Lovejoy 69790405273 Coupling Cover Set 4 Inch Alloy Steel

Product Description

The LOVEJOY 69790405273 is a universal horizontal coupling cover set designed to enclose and protect jaw-style or sleeve couplings in industrial and mechanical drive applications. Built from alloy steel, this cover set fits a 4-inch hub diameter and is rated for up to 422 inch-pounds of torque capacity at a maximum speed of 6,000 RPM. It is sized to coupling size code 1020. Maintenance mechanics, millwrights, and industrial service technicians install this cover to shield coupling elements from debris, reduce personnel hazard near rotating components, and comply with machine guarding requirements.

This cover set is suited for horizontal drive shaft installations where a durable, close-fitting metal guard is required. Typical applications include pumps, fans, compressors, and conveyor drives in light commercial and industrial settings. The universal design accommodates standard coupling arrangements without requiring custom fabrication. It ships as a complete cover hardware set ready for field installation.
