A roller for use in a spinner apparatus for installing a pipe segment in a well pipe including a core member having a central aperture, and a plurality of annular members arranged in stacked relation over the core member. The plurality of annular members are secured together. The core member includes a generally tubular section having a first end and a second end, and a flange section extending radially outwardly of the tubular section between the first and second ends. The flange section has a greater diameter than the tubular section. The flange section includes a plurality of holes formed therein. Each of the annular members has a plurality of holes formed therein. The holes of the annular member are aligned with the holes of the flange section. Fasteners extending through the holes in the flange section and the plurality of annular members. A first cap member is positioned at one end of the plurality of annular members. A second cap member is positioned at the opposite end of the plurality of annular members. The fasteners extends through these cap members and the annular members so as to maintain the annular members together in stacked relationship. Each of the annular members is formed of either an elastomer or a molded organic material. Each of the annular members is formed of split annular members fitted together around the core member.
