About Dynaroll
About Dynaroll
Dynaroll Corporation was founded in 1988 and has grown into one of the world's largest independent suppliers of miniature bearings, serving automotive, medical, aerospace, and other high-precision industries that need small-diameter bearings held to tight tolerances. The company's manufacturing footprint spans Sylmar, California and Wuxi, China, giving it dual-region production for customers sourcing globally.
Dynaroll's catalog includes ball bearings, bearing sub-assemblies, bronze bushings, and plastic bearings, and the company holds both FDA critical approvals for its medical customers and PPAP approvals for automotive customers, credentials that matter when a bearing is going into a surgical device or a safety-critical vehicle component. Dynaroll was acquired by Providien in January 2013 and now operates as part of Amphenol Critical Medical Technologies, giving it backing from a larger precision manufacturing organization while retaining its bearing specialization.
Dynaroll bearings show up in medical instruments, precision motors, and compact mechanical assemblies wherever a standard-size bearing won't fit the available space. On ChatMRO, buyers can search by Dynaroll part number or describe the bore size and application and get matched to the right bearing or sub-assembly.

What makes a bearing a "miniature" bearing?
A miniature bearing typically refers to bearings with very small bore diameters, often under 10mm, used in compact assemblies like medical instruments, small motors, and precision mechanisms where standard-size bearings won't fit. Dynaroll specializes specifically in this small-diameter category rather than general industrial bearing sizes.
