Bearing Race / Transmission Shaft Bushing

Central stepped bores with internal serrations or splines provide precise mechanical interlocking for shaft connections. This cylindrical geometry is typical for bearing inner/outer races, pulleys, or transmission bushings where torque transfer and rotational stability are critical.

Manufacturing relies on CNC turning to achieve concentricity between the outer diameter and the central bore, followed by secondary operations for the internal features. Critical checkpoints include the tolerance of the serrated interface, surface finish of the rolling or sliding contact areas, and dimensional consistency across batches. The factory utilizes precision lathes and boring equipment to maintain tight tolerances required for power transmission components.

F&W Machine Manufacturing specializes in OEM machining for the elevator, automotive, and construction machinery industries, with a strong export history in bearing and power transmission parts. Production follows ISO 9001 quality standards, utilizing advanced inspection tools like optical comparators and micrometers to verify datum references. Please provide dimensioned drawings specifying material family (e.g., steel, alloy) and heat treatment requirements to receive an accurate quote.
