Stammford's low drag centralizers rollers are fixed on centralizer vanes such that the axis of rollers. The roller outer diameter is slightly larger than centralizer body outer dia. Rollers are capable enough to reduce considerable drag force due to low friction coefficient between well and centralizer. The small contact area of the rollers with the casing or borehole wall functions exceptionally well in under pressured conditions, where risk of differential sticking is high. High quality material provides excellent high temperature high-pressure performance and corrosion resistance, reducing the cost of replacement.

They also provide a profile for landing and bumping the wiper plugs at the end (after displacement).landing collar inserts have a profile to latch the wiper plugs in place to prevent them from rotating , locking or sealing during the process of drilling them out. For highly deviated or horizontal applications, the ball seat can be manufactured with a special profile to guide the ball seat. They are normally placed one or two joints above the nearest float collar.
