A sheave system comprising: a sheave body, the sheave body comprising: a groove; a sheave body outer diameter; a sheave body inner diameter; one sheave sleeve selected from at least four sheave sleeves fixedly attachable to the sheave body inner diameter, each of the at least four of the sheave sleeves comprising: a sleeve bore; a sleeve outer diameter that is about the same as the sheave body inner diameter as to allow a fixed attachment between the sleeve and sheave body; a sleeve inner diameter; one bearing selected from at least four bearings fixedly attachable to the sleeve inner diameter, each of the bearings comprising: a bearing outer diameter that is about the same as the sheave body inner diameter as to allow a fixed attachment between the bearing and the sleeve, and a bearing inner diameter. A method of making a sheave system, the method comprising: determining an outer diameter of a sheave body; determining a rope size; selecting a sheave body; determining an outer diameter of a shaft; determining a bearing type; selecting a bearing; selecting a sheave sleeve; attaching the sheave sleeve to the sheave body; and attaching the bearing to the sheave sleeve.
