Custom mandrel sleeves built to fit YOUR mandrel — not an off-the-shelf stock size. Hot vulcanized, seamless construction. Rubber or polyurethane base. Custom durometer matched to mandrel OD, coil ID tolerance, and line tension. The CoilGrip family covers uncoiler/recoiler service across coil coating and metals processing.
Hot vulcanized rubber sleeves have zero seams — no failure points where the sleeve can split. Built around a mandrel form in the shop, then cured under heat and pressure to a continuous monolithic cylinder.
Available in rubber and polyurethane formulations across a broad hardness range — matched precisely to your mandrel OD, coil ID tolerance, and line tension requirements. Proper fit means uniform compression, consistent sleeve life, and no improvised field shimming.
Engineered surface characteristics deliver reliable traction on coil ID surfaces during unwinding and rewinding cycles. Maintains consistent grip under variable tension loads — preventing slippage, coil walk, and mandrel damage.
Formulated to resist the abrasion, tearing, and compression set that prematurely fail standard sleeves. Maintains original geometry and grip characteristics over repeated coil cycles. The CoilGrip case study customer went from 1-month replacement cycles to 4–6 months.
Rubber formulations offer superior flexibility and conformability for irregular mandrel surfaces. Polyurethane delivers higher load capacity, abrasion resistance, and dimensional stability where wear and heavy tension are the primary failure drivers.
