INA K series needle cages are components that guide and retain cylindrical needles in a radial arrangement. They are used in assemblies where radial space is limited and high load capacity is needed in a small volume. MR Accesorios Industriales supplies this INA line, an official brand that MR carries, backed by more than 80 years in the industrial sector. If you need to identify the right cage for your mechanism, send us the part number on WhatsApp and we will advise you.
The designation of INA K series needle cages is read directly: the letter K identifies the family and the number that follows indicates the needle diameter or the reference dimension of the assembly, depending on the case. For example, K10, K12, K14 and K15 correspond to different sizes within the same series. They do not include additional prefixes or suffixes in this basic nomenclature, so the complete part number is interpreted as the specific cage size. To confirm the exact equivalence with your drawing or sample, it is advisable to verify the part number with our technical team.
These cages are used in a wide variety of industrial applications in Argentina. They are found in gearboxes, pumps, compressors, machine tools, transmission equipment and lifting mechanisms. They also appear in support rollers, cams and oscillating systems where needles must be guided precisely. Industries such as automotive, metalworking, food and petrochemical use them to replace or manufacture compact rolling assemblies. MR Accesorios Industriales supplies them to serve both maintenance workshops and equipment manufacturers.
To select a K needle cage, take into account the diameter and length of the needles it will house, as well as the shaft and housing diameters. The cage must allow the needles to rotate freely and keep them aligned. It is essential to verify lubrication: these cages usually require oil or grease that guarantees a film between needles and raceways. During assembly, avoid impacts that deform the cage and make sure the needles roll without jamming. Alignment between shaft and housing also influences the performance and service life of the assembly.
Regarding equivalences and interchangeability, needle cages are identified by their dimensional designation, which may coincide between different manufacturers. However, it is not advisable to assume that a part number from another brand is identical without verifying tolerances and surface treatment. INA is a reference in this type of component, and its K series is often found in replacement catalogues. If you need to replace an existing cage, the safest approach is to compare the actual dimensions of the needles and the assembly, not just the part number. Our team can help you with that verification.
