Abstract

A piston support portion (146) for a piston assembly (140) of a rodless cylinder (100) is provided according to the invention. The piston support portion (146) includes a support body (147) substantially matching a shape of the piston assembly (140) and configured to be positioned between a piston center portion (126) and a piston end portion (160). The piston support portion (146) further includes a plurality of guidance portions (152) extending from a circumference of the support body (147). The plurality of guidance portions (152) are configured to contact or nearly contact a piston bore (107) of the rodless cylinder (100) and guide the piston assembly (140) as it reciprocates in the piston bore (107).
