This disclosure relates to a wear button or pad for a telescoping boom of the type comprising at least an outer boom member comprising a threaded bore therethrough for the wear pad assembly, and an inner boom member that is slidable with respect to the outer boom member. In one form, the wear pad assembly comprises a wear pad and a base, a first of which comprises a generally cylindrical body comprising a curved external side surface comprising a screw thread via which this is threadably engageable in the threaded bore, and an internally tapered expandable collet, and the second of which comprises an externally and complementarily tapered mandrel portion, wherein in use, the externally threaded part is threadably engaged in the threaded bore and expanded therein by insertion of the externally and complementarily tapered mandrel portion in the expandable collet.

A sliding linear bearing includes a guide shaft on which a slider is movably guided in a guide direction. Bushes are inserted between the guide shaft and the slider including a main bush that is fixedly attached to the slider and a preloading bush that is held so as to be rotatable relative to the slider about the guide direction while being preloaded with a torque. The main bush and the preloading bush are preloaded by the torque in opposite directions of rotation without play relative to the guide shaft. A contact region between each of the bushes and the guide shaft blocks rotation about the guide direction between the slider and the guide shaft in both directions of rotation.

A linear guide mechanism includes an actuator side guide member, moving block side guide members disposed on both sides of the actuator side guide member, and a plurality of balls disposed in two rows, respectively, between the actuator side guide member and each of the moving block side guide members. Set screws that are capable of adjusting a pre-loading of the balls and are capable of improving the straightness of the moving block side guide members, are attached to a moving block.

The present invention relates to a guide device for a machine tool comprising a base body having at least one contact surface, a guide rail having at least one bearing surface and a guide axis, and a plurality of exchangeable support plates for positioning the guide rail on the base body.

A slider assembly (10) for a transportation system (100) for transporting an object (101) is provided. The slider assembly (10) comprises a first support (12a) and a second support (12b), a first guiding element (14a) arranged on the first support (12a) and a second guiding element (14b) arranged on the second support (12b), wherein the first guiding element (14a) is configured to receive a first rail (104a) and the second guiding element (14b) is configured to receive a second rail (104b), such that the slider assembly (10) is slidably arrangeable on the first rail (104a) and the second rail (104b). The slider assembly further comprises a tolerance compensation element (18), which connects the first support (12a) and the second support (12b), such that at least a part of the first support (12a) and at least a part of the second support (12b) are spaced apart from each other, thereby allowing a relative movement of the first support (12a) and the second support (12b) with respect to each other.

In order to provide a guide device which is of simple construction and allows a stable and haptically pleasing sliding function, it is proposed that the guide device comprise the following: a first guide rail; a second guide rail; a bearing device by means of which the first guide rail and the second guide rail are mounted movably relative to each other; a coupling device that is different from the bearing device for influencing a movement of the guide rails relative to each other.

A linear guide mechanism includes an actuator side guide member, moving block side guide members disposed on both sides of the actuator side guide member, and a plurality of balls disposed in two rows, respectively, between the actuator side guide member and each of the moving block side guide members. Set screws are attached to a moving block.

A telescopic side arm for a refuse vehicle has an inner and outer boom. A mounting assembly secures the outer boom with a refuse vehicle. A plurality of bearing pads is positioned between the inner and outer booms to provide smooth movement between the inner and outer booms. A plurality of shims is associated with the bearing pads to assure a tight fit between the inner and outer booms.
