Your Non‑Standard Bearing Partner – Customization, Flexibility and Quality
In the world of precision engineering, off‑the‑shelf standard bearings do not always fit. Special dimensions, unique preload requirements, application-specific materials—these needs arise frequently in custom machinery, prototypes, and specialized equipment.
Yet many major bearing groups impose high minimum order quantities and long lead times for non-standard sizes, leaving smaller customers with few good options.
At Luoyang Ouna Bearing, we take a different approach.
Customization Is Our Core Competency
Our flexible manufacturing capabilities allow us to accept small to medium batch custom orders—from one‑off prototypes to production runs. Our engineering team works directly with you to understand your application requirements and translate them into precision bearing solutions.
We regularly develop non-standard bearings across our entire product range:
Crossed roller bearings with custom dimensions, preload specifications, or materials
Rotary table bearings with integrated features or specialized performance parameters
Four-point contact ball slewing bearings for unique turntable designs
Thrust cylindrical roller bearings for unusual load requirements
Harmonic reducer bearings tailored to specific drive systems
Bearings for humanoid robots designed to meet exact joint cavity dimensions
Quality Without Compromise
Custom does not mean lower quality. All our non-standard bearings are manufactured to the same rigorous standards as our standard catalog products—precision grades P5, P4, and P2, high-purity bearing steel, precision heat treatment (HRC 60-62), and stringent quality control throughout the production process.
The Ouna Advantage
Flexible MOQ – No large minimum orders required
Short Lead Times – Faster than traditional custom suppliers
Engineering Support – Direct technical consultation from design to production
Full Traceability – Complete quality documentation for every custom order
From Luoyang to the World
Since our founding in 2014, we have been serving customers across Europe, America, and Southeast Asia. Our bearings are widely used in high-precision CNC rotary tables, industrial robots, automation equipment, medical instruments, and precision measurement devices.
If your standard bearing supplier says “no” to your custom requirements, talk to us. We are ready to engineer the solution you need.
