F-225035.1 Cylindrical Roller Bearing For A11V190 Hydraulic Pump Width - 27mm

F-225035.1 is a special split crescent half-moon needle roller bearing, also known as curved segment roller bearing, specially matched for axial variable displacement hydraulic pumps of construction excavators and loaders. It adopts split semi-circular outer race + integrated needle retainer combined structure, unique segmented arc design perfectly fits the curved installation cavity of hydraulic pump swash plate assembly.

All needle rollers, semi-circular outer race and retainer are manufactured with fully quenched GCr15 bearing steel, ultra-precision mirror grinding rolling surface, uniform needle load distribution, strong resistance to alternating impact pressure generated by high-pressure hydraulic pump reciprocating operation. Compact split layout saves internal pump body installation space, stable low-friction rotation, effectively reduce pump internal heat generation and abnormal wear, extend hydraulic pump service cycle. Widely used for excavator main hydraulic pump, engineering machinery variable plunger pump, heavy load hydraulic rotary pump core rotating matching parts.
