COM3(T) is a commercial COM series spherical bearing with a 0.1900" bore (B) and 0.5625" OD (D), used in industrial machinery, agricultural equipment, hydraulic cylinders, and structural pivot applications that require high static load capacity.
COM3(T) has a 0.1900" bore (B) and a 0.5625" outer diameter (D).
COM3(T) has a body width (W) of 0.281" and an inner race width (T) of 0.218", ball diameter is 0.406", and flat OD (O) is 0.293". Approximate weight is 0.014 lb.
COM3(T) is rated at 3,250 lb static radial load with a misalignment angle of ±11.0°.
The ball is 52100 bearing steel with a precision-ground surface and hard chrome plating. The race is alloy steel with an oil-coated finish; the COM series includes a lubrication groove and oil hole for external lubrication.
Adding the 'T' suffix (e.g. COM3T) selects the PTFE-lined variant for lower-maintenance, reduced-friction articulation instead of the standard metal-to-metal race. SYZ also offers a chromoly race (FKS series), a stainless steel race (COM-SS series), a zinc-plated race option on request, and a metric equivalent in the COMA-M series.
