MARTIN SPROCKET Jaw Coupling Spiders

Features

Dayton Spider Coupling Inserts

• They are used with metal jaw couplings for uniform power transmission while maintaining structure and position.
• These Hytrel spider inserts offer excellent oil & impact resistance and are capable of withstanding temperatures ranging from -60 to 70 degrees F.
• Their assembly comprises two jaw hubs and a spider for transmitting higher torque and preventing misalignment (angular & parallel) between the connecting shafts.

Lovejoy Snap Wrap Spiders

• These flexible snap wrap spiders permit close shaft separation up to the hub's maximum bore size.
• They have urethane or SOX (NBR) rubber construction that ensures abrasion resistance and protection against dirt, grease & moisture.
• Their snap wrap design allows easy removal of the units without moving the hubs.

Ruland Manufacturing Curved Jaw Coupling Spiders

• They dampen shocks and accommodate misalignment (angular, parallel & axial) between coupling hubs.
• Their polyurethane construction does 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.
