BECA (1) Natural frequency : 8 to 14 Hz DESCRIPTION The BECA mounting comprises one piece elastomer bonded to a top and bottom plate. Top plate: smooth or threaded (welded nut) hole. Bottom plate: Fixing lugs or direct bearing on the ground. Bonded rubber. Domed rubber ring. Anti-slip bead or grooved anti-slip sole. Removable protective top cover : protects the rubber and distributes the load. OPERATION The design of the BECA mounting gives the following basic characteristics : Transverse elasticity approximately the same as the axial elasticity (equi-frequency). Rubber works in compression. Progressive buffer against shocks or accidental overload. Anti-slip (may be placed directly on the ground). Advantages : The machine may be placed (with its mountings) directly on the ground. Very slim. Speed of fixing. Simple removal of the assembly. Extensive range: 3 hardnesses of rubber for 6 existing sizes, allowing the mounting to be optimised as a function of the load and stimulation frequency. A choice of 3 fixing styles. Recommendations : In order not to affect the suspension of the machine, all external connections must be flexible. BECA mountings can be used for fixed, well-balanced rotating machinery, otherwise a ballasting slab should be used. (1) Natural frequencies with max/min loads, see : OPERATING CHARACTERISTICS. Nota : BECA mountings can be replaced by PAULSTRADYN mountings. 72DIMENSIONS Section XX Section XX Section XX A A C1 C C M D M F XX X X X X Fig. a Fig. b Fig. c BECA with anti-slip base BECA with lugs, smooth hole BECA with lugs, threaded hole Reference A B B C D E F J M Weight 1 Anti-slip base Diamond base Type Hardness C mm mm mm mm mm mm mm mm mm g 1 Smooth Smooth Threaded hole (fig. a) hole (fig. b) hole (fig. c) -- -- 533641* 40 20 18 - M6 52 6.2 64 2 19 50 40 45.60 -- -- 533661 60 24 22.5 - M6 76 6.2 90 2 18 140 60 45.60.75 -- 533581 533681 80 27 25 8.1 M8 100 8.2 120 2 22 250 80 45.60.75 533108 -- -- 100 30 28 10.2 - - - - - 22 420 100 45.60.75 -- 533109 533609 100 27.5 25.5 10.2 M10 124 10.2 148 2.5 22 460 100 45.60.75 533151 -- -- 150 41 38 14.2 - - - - - 34 1220 150 45.60.75 -- 533152 533652 150 39 36 14.2 M14 182 12.2 214 4 34 1340 150 45.60.75 533202 -- -- 200 46 42 18 - - - - - 44 2750 200 45.60.75 -- 533203 533623 200 44 40 18 M18 240 14.5 280 5 44 3030 200 45.60.75 * 40, M6 - RAPID nut - max. torque 3 N.m.
