B 0.3125 / D 0.7500COM5(T) is a commercial COM series spherical bearing with a 0.3125″ bore (B) and 0.7500″ OD (D). Body width (W) = 0.375″, inner race width (T) = 0.281″. Ball diameter = 0.562″. Flat OD (O) = 0.419″. Approximate weight: 0.030 lb.
Rated at 6,475 lb static radial load with ±12.0° misalignment angle. The 52100 bearing steel ball is precision ground, heat treated, and hard chrome plated. The alloy steel race is oil coated and drilled and grooved for external lubrication. PTFE liner available — add ‘T’ suffix (e.g., COM5T) for the PTFE-lined, self-lubricating variant. Used in industrial machinery, agricultural equipment, hydraulic cylinders, and structural pivot applications requiring high static load capacity.
PTFE-lined variant available (suffix ‘T’). Chromoly (FKS series) and stainless steel (COM-SS series) race options available. Zinc plated race option available on request. Metric equivalent is the COMA-M series.

COM5(T) is a commercial COM series spherical bearing with a 0.3125" bore (B) and 0.7500" OD (D), used in industrial machinery, agricultural equipment, hydraulic cylinders, and structural pivot applications that require high static load capacity.
COM5(T) has a 0.3125" bore (B) and a 0.7500" outer diameter (D).
COM5(T) has a body width (W) of 0.375" and an inner race width (T) of 0.281", ball diameter is 0.562", and flat OD (O) is 0.419". Approximate weight is 0.030 lb.
COM5(T) is rated at 6,475 lb static radial load with a misalignment angle of ±12.0°.
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. COM5T) 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.
