INDUSTRIAL FLUID APPLICATIONS
Where Industrial Fluids Matter
Bearing microstructure, dimensions, appearance and surface quality are shaped by heat treatment, precision machining and final protection.
Carbonitriding
Bearing ring material and effective wall thickness determine the required cooling profile. Controlled cooling supports the target microstructure and reduces deformation risk, particularly for thin-walled and complex rings.
Induction Hardening
Induction hardening of hub bearings and related components involves rapid heating and high-pressure spray conditions. Controlling foam, tramp oil and concentration changes helps maintain consistent cooling and stable production.
Deformation and Appearance
Cooling rate and uniformity affect bearing ring deformation and dimensional stability. Carbon deposits, oxides and tramp oil may lead to discoloration and surface residue.
Grinding, Superfinishing, Cleaning and Rust Prevention
Grinding and superfinishing establish the final accuracy and functional surfaces of bearings. Cleaning removes oil, particles and carbon residue, while rust prevention protects components during handling, packaging and storage.
PRACTICAL APPLICATION RESULTS

APPLICATION RESULT 01
Distortion Control of Carbonitrided 6308/01 Bearing Outer Rings
After quenching with KR468G, the troostite level was below Grade 1, with 95% of samples maintaining ovality within 0.15 mm. KR498 achieved Grade 1, with all samples within the same limit. Both quenchants controlled outer-ring distortion while meeting microstructure requirements, supporting dimensional stability in downstream precision machining.
