in a plate and bear bears in parallel planes against each other. Each follower roller is clevis-mounted between the inner and outer fastener so that contact surfaces (S242) of the two follower rollers are located on either side of the median plane.

A cam follower assembly for a can bodymaker includes a slider structured to be coupled to the proximal end of a ram body of the can bodymaker; and a plurality of cam follower members rotatably coupled to the slider. The cam follower members are structured to be operatively coupled to a cam of a ram drive assembly.

A roller tappet for a fuel pump is provided that has a guide housing which includes a drive-side and output-side section of the same external diameter, and a separate support body extending longitudinally through the guide housing. An upper face on the drive-side section carries a pin with a roller thereon. A lower face of the output-side section interacts at least indirectly with an arrangement for a pump piston. The drive-side section and the output-side section are axially spaced rings connected to one another via the support body. The support body has a first ring area with the upper face and a second ring area with the lower face. The first ring area is connected to an inner jacket of the drive-side section and the second ring area is connected to an inner jacket of the output-side section.

A buffered cam assembly, which is particularly well-suited for use to provide a clock input for a mechanical computing system, interposes a buffer element between a cam surface and a follower. The buffer element engages the cam surface and acts to significantly reduce the effect of any irregularities in the cam surface on the resulting motion of the follower, allowing the output waveform of movement of the follower to more closely approximate an intended ideal output waveform.
