Project Overview
This project focuses on needle bearings designed to be used together with shoulder bolt and nut assemblies, forming a complete rotating connection solution.
Compared with standard standalone bearings, these needle bearings are optimized to match the bolt dimensions and assembly structure, ensuring smooth motion, reduced friction, and stable long-term performance.
Product Structure & Features
Each needle bearing consists of:
- Hardened drawn cup
- Precision needle rollers
- Hardened steel cage
This structure provides:
- High load-bearing capacity
- Compact design for limited space
- Low friction and smooth rotation
- Reliable performance under continuous operation
Typical Specification (Example)
- Size: 3/4″ ID × 1″ OD × 3/4″ Width
- Static Load Capacity: 4,950 lbs
- Dynamic Load Capacity: 3,450 lbs
We are able to produce multiple size series based on customer drawings or standard specifications.
Application
These needle bearings are typically used in:
- Mechanical linkages
- Rotating joints
- Industrial equipment assemblies
- Custom fastening systems
They are especially suitable for applications where:
- Space is limited
- Load capacity is critical
- Smooth rotation is required
Matching Assembly Supply
This product is commonly supplied together with our:
👉 Shoulder Bolt and Nut Assembly
In most projects:
- Bearing quantity is 2× the bolt assembly
- All components are designed to work together as a system
This ensures:
Simplified sourcing for customers
Better performance matching
Reduced installation issues
Production & Experience
This is a long-term repeat project:
- Nearly 20 years of manufacturing experience
- Multiple size series available
- Continuous repeat orders from customers
- Stable quality and mature production process
Quality Control
To ensure consistent performance:
- Incoming material inspection
- In-process dimensional checks
- Final inspection before shipment
All products are manufactured based on strict quality standards and customer requirements.
With nearly two decades of production, this product has proven its reliability across different industries and working conditions.
Order Information
- Quantity: Usually 2× of the matching bolt & nut assemblies
- Production: OEM based on drawings or standard sizes
