The NSK FWJ series needle cage is a precision component that keeps the needle rollers separated and guided in needle roller bearings. Its function is to ensure the correct distribution of loads and prevent direct contact between needles, which reduces friction and wear. It is used in applications where radial space is limited and high load capacity is required, such as transmissions, pumps and industrial machinery. MR Accesorios Industriales sells this series with NSK quality.
The FWJ series designation consists of the letters FWJ followed by a hyphen and a numeric sequence that identifies the main dimensions of the cage. For example, FWJ-172113 corresponds to a cage with an inner diameter of 17 mm, an outer diameter of 21 mm and a width of 13 mm. Likewise, FWJ-182417 has an inner diameter of 18 mm, an outer diameter of 24 mm and a width of 17 mm. These numbers provide guidance on the size and allow you to select the right cage for each application.
NSK FWJ series needle cages are used in a wide variety of industries in Argentina, such as automotive, metalworking, food and agricultural machinery. They are found in gearboxes, hydraulic pumps, compressors, electric motors and transmission equipment. Their compact design makes them ideal for tight spaces where high radial loads and moderate speeds must be supported. MR Accesorios Industriales sells them for replacement and industrial maintenance.
To select the right cage, take into account the dimensions of the bearing and the type of needles it will house. It is essential to verify the inner diameter, outer diameter and width, as well as the number and size of the needles. During mounting, ensure precise alignment and adequate lubrication to prevent premature wear. The cage must fit without excessive play and allow the needles to rotate freely. Careful mounting extends the service life of the bearing and reduces vibration.
NSK FWJ series needle cages can be interchanged with those from other brands that follow the same dimensional nomenclature, such as SKF, FAG or NTN, as long as the dimensions and needle type match. It is advisable to verify the equivalence with the original part number or consult a specialist. At MR Accesorios Industriales we advise you to find the cage compatible with your application, maintaining the quality and performance of the equipment.
