THK 58cm (22.75") Linear Bearing Rail with SSR20 Bearing Blocks. Bearing blocks have four holes in a 32mm square. The rails measure 20mm wide by 15.5mm tall.
This unit has some surface rust. These are not stainless or coated and rather unforgiving to high humidity (the rust happened virtually overnight). The bearing blocks move smoothly and firmly, they could probably use a grease charge.
Item weight is 3.58 lb.
Condition: Light surface rust. Probably need oiling.
