Zhejiang Dongrun Casting Industry Co,.Ltd supply the most comprehensive range of bellhousings in China meeting all worldwide standards such as VDMA, NEMA and ATEX.
Bell housings are the mechanical elements used to connect an electric motor equipped with standard flange to a hydraulic pump, thus forming the pump/motor unit. The bell housings of this range allow to establish a perfect assembly between electrical motors with standard flange up to 270 kW and the majority of the hydraulic pumps available on the world market.
They are produced in aluminium alloy and are divided into two categories:
Single piece bell housings
Composite Bell housings
Base Bell housing + flange
Base Bell housing + distance ring + flange
Materials and Material Properties:
Bell housings: Aluminium alloy for die casting process and sand casting process
Centering rings: Cut and zinc-plated sheet metal
Working temperature:-30°C to +80°C
On request, all our bell housings can be supplied with specific coating or surface treatment to make them also fully suitable under rough circumstances.
Available in aluminium, for general industrial power transmission applications, an additional range of noise reduction equipment exists for noise and vibration sensitive applications.
Bellhousings made from cast iron and cast aluminum and a range of exotic materials, units specifically designed for the most aggressive of environments.
A complete range of equipment also exists to allow the connection of diesel, petrol and air motors to any driven component.
Drive line harmony - achieve the best results to transmit mechanical power from A to B, transmit mechanical power from the driver to the driven.
Wide range of bellhousings, in large numbers kept in stock for prompt delivery.
