30 mm (1.18 inch) outer rim fits snugly into metal guide brackets
15 mm (0.59 inch) body width absorbs day to day sliding pressure

💡 How do sealed track bearings stay handy for continuous slide motion?
Your quiet sliding action comes from built-in shields that keep dust away from the spinny balls.
- Hardened chrome steel tracks handle heavy pushes without bending out of shape
- Rubber edge seals trap fresh grease inside so you ignore routine top offs
- Tight manufacturing gaps stop grit from scratching rail surfaces during rough work
- Ready-to-roll grease packs save labor hours since you mount them straight out of the box
