Jaw Coupling Spiders

Lovejoy snap wrap spider couplings provide shaft-to-shaft connection for power transmission and accommodating parallel & angular misalignment in industrial machinery, electric motors & compressors. These jaw couplings feature radially removable elastomeric cushions for ease-of-maintenance and no metal to metal contact for wear minimisation. SOX (NBR) rubber / urethane construction provides resistance against oil, sand, dirt, grease & moisture while ensuring fail-safe operation, even upon elastomeric cushion failure. These snap wrap spidersare capable of delivering torque up to 3510 inch-lb and the collar configuration of these snap wrap spiders can achieve the same speed as standard couplings since the collar is attached to one hub. Raptor Supplies, a trusted distributor of Lovejoy snap wrap spiders, also offers coupling spacers, jaw couplings, sleeve gear couplings, gaskets, hydraulic tanks and related accessories.

Ruland Manufacturing curved jaw coupling spiders are designed to dampen shocks and accommodate misalignment (angular, parallel & axial) between coupling hubs. The spider couplings fit between two coupling hubs for a secure connection. They are made from polyurethane, do not require lubrication and can hold up against dirt, sand, grease, oil & moisture. These coupling inserts are used with coupling hubs and can handle torque ratings up to 8000 RPM. Choose from a wide range of coupling spiders, available in 4 and 6 arm options on Raptor Supplies.

Dayton spider inserts are used in conjunction with metal jaw couplings for uniform power transmission while maintaining their structure and position. These hytrel spider inserts offer excellent oil and impact resistance and are capable of withstanding temperatures ranging from -60 to 70 degrees F. The complete assembly comprises two jaw hubs and a spider for transmitting higher torque and preventing misalignment (angular & parallel) between the connecting shafts. Choose from an array of these jaw coupling spiders, available in lengths ranging between 0.433 & 0.866 inches.

Dayton jaw coupling inserts are used for dampening shock & vibrations between coupling hubs to accommodate small amount of misalignment including angular, parallel and axial. The complete assembly requires two jaw hubs and a spider for transmitting higher torque and prevent misalignment between the connecting shafts. These Buna-N inserts provide excellent oil and impact resistance and are capable of withstanding temperatures up to 212 degrees F. Choose from an extensive range of these jaw coupling inserts, available in lengths ranging from 0.433 to 0.866 inches.
