1 The economical machinery mounting solutionSKF VibraconWhy use SKF Vibracon ? SKF Vibracon is a self leveling, height adjustable and re-usable chock. Easy and accurate mounting of all types of rotating equipment to base frames, steel foundations or concrete. Eliminates soft foot. Reduces the cost of equipment foundations by design for the first build or through retrofit. SKF Vibracon has many well documented applications and references. Wide choice of standard Vibracon can help save costs in: Industrial and energy applications Marine and offshore applications Military and navy applicationsSKF Vibracon is typically used for: Gas and diesel engines Compressors Electric motors Gearboxes Generators Pumps and fans Bearing housings Turbines Other critical rotating machinerySKF Vibracon chocks have been rigorously tested both in the laboratory and the field, in all types of environments and applications under the scrutiny of designers, production managers, OEM commissioning engineers, operators and owners.

Mating surfaces are treated with additives to avoid seizing of the parts when rotated. Carbon steel chocks (-CS)The SKF Vibracon adjustable chock has many configurations and material options to satisfy technical concerns, the carbon steel models being suitable for indoor use. Additives are added to the mating surfaces providing initial protection before and during installation and avoid seizing of the parts when rotated. The products provide an economic solution for environmentally less demanding applications, while guaranteeing a lifetime reliable chocking.

4 Surface treated chocks (-CSTR) Many installations where the SKF Vibracon chocks are applied can be found in tough, humid and salty climates, where protection against corrosion is recommended. To cater for this need, SKF has been testing different solutions resulting in the surface treated SKF Vibracon chock. All parts are treated individually to guarantee an optimal result, consistent quality and extended corrosion protecting capabilities. 1) Minimum reduced height can be reached by machining the centre and bottom part of the SKF Vibracon chock on a Vibracon low profileSKF Vibracon3MA DesignationBolt sizeTightening torque 1)Bolt sizeTightening torque 1)Max. bolt size 2)Machine load 3)Proof load 4)MetricNmMetricNmMetrickNkNSM 12 -CSSM 12 -CSTRSM 12 -SSM1285M14110M168160SM 16 -CSSM 16 -CSTRSM 16 -SSM16215M18270M2015175SM 20 -CSSM 20 -CSTRSM 20 -SSM20420M22500M2425250SM 24 -CSSM 24 -CSTRSM 24 -SSM24730M27890M3035420SM 30 -CSSM 30 -CSTRSM 30 -SSM301 460M331 745M3660600SM 36 -CSSM 36 -CSTRSM 36 -SSM362 570M393 000M4290775SM 42 -CSSM 42 -CSTRSM 42 -SSM424 125M454 995M48120 1 275SM 48 -CSSM 48 -CSTRSM 48 -SSM486 210M527 175M56160 1 300SM 56 -CSSM 56 -CSTRSM 56 -SSM5610 035M6010 360M64225 1 750SM 64 -CSSM 64 -CSTRSM 64 -SSM6415 165M6816 320M72300 1 900 SKF Vibracon low profileSM 16 LP-ASTRM16215M18270M2015255SM 20 LP-ASTRM20420M22500M2425270SM 24 LP-ASTRM24730M27890M3035310SM 30 LP-ASTRM301 460M331 745M3660475SM 36 LP-ASTRM362 570M393 000M42901 000SM 42

SKF Vibracon low profile configuration addresses those applications where the chock height between the foundation and component has been established by the previous design. Most of the other chocking methods are time-consuming and do not support the life cycle needs of the machine owners and installation activities on a tight schedule. How to select the appropriate SKF Vibracon chock1) Torque values are valid for bolts with metric thread, material grade , yield strength >640 N/mm2, oil lubricated thread courses and nut mating surfaces without slide additives.

6 2) Optional bolt size . For an engineered solution, please contact Machine load is the sum of the weight of the component and the dynamic forces on the SKF Vibracon for the heaviest loaded position, multiplied by a safety ) Proof load is the tested load which can be applied on the SKF Vibracon chock at maximum height before plastic deformation will occur. Exceeding the proof load will permanently deform the element, rendering it no longer adjustable. This is a tested load for SKF Vibracon surface treated chocks only.
