I.Introduction
A wireline roller stem is designed to replace conventional stem for operation in deviated well bores. The rollers on the stem run along the underside wall of the tubing. The use of rollers greatly reduces the friction that conventional stem would encounter.

III.Structure characteristics and application
The wireline roller stem is modified based on conventional stem, with milled slots to accommodate simple roller wheels. The wheels run on high tensile steel axle bolts, which are locked in position by roller pins.
