Oliver’s SIZE RIGHT® Precision Cylinder Sizer separates product by width and thickness down to the most accurate screen tolerances in the industry – between +.000″ and -0.003″. These include some screens that will have 4 sizes within a 64th (Example 8/64ths, 8.25/64ths, 8.5/64ths, 8.75/64ths, 9/64ths). All components on the SIZE RIGHT are heavy-duty and long lasting and cylinders are custom-made for all types of precision sorting.

All cylinders are protected behind optional quick release, auto-shutoff safety doors. A hinge design option allows operators to lower the doors without removing them, resulting in a much easier cleaning process.

Maintenance-free notched and timed Kevlar belt offers superior wear life over a chain or V-belt. Reduces the number of moving parts and eliminates leaky gear boxes entirely. Provides twice the support with notched cog and dedicated bearings at each end of the cylinder.

These rollers push out lodged material that is not removed by the primary flapper cleanout. Pushes stuck kernels back into the overs fraction. Provides superior results, maximum throughput and safety compared to other designs.

Cylinders can be changed out in less than a minute. A single key allows you to pull out the cylinder without cumbersome spring loaded mechanisms, fork tools or shear pins.

Allen-Bradley® PowerFlex® 40 VFD speed control provides a degree of sizing precision unlike any other sizer. Includes digital display when switching between different seed types.
