FEATURES & APPLICATIONS

Precision mechanical assemblies (PMAs)are a wide range of bearing assemblies that incorporate high-precision Minebea ball bearings. PMAs provide both high precision and high product quality by making maximum use of super-precision machining technology and specialized knowledge in bearing assemblies accumulated through in-house ball bearing development and production..

MINIMIZES ASSEMBLY PROCESS

Product is delivered in the best possible state since bonding and preloading control eliminate problems such as bearing damage, poor runout accuracy, looseness, and preload step omissions that are prone to occur during assembly. Also reduces in-process defects.

MINIMIZES INSPECTION PROCESS

Reduces inspection process tasks since quality checks are no longer needed for each assembly process.

LIGHTENS THE PARTS MANAGEMENT & ORDERING TASK LOAD

Ordering spare parts is no longer necessary so inventory can be reduced and logistics expenses lowered.
