Needle roller cages in the NTN K series keep the rollers evenly spaced and guided inside a bearing, which lets you build a compact, rigid assembly where radial room is tight. MR Industrial Accessories LLC supplies this series and helps you match the cage to your shaft, housing and width.

The part number tells you the size. Take K4×7×7T2: the figures after the K are bore, outside diameter and width in millimeters, so 4 mm bore, 7 mm outside diameter, 7 mm width. The T2 ending points to a steel cage with a surface treatment. Every reference in the series covers one specific set of needles and dimensions.

Typical places these cages show up are pumps, compressors, electric motors, conveyors, machine tools, transmission equipment and appliances. Because the cage carries the rollers without a full inner or outer ring, the bearing envelope stays small while radial load capacity remains high.

When you select a cage, start with the shaft diameter, then the housing bore and the width you can fit. Mount it with the needles correctly oriented, apply the right lubricant, and check alignment and radial clearance against the load type. Sealing the assembly keeps contaminants out.

Cages in the K series follow a common dimensional nomenclature, so references from other makers with the same numbers can often be used instead. Send the complete part number or the three dimensions and the team will confirm the equivalent.
