Abstract
A coiled tubing injector apparatus for inserting and/or removing coiled tubing from a well head comprising a first injector column and a second injector column forming a central pathway within a frame. The first and second injector columns each comprise an inner and outer band, the outer band containing a plurality of rolling elements for engaging the coiled tubing and the inner band creating drive force to energize the outer band. The inner band further comprises a wear plate designed to sustain the majority of wear for less costly maintenance and repair of injection heads.
