Product Features of Radial Bearings

Design Characteristics

Radial spherical plain bearings requiring maintenance(steel-on-steel) are made of carbon chromium steel 

and are hardened and phosphatedexcept for series GEBK..S,COM…, GEBJ…S and GEK…XS-2RS.

The innerand outer ring sliding contact surface are treated with molybdenum

disulphide.The outer ring is fractured so that it can be sprung open when theinner ring is inerted.

Outer and inner ring of CEK…XS-2RS are made ofcarbon chromium steel and are hardened.

Outer rings of GE…XS/K andGEK…XS-2RS, held together by retaining rings. 

To facilitate efficient lubrication, all bearings have an annular groove 

and lubrication holes in eachring except those of the E design. 

Bearings of the 2RS design are fitted withnylon seals or rubbings seals of polyester elastomer at both sides.

Outer ringof series COM… and GEBJ…S are made of carbon steel, pressed around theinner ring; 

Inner ring of carbon chromium steel, hardened, slidingsurface treated with chromium plating.

Outer rings of series GE…C,GEG…C,COM…T and GEBJ..C are made ofcarbon steel,

pressed around the inner ring,with sliding surface of PTFEcomposite material; 

Inner rings of carbon chromium steel, hardened,Outer rings of series GE…C,GEG…C,COM…T and GEBJ..C are made of

carbon steel, pressed around the inner ring,with sliding surface of PTFEcomposite material; 

Inner rings of carbon chromium steel, hardened,silding surface treated with chromium plating.

Outer rings of series GE…ET-2RS,GEG…ET-2RS and GEZ…ET-2RS are made of carbon chromiumsteel,

fractured, hardened and phosphated, with sliding surface treated withchromium plating.

The 2RS design with two seals at both sides. Outer rings ofseries GE…ET/X and

GE…ET-2RS/X are made of stainless steel, fractured,with sliding surface of PTFE fabric; Inner rings of stainless steel,

hardened, the 2RS design with two seals at both sides. Outer rings ofseries GE..XT/X

and GE…XT-2RS/X are made of stainless steel, axiallysplit twice, held together by retaining rings, 

with sliding surface of PTFEfabric; Inner rings of stainless steel, hardened, 

the 2RS design with twoseals at both sides. Outer rings of series GE…XF/Q,GEC..XF/Q and

GEH..XEF..XF/Q are made of carbon chromium steel, axially split twice, heldtogether by retaining rings, 

hardened and phosphated, sliding surfacetreated with chromium plating;

Inner rings of copper alloy, with slidingsutface of solid lubricant. 

Outer ring of series GEH…HE/Q is made ofcarbon steel, radially split twice, held together by screws, 

phosphated,sliding surface treated with chromium plating; Inner ring of copper alloy,

with sliding surface of solid lubricant. make the use of steel-on-steel bearing inadvisable.

Permisslble Operating Temperature Range

Steel-on-steel、steel-on-PTFE composite material and steel-on-PTFE fabric radial spherical 

plainbearings can be used at temperature-50℃~+150℃,spherical plainbearings 

with seals can be used at temperature -30℃~+130℃. 

At highertemperature, the load carrying capacity will be reduced.
