Adjustable chocks allow easy mounting of rotating equipment

SKF has developed a new range of adjustable chocks with higher load capacity and an increased adjustment range. The chocks can be used in many industries, including food and beverage, pulp and paper, rail, marine, offshore, agriculture and power generation. They are typically found in equipment such as gas, diesel and LNG engines, generators, compressors, electric motors and gearboxes.

The Vibracon E series – which includes four different models – features improved self-levelling and height adjustment. The chocks allow all types of rotating equipment to be mounted easily and accurately to base frames and either steel or concrete foundations. “They help to simplify the installation of rotating machinery, which improves technical and economic performance,” says Rene Vermeulen, senior engineering sales manager at SKF.

The chocks accommodate angular differences of up to 4° between machine and mounting base – without having to machine the base or install epoxy resin chocks. This self-levelling ability, combined with height adjustment, reduces the possibility of a soft foot in the production line. The chocks can also lower the cost of equipment foundations – whether designed-in or retrofitted

The four products in the Vibracon E range are: carbon steel chocks; surface treated chocks; stainless steel chocks; and low-profile elements.

Carbon steel chocks are suitable for indoor applications, such as on the factory floor. Surface-treated products are for more extreme environments such as humid or salty climates. Stainless steel variants are aimed at the most demanding conditions, such as in the oil and gas industry. Low-profile elements offer an economic alternative to more expensive milled chocks, shims, or epoxy resins.

A broad range of specialist adjustment tools – available from SKF – allows technicians to alter chock height with maximum safety and comfort. In addition, the chocks are backed by SKF’s expertise in maintenance and shaft alignment.
