At Bearing.ml, we focus strictly on the production of high-precision linear motion bearings and accessories. Operating from our specialized production line in China, we manage every phase—from raw steel rod cutting and precision grinding to automated assembly and heat treatment.
Our engineering processes ensure tight tolerance controls and geometric accuracy. This makes our components highly compatible with automation equipment, CNC machinery, routers, and high-load packaging systems.
We utilize high-purity GCr15 bearing steel to ensure wear resistance and uniform internal structure.
From centerless grinding to inner raceway super-finishing, every step is rigorously monitored.
Anti-rust oil processing and vacuum sealing prevent humidity damage during marine transport.
Asian (LM) and European (LME) dimensions. High rigidity, low noise, and excellent smooth running.
Round (LMF), Square (LMK), and Oval (LMH) flange types. Saves mounting space and housing parts.
Standard closed (SC/SMA) and open types (SBR/TBR). Aluminum housings ready to bolt down.
Induction hardened, precision ground shafts and pre-drilled aluminum supporting guide rails.

Our centerless grinding and sorting process ensures that internal clearance tolerances comply with ISO standards, preventing binding or play in linear assemblies.
Both ball bearings and matching linear shafts undergo induction heating to achieve a surface hardness of HRC 60-64. This minimizes wear over extended operations.
All components are cleaned, oiled with high-grade preservative lubrication, and individually packed in plastic sealed bags to prevent oxidation during sea freight.
