Needle cages in the NTN KV series hold and guide the needle rollers inside bearing and transmission assemblies. They suit designs where radial room is tight but the assembly still has to carry a high load. MR Industrial Accessories LLC supplies this series to maintenance and purchasing teams.
Reading a KV code helps you confirm you are ordering the right cage. The first number gives the needle circle diameter, then the letters KV mark the series. The numbers that follow separate width from outer diameter, and the closing suffix covers design variants or needle count. If any part of the code is unclear, send the full part number and we will check it with you.
Typical users include automotive, machine tool, transmission and agricultural equipment. Repair shops often fit these cages when rebuilding gearboxes, pumps, compressors and rolling systems, where the replacement has to match the original exactly. MR Industrial Accessories LLC serves workshops, plants and maintenance operations across the United States and in several Latin American countries.
Selection comes down to a few measurements: needle diameter and length, pitch circle diameter, and how the assembly is sealed. Lubrication and shaft alignment also affect how long the cage lasts, so they are worth checking before installation. Once mounted, confirm the needles turn freely and the cage sits correctly in place. Our team can walk you through the selection if needed.
Interchange with other brands is possible when the standardized dimensions and load capacity line up, so compare measurements and material type before substituting. For a quote, send the original part number or the dimensions you measured, and we will advise on an equivalent. Quotes are handled by WhatsApp or email, with prompt replies.
