Tritan Com 4 Ball-joint Spherical Plain Bearing 0.25 in Bore

Product Description

The TRITAN COM 4 is a ball-joint spherical plain bearing designed for applications requiring articulating load transfer in tight radial spaces. The bearing features a 0.25-inch bore diameter and a 0.688-inch outer diameter, with a 0.344-inch width. It carries a dynamic load capacity of 4,950 pounds and a static load capacity of 4,950 pounds, making it suitable for moderate-duty mechanical linkages and pivot assemblies. Both the ball and raceway are constructed from steel, and the bearing is factory-lubricated with oil. This part is installed by millwrights, maintenance mechanics, and industrial technicians working on mechanical motion systems.

The COM 4 fits residential and light commercial mechanical assemblies where a compact, low-friction pivot joint is required. Typical applications include control linkages, actuator rod ends, and articulating structural connections. The 13.5-degree maximum ball swivel angle accommodates moderate misalignment between mating components. This bearing is suited for installations where precise bore alignment and controlled angular motion are priorities.

Key Features

• 0.25-inch bore diameter for standard shaft fitment
• 4,950-pound dynamic and static load capacity for moderate-duty service
• Steel ball and steel raceway construction for durability
• 13.5-degree maximum ball swivel for misalignment accommodation
• 0.5-inch ball diameter within a 0.688-inch outer diameter envelope
• Oil-lubricated from factory for immediate service readiness

Compatibility

Designed as an OEM-style replacement or direct-fit spherical plain bearing for mechanical linkage and pivot assemblies requiring a 0.25-inch bore, 0.688-inch outer diameter, ball-joint type bearing.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with plain bearing press-fit procedures. Depressurize, de-energize, and mechanically lock out the host assembly before removing the existing bearing. Use a properly sized bearing press or arbor tool to seat the bearing without applying force through the ball element. Verify bore housing tolerances against manufacturer specifications before installation.
