3、istration has authorized the use of this commercial item description for all federal agencies. 1. SCOPE. This commercial item description (CID) covers both “C“ (gap) and “4“ post frame type hydraulic bench- or pedestal-mounted, hand-operated, arbor presses of the standard commercial type, which are
4、used to force arbors into and out of holes or to assemble and disassemble press fit parts. 2. CLASSIFICATION. The arbor presses shall be classified by the following types and sizes: 2.1 Type. The arbor press shall be one of the following types, as specified (see (7.3(c): Type I - “C“ (gap) frame Typ
5、e II - “4“ post frame 2.2 Size. The arbor press shall be one of the following sizes, as specified (see (7.3(d): Size 10 - 10 ton Size 25 - 25 ton Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-51195B 2 3. SALIENT CHARACTERISTICS 3.1 Frame. The f
6、rame shall be of the “C“ (gap) or “4“ post frame type. When only one style of frame is acceptable, the particular style required shall be specified in the acquisition order (see 7.3(c). The frame shall support the hydraulic system and ram assembly. The frame shall provide a means for securing the pr
7、ess to a bench or pedestal. The ram shall be perpendicular to the table surface to an accuracy of 0.025 inch total indicator reading per 6 inches of ram travel. The table shall have an opening aligned with the ram axis that will allow passage of the arbor. 3.2 Hydraulic system. The hydraulic system
8、shall consist of a hand-operated pump, a fluid reservoir, a cylinder with ram, and the necessary fittings and hoses to ensure a complete hydraulic system. Unless otherwise specified in the acquisition order (see 7.3(e), the system shall be equipped with a single acting cylinder. The system shall hav
9、e overload protection and a means of preventing extension of the ram beyond its normal end-of-stroke position. Unless otherwise specified in the acquisition order (see 7.3(f), the stroke length of the ram shall be 10.125 inches. A pressure gauge calibrated to read tons of ram force shall be provided
10、. 3.3 Bolster plate. The “C“ (gap) frame presses shall be provided with a circular bolster plate having not less than four equally spaced slots of varying widths for the passage of an arbor. The bolster plate shall be removable and shall allow the desired plate slot to be positioned below the ram. 3
11、.4 Radius of work. The radius of work is defined as the distance from the center of the ram to the frame. Unless otherwise specified in the acquisition order (see 7.3(g), the radius of work for the press to be furnished shall be selected from table I. The tolerance of the radius of work shall be 0.5
12、 inch. TABLE I. Radius of work. Radius of work designation Radius of work (in) A 6.500 B 8.000 C 9.000 D 9.500 NOTE: Largest diameter of work is two times the radius. The radius of work designation is for use in developing the CID-based part or identification number only (see 7.1). 3.5 Vertical capa
13、city. The vertical capacity is defined as the distance when measured from top of table surface to ram (ram up). Unless otherwise specified in the acquisition order (see 7.3(h), the vertical capacity for the press to be furnished shall be as specified and selected from table II. The tolerance of the
