Features of precision Exclusive CNC machined bearings lathe machine part

Bearings (including bearing rings, rolling elements, cages, and housings) are core components of mechanical equipment, and their machining quality directly determines rotational accuracy, load-bearing capacity, service life, and operating noise. Ganyuan Hardware, relying on its five-axis CNC machining center and combining years of experience in precision bearing component processing, has summarized the following core advantages of five-axis CNC machining for custom bearings:

Features of precision Advanced CNC machined bearings lathe machine part

I. Advantage of One-Step Molding for Complex Bearing Structures

Bearing components are mostly high-precision rotating structures, including raceways, flanges, mounting holes, lubrication grooves, and other features. Traditional machining requires multiple clamping operations, leading to accumulated errors. Five-axis CNC machining enables:

Complete machining of inner and outer rings and end faces in a single setup: All features of the bearing rings, such as raceways, flanges, sealing grooves, retaining grooves, and mounting holes, are completed in the same operation.

Eliminate errors from multiple setups: Ensures coaxiality of the inner and outer ring raceways and perpendicularity of the end faces to the axis.

Compatible with various bearing accessories:

Deep groove ball bearing rings (inner and outer rings, sealing grooves, retaining grooves)

Angular contact ball bearing rings (with locking jaws, raceway angles)

Cylindrical roller bearing rings (with flanges, raceways)

Tap roller bearing rings (inner and outer ring tapered surfaces, flanges)

Thrust bearing rings (raceway planes, positioning steps)

Bearing housings/bearing supports (mounting flanges, positioning stops, lubrication holes)

Special bearings (thin-walled bearings, non-standard sizes, stainless steel bearings)

II. High Precision and Rotational Performance Advantages

Bearing precision directly determines rotational smoothness and noise. Five-axis CNC machining can achieve:

Machining accuracy up to ±0.003mm (higher for ultra-precision)

Inner and outer ring raceway roundness ≤ 0.002mm, ensuring uniform force distribution on the rolling elements

Raceway roughness up to Ra 0.2-0.4μm (with ultra-precision lamination), reducing friction and noise

Inner and outer ring coaxiality ≤ 0.005mm, ensuring zero runout during rotation

End face parallelism ≤ 0.003mm, ensuring accurate axial positioning

Flange angle tolerance ≤ ±0.5°, ensuring precise guidance of the rolling elements

Equipped with professional equipment such as roundness testers, profile testers, roughness testers, coordinate measuring machines, and bearing vibration detectors, all goods are inspected before shipment.
