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 rotodisc flexible coupling is the engineered standard in non-lubricated couplings for pumps ,compressors ,fans and blowers ,refrigeration and air-conditioning equipment ,other rotating equipment . Gbm rotodisc flexible coupling transmit mechanical power to driven machines through shaft mounted hubs connected by the coupling and flexible disk packs. Both angular and axial misalignment are accommodated by the flexible disc packs rotodisc flexible couplings, for medium duty applications requiring moderate shaft separations consist of three main parts : hubs - 2 in number , ss shims - 1 pack / 2 packs , high tensile steel fasteners - 1 set . The hub is made of carbon steel and the ss shims from 300 series of stainless steel which provide a high degree of strength and resistance towards corrosion. Fasteners are made of high tensile steel. The centre spacer assembly is provided to ensure excellent dynamic balance. Advantage:never needs lubrication ; quick, easy installation and alignment ; ss shims - simple installation and removal ; standard spacers [reel] to meet industrial shaft separations ; visual inspection without dismantling ; long hubs for taper bores .
