Gbm manufacturing pvt ltd is one of the major manufacturers of variety of mechanical power transmission couplings & expansion joints in india. The coupling product range includes gear coupling, pin-bush coupling, resilient coupling, disc coupling, tyre coupling and in expansion joints it includes non-metallic fabric type, multi layer fabric belt, metallic & rubber. For metallic expansion joint the company follow ejma standard. Non-metallic expansion joints are manufactured as per astm standard. "gbm hi-torque" type resilient couplings are in use in all types of industrial applications over many years with success.Such a resilient coupling comprises mainly two hubs, grid spring and covers to protect the spring, the grid spring element is so designed that it provides required resiliency for variable flexibility of a coupling and considerable damping properties making the coupling very suitable for drives involving high shock loads to the extent of 80%. Misalignment that inevitably occurs between rotating shafts, which are independently supported, is also taken care of by the spring element within allowable limits.Dimensions given in the tables are approximate and pertain to standard couplings of gbm range, but tailor-made couplings with hubs of longer or shorter lengths, seal & grub screws can also be supplied as per requirement of individual customer.
