Rotex Coupling Manufacturer in North Korea

GR COUPLINGS

GR couplings are the three piece assembly of 2 no. Aluminium Alloy Cast Iron or Steel hubs and one Special Grade Polyurethane Spider. These three pieces are co-axially assembled to complete the GR coupling. After assembly these couplings becomes sufficient flexible, positive motion and power transmitting fail safe coupling elements. Due to polyurethane spider, both the metallic hubs are separated from each other to avoid there physical contact. This helps to avoid the electrical and frequency isolation of both the connected driver and driven elements.

GR hubs are available in Aluminium, Cast Iron and Steel Material. GR sizes from 19 to 28 are made from Aluminium Alloy & Steel material. GR sizes from 38 to 90 are made from Cast Iron & Steel Material.

GR hubs are manufactured with high precision machining. The jaws are machined with concave shape and entry chamfer for easy assembly. The concave shape in jaws of hub and the convex shape on the polyurethane spider allows for better angular, parallel and axial misalignment.

These hubs are available in un-bored, pilot bored, finish bore & key-ways, and with different styles of clamping arrangements as per customer requirements.

GS COUPLINGS

GS Couplings are the three piece assembly of 2 no. Aluminium Alloy or Steel hubs and one Special Grade Polyurethane Spider. These three pieces are co-axially and with certain positive pre-stress are assembled to complete the coupling. After assembly these couplings becomes sufficient flexible, backlash-free, positive motion and power transmitting fail safe coupling elements. Due to polyurethane spider, both the metallic hubs are separated from each other to avoid there physical contact. This helps to avoid the electrical and frequency isolation of both the connected driver and driven elements.

GS hubs are available in Aluminium and Steel Material. GS sizes from 9 to 38 are made from Aluminium Alloy material. GS sizes from 42 to 65 are made from Steel.

Hubs are manufactured with high precision machining. The jaws are machined with concave shape and entry chamfer for easy assembly. The concave shape in jaws of hub and the convex shape on the polyurethane spider allows for better angular, parallel and axial misalignment.

These hubs are available in un-bored, pilot bored, finish bore & key-ways, and with different styles of clamping arrangements as per customer requirements.
