Bell Housing Extension Bracket Assembly

Description

The Extension bracket series EB are designed for coupling Low pressure hydraulic pumps having flanges as per ISO standards to Polyhydron make high pr. pumps (1R,2R,11R and 12R series).These Extension brackets are precisely machined to reduce misalignment of coupled shafts.The correct alignment of the shafts along with the cushioned power transmission through a resilient spider increases the life of the bearings of the Hi-Low pr.pump coupled. The construction also reduces the noise generation considerably.
