A reversible puller has legs that turn over, so the same tool grips the outside of a pulley and the inside of a bore. That doubles what one puller covers and is the reason to choose one over a fixed-leg tool at the same reach. It also means one tool covers a pulley and a bearing race rather than needing two.
Reach is the sizing figure and runs 75mm, 100mm, 150mm and 200mm across the triple leg range. Reach is how far behind the part the legs will engage, and a puller that will not reach past the component has no purchase whatever its capacity. Both figures appear on the listing rather than one being implied by the other.
Bar type twin leg pullers are quoted differently, as spread by reach: 80 x 100mm, 120 x 100mm, 150 x 150mm and 200 x 150mm. The first figure is how far apart the legs open and the second is how far they extend, and both have to suit the part. Sealey run the SGP ladder across the reaches with matching centre bolts.
Sets are the sensible purchase where the work varies, at three and four pieces covering a range of reaches with one centre bolt. A three jaw wheel bearing puller at 12 to 38mm covers the small end.
