CBX Split Sleeves - FTI RailTec

CBX Split Sleeve Cold Expansion is performed by inserting a mandrel, pre-fixed with a disposable solid-film lubricated sleeve, into a hole and then pulling the mandrel back through the sleeve. The internally lubricated split sleeve creates a radial plastic flow around the hole and protects it from damage.

Each CBX sleeve may only be used once.
Manufactured from stainless steel.
Each sleeve is internally pre-lubricated with a proprietary dry-film lubricant.
Identification is provided by an electroetched model number on each sleeve.

To purchase CBX split sleeves, please provide your hole diameter and its working tolerance (in tenths of a millimetre) using the form on the right. Contact our customer service team if you have any queries.
