Cylindrical Rollers
Precision Cylindrical Rollers for High-Load Applications
Cylindrical rollers are flat-ended rolling elements with a length that is typically one to three times the diameter. Their structure is designed for high radial load capacity and minimal deformation, making them essential in demanding mechanical systems.
Atlas Ball & Bearing is a leading supplier of precision cylindrical rollers used in roller bearings, automotive seat slides, rockbit drills, gear systems, and heavy-duty industrial assemblies across the automotive, aerospace, and general engineering sectors.
Available Size Range
Diameter: 2.5mm (0.0984″) to 70mm (2.7559″)
Length: 4mm (0.1575″) to 70mm (2.7559″)
Cylindrical Rollers
Available Materials
Cylindrical rollers are manufactured in a range of high-performance materials to suit application needs:
Chrome Steel (AISI 52100) – High load capacity, excellent hardness, and wear resistance
Martensitic Stainless Steel (AISI 420) – Combines corrosion resistance with high surface durability
Austenitic Stainless Steel (AISI 302, 316) – Non-magnetic, hygienic, and corrosion-resistant
Tool Steel (AISI S2, M2) – Designed for extreme loads and impact-prone environments
Our diverse material range enables us to meet performance requirements across industries—whether you’re seeking high strength, corrosion resistance, or non-magnetic properties.
