Expander Rings

Need a quote for expander rings? Click here.Expander rings from Royal Rubber have been used by countless industrial customers to improve efficiency and save time in production.  These mandrel filler rings were originated by the professionals at Royal Rubber to adjust the size of the mandrel, eliminating the need for filler plates or changing mandrels.

Our expander rings are easily installed, mounting quickly without the need for special lifting equipment. Once in place, these custom made adaptive parts allow your mandrel to handle coils of various ID, even odd sizes.

Expander rings not only increase the versatility of your equipment, but provide valuable protection.  Made from specially formulated rubber that resists tears and abrasion, our expander rings extend the life of your expansion mandrel surfaces.  Designed to provide uniform gripping force, our filler rings prevent costly damage to inner wraps as well.

Our custom-made expander rings are manufactured for durability and quality. They are built to perform under the toughest conditions.  Designed with horizontal grooves to permit maximum expansion, our customers take advantage of more versatile uses.  Our expander rings are available in custom widths from less than 8” to larger than 48” to fit your uncoiler specifications and desired mandrel OD.
