G R Spider

Raj Trading Corporation is one of the leading Dealer, stockist, suppiler & Distributor of a comprehensive range of G R Spider in and around Chennai. The wide range of G R Spider which are supplied by the Raj trading corporation are listed below.

The G R Spider coupling concept gives a reliable, smooth power transmission without torsional oscillation / vibration and so protects the connected machines. Due to the complete flexibility and ductility of the elastomer ring, it compensates for parallel and angular displacements as well as to absorb longitudinal movements of the shafts.

The involute teeth of the elastomeric inserts are crowned in order to avoid edge pressure on the tooth flanks and so avoid undesirable axial thrust. The puncture proof spider coupling can be loaded extremely high since the elastic elements are submitted to compression and not to bending moments of force. The elastomer gear ring, made of a newly developed Simrit-Polyurethane of various degrees of shore hardness, has important advantages in comparison with the standard polyurethanes. It is non-ageing, with resistance against hydrolysis (can be used in tropical conditions), non-abrasive, has a high self-damping effect and is also resistant to oil and ozone. It can be used with temperatures ranging from -400 °C to +1000 °C.

G R Spider couplings can be used for horizontal as well as for vertical shaft connections, for reversing, intermittent service and are electrically insulating. The operating characteristics and the durability of the coupling are very positively influenced by the high overall precision of the machining, especially the claws, unbalance is reduced to a minimum, running is improved and service life considerably increased.
