B 4.252 / D 6.614GEZ107ES Spherical Bearing (Inch)
GEZ Product Overview
GEZ107ES is a fractured-race spherical plain bearing with a 4.252″ bore (B) and 6.614″ OD (D). Width (W) = 3.720″, inner race width (T) = 3.189″. Approximate weight: 18.54 lb.
Rated at 661,386 lb static radial load with ±1.0° misalignment angle. The 52100 bearing steel ball and race are both precision ground and protective coated. The fractured-race design allows the race to separate for ball installation, enabling use in high-load industrial applications where solid-race designs are impractical. Optional double rubber seals (2RS) available — order as GEZ107ES-2RS — for dust and contamination exclusion in harsh environments.
Double rubber seal option available (order as GEZ107ES-2RS). Metric GE..ES series available on request. Self-lubricating metric equivalents: GEC (standard width) / GEGC (wide series).

GEZ Frequently Asked Questions
What is GEZ used for?
GEZ spherical bearings are used in high-wear and increased-load industrial applications where fractured-race construction and strong radial support are required.
What makes GEZ different from standard commercial spherical bearings?
GEZ uses a fractured-race spherical bearing design for high-wear, increased-load applications, with protective-coated 52100 bearing steel components.
Are seals available for GEZ bearings?
Yes. Double rubber seals are available on supported sizes by adding the suffix -2RS, for example GEZ38ES-2RS.
What materials are used in GEZ spherical bearings?
GEZ uses a 52100 bearing steel ball and 52100 bearing steel race, both with protective coating for industrial wear resistance.
Are metric equivalents available?
Yes. Metric equivalents are available in the GE..ES and GE..ES-2RS series.
How do I choose the right GEZ size?
Start with the required bore, outer diameter, width, misalignment angle, and static radial load shown in the size chart, then confirm whether the sealed 2RS option is needed for the application.
