NSK needle cages and components

FWF-101410 and WJ-101410 are listed as needle cages; FTRA-1024 is listed as a needle thrust bearing. Each code combines letters, a hyphen and numbers. Matching numbers do not prove identical construction. Preserve FWF, WJ and FTRA without dividing the sequence into assumed dimensions. Product name and assembly drawing identify contact surfaces and component scope.

In a compact transmission, a cage may run between surfaces belonging to other mechanism parts. At a thrust position, identify the faces receiving axial force instead. Both require raceway identification before replacement. Record washers, rings and spacers in their original order during dismantling. Their condition matters: replacing a cage neither repairs a damaged raceway nor independently defines shaft guidance.

For a quote from MR Accesorios Industriales, state reference, quantity and whether associated parts are required. Add dimensions, individual component photographs and a view of the housing or shaft acting as a raceway. Describe radial or axial loading according to the machine design. This context and the drawing prevent loose components from being mistaken for a complete bearing or every reference from being assigned the same configuration.
