ABSTRACT:
A shaft roller, including a shaft, a casing with two ends, and further, for each of the two ends of the casing, a bearing support, an end bearing, and a protective cap. The roller further includes a plurality of inner tubes, a plurality of ring holders, and a plurality of inner bearings. For each end of the casing, a groove is cut into the inner periphery of the casing for holding a peripheral outward extension of the bearing support. For each end of the casing, the bearing support has a wheel body with spokes, surrounding the end bearing and holding the end bearing with an inward projection. The end bearing is a needle roller bearing around the shaft, having a needle cage with a plurality of needles. For each end of the casing, the protective cap prevents dust and humidity from entering the casing, being attached to the bearing support by a plurality of blocks. Inside the casing, the plurality of inner tubes surrounds the shaft, with one of the plurality of ring holders being inserted between every two inner tubes, supporting the casing. One of the plurality of inner bearings is located between each ring holder and the shaft. Thus mechanical stability and low friction are ensured for various lengths of the casing.
