A test apparatus is provided for measuring loads applied to an object and for measuring the deformation of the object in response to the loads. The test apparatus includes a stationary work head and a movable arm. The movable arm is selectively movable toward or away from the stationary work head. A load cell has a driven end mounted to the movable arm and a sensing end spaced from the movable arm. A movable work head is mounted to the sensing end and is configured for applying a load to a test object positioned between the stationary and movable work heads. A liner scale also is mounted to the sensing end of the load cell, and a linear encoder or read head is mounted in spaced relationship to the linear scale. The encoder reads deflection in the apparatus in view of loads applied during a test. A controller is provided for moving the movable work head in accordance with test parameters. The controller also receives output from the load cell and the read head, and uses that outputted information to develop stress-strain analytical data.

Test apparatus for measuring stresses and strains

A self-lubricating bearing assembly for supporting a load on a guide rail which includes a carriage having first and second ends, a guide surface adapter for translation atop the guide rail and an end cap assembly which mounts adjacent one of the ends of the carriage. The end cap assembly includes a seal and a lubricating assembly having a lubricating block made from a lubricant composition and a compression housing for enclosing a periphery of the lubricating block and for biasing the lubricating block against the guide rail to cause the lubricant to contact the rail.
