Why Manufacturers Choose OTT
We don't just make bearings — we engineer solutions that fit seamlessly into your product line. Here's what sets us apart as your custom bearing manufacturer.
Full In-House Manufacturing
From raw steel to finished bearing — forging, turning, grinding, heat treatment, assembly, and testing all under one roof. No outsourcing means tighter quality control and faster turnaround.
IATF 16949 Quality System
Our quality management system meets the highest automotive standard. Every batch undergoes 100% inspection with automated testing equipment calibrated to P6/P5 precision grades.
Proprietary Carbonitriding
Our C-A heat treatment technology extends bearing lifespan by 5–10× compared to conventional processing. Validated by a 1,004-hour endurance test for a Russian OEM client.
Private Label & Packaging
Custom branding, packaging design, and labeling. We produce under your brand identity — from individual box printing to bulk pallet configuration.
Cross-Reference Compatibility
Our bearings cross-reference to SKF, FAG, KOYO, NTN, NSK, SNR, and BCA standards. Drop-in replacements that meet or exceed OEM specifications.
Flexible Terms & Logistics
MOQ from 1,000 pcs. FOB Ningbo/Shanghai. T/T or L/C accepted. Standard orders ship in 30–45 days. Expedited production available for urgent needs.
OEM Collaboration Process
From initial inquiry to ongoing production — a streamlined process refined over 15 years of OEM partnerships.
Requirements
Share your bearing specifications, application details, annual volume, and quality requirements. We assign a dedicated project engineer.
Engineering Review
Our R&D team evaluates feasibility, recommends optimal materials and heat treatment, and prepares a technical proposal with cross-reference mapping.
Samples & Testing
We produce prototype samples for your validation. Full dimensional and performance test reports included. Typical sample lead time: 7–15 days.
