Description
The Giflex Range of Internal Gear Couplings have Steel Sleeve with Hermetic seals at each end, enabling them to be used in many hazardous enviromental Conditions and providing a higher torque capacity range of 600nm to 90,000nm.
They are available in nine sizes and two design types, the GFA type having two removable internal gear hubs and the GFAS type have one fixed solid hub and one removable internal gear hub. Both the Steel Sleeve and the hubs are manufactured from hardened carbon steel with a tensile strength of 800n per m2.
Another feature is the CNC machining to DIN 3992 Class 7 Precision to provide the Crowning and Barrelling of the gear tooth form which eliminates tooth edge pressure and allows them to accommodate both Radial as well as Angular deviation or misalignment.
The stock range is available as a pilot bore coupling as either a short hub length or a long hub length or as a combination of each which allows for flexibility of spacing between shafts and can be re-machined to suit individual customer’s shaft sizes on quick lead times as required.
