Type Gear Couplings
Brand Name Continental ContiTech
Color Black with matt finish
Material Cast Iron FG 200

Continental Flexible Gear Couplings offer efficiant transmission of mechanical power and are capable of compensating parallel, angular and axial misalignment of coupled shafts. This coupling consists of two Hubs with curved external teeth engaging with internal spur teeth of the outer Sleeves bolted together through high tensile Steel Bolts using a Gasket in between.

Hubs and Sleeves are machined from forged / cast Carbon Steels. Gear teeth are generated using CNC Machines shophisticated Gear Shapers and back-lash values are chosen to ensure mechanical flexibility as well as smooth torque transmission. Continental Gear Couplings are supplied with teeth induction hardened to the required degree as a standard and are distinguished this feature.

‘O’ Rings at the end of the hubs ensure sealing of lubricants inside the coupling while preventing entry of dust. Continental couplings are suitable for both grease and Oil lubrication. While Lithium based Greases with EP additives are recommended for operating temperatures up to 80°C, EP Gear Oils can be used for temperatures above 80°C

  • All Steel flexible geared couplings for high power & high torque applications in industries.
  • Backlash Values chosen to accommodate angular, parallel & axial misalignment.

Type Tyre Couplings
Brand Name Continental ContiTech
Material Nytrile Rubber Tyre

Continental Tyre Couplings embody all desirable features of and ideal flexible coupling. They are torsionally elastic & can accommodate simultaneous parallel, angular & axial misalignments without imposing undue loads on adjacent bearings. Flexible Rubber Tyre dampens vibrations & torsional oscillations while absorbing shoscks.

Power & Bore Range : Standard Range covers Power Capacity up to 57 kW at 100 rev/min and bores up to 150 mm.bigger sizes up to CTT – 250 to cover power ratings up to 130 kW at 100 rev/min & shafts up to 190mm can be supplied on demand.

Misalignment capacity : Parallel misalignment up to 4.8mm. Angular misalignment up to 4 & axial misalignment (End float) up to 6 mm depending on size of coupling.

Standard Tyres in high performance compound withstand temperatures up to 50 C. For high temperature applications with Oil & Grease contamination, Neoprene Tyres which are Oil & Heat resistant(up to 70 C) can be supplied.
