18mm Spherical Bearing

The FK ROD ENDS 18mm Spherical Bearing (part number COM18M) is a precision-engineered rod end assembly designed for applications requiring smooth articulation and load distribution. With an 18mm inner diameter and 35mm outer diameter, this spherical bearing delivers reliable joint movement in high-stress environments where traditional rigid connections would fail. Built from chrome-plated steel, it resists corrosion and maintains consistent performance in saltwater and high-moisture conditions common to marine and motorsports applications.

The COM-M series design provides 23mm thickness with a spherical articulating head that accommodates angular loads and misalignment without binding or seizing. The 0.22 lbs weight and compact 1.5 x 1 x 1.5 inch footprint make this bearing suitable for suspension linkage, steering components, and control rod applications where space and weight efficiency matter. Chrome plating extends service life by protecting the steel base from rust and oxidation, a critical advantage in saltwater environments where untreated steel fails rapidly.

This spherical bearing serves marine repair shops, performance boat builders, offshore fishing vessel operators, and motorsports professionals who demand repeatable articulation without play or degradation. It's equally at home in steering systems, trim-tab linkages, or suspension geometry corrections where angular deflection must be absorbed smoothly. Serious boaters and technicians rely on this type of precision bearing to maintain control and safety when standard rod ends wear out or fail under dynamic load.

The 18mm ID matches OEM and aftermarket applications across marine, automotive, and powersports categories. When specifying spherical bearings for replacement or upgrade, matching the inner diameter and load rating ensures the bearing seats correctly and distributes force evenly across its articulating surface. FK's COM-M series is recognized for consistent quality and long service life in demanding environments.
