1. Solving Your Biggest Machining Challenges
Your machinery demands precise, compact, and durable components that can handle heavy radial loads in tight spaces. Traditional bearings often fall short when:
- Space is limited: Needle rollers' small cross-section fits where other bearings can't
- Load capacity is critical: Their high surface area distributes weight more effectively than ball bearings
- Speed matters: Reduced friction means better performance at high RPMs
- Reliability is non-negotiable: Consistent performance under shock loads and vibration
At YIDI Motion, we've engineered our metric needle roller bearings to address these exact pain points, with 30% better load distribution than standard alternatives.
"The right bearing can reduce your maintenance costs by up to 40% over the component's lifecycle." - Industrial Machinery Digest
2. YIDI's Metric Needle Roller Bearing Solution
Our metric needle roller bearings combine German engineering precision with Chinese manufacturing efficiency, delivering:
Superior Load Capacity
Handling 20% more radial load than standard bearings of the same size, thanks to optimized roller geometry.
Extended Service Life
Heat-treated alloy steel provides 50,000+ hours of operation under normal conditions.
Compact Design
Up to 70% smaller cross-section than ball bearings with equivalent load ratings.
Unlike competitors who cut corners on materials, we use 100% vacuum-degassed bearing steel (equivalent to AISI 52100) for all our metric needle roller bearings, ensuring consistency from the first unit to the millionth.

6. Engineering FAQs
Q: What's the difference between metric and inch needle roller bearings?
A: Metric bearings use millimeter measurements (e.g., 10mm ID) and conform to ISO standards, while inch bearings use fractional sizes (e.g., 3/8" ID). Metric is more common in global industrial applications due to its precision.
Q: Can these handle both radial and axial loads?
A: Needle roller bearings excel at radial loads. For combined loads, we recommend our needle roller thrust bearings or combined needle roller bearings (NAXK series).
Q: What's your minimum order quantity (MOQ) for custom sizes?
A: Our standard MOQ is 500 units for custom metric needle roller bearings, but we can accommodate smaller quantities for prototyping at a slightly higher unit cost.
Q: How do I select the right grease for my application?
A: We provide KF99-3 high-temperature grease as standard. For extreme conditions (-40°C to +150°C), we recommend our synthetic grease option. Our engineers can help match the right lubrication to your operating environment.
Q: What's your lead time for standard metric needle roller bearings?
A: For our most popular sizes (NA49xx, NA69xx series), we maintain stock and can ship within 3-5 business days. Custom sizes typically require 4-6 weeks.
