GY specializes in high-precision needle rollers and cylindrical rollers ranging from 0.5mm diameter × 1.5mm length to 6mm diameter × 40mm length, with tolerances as tight as 0.001mm. Our flat rollers are manufactured from bearing steel, stainless steel, stainless iron, high-carbon steel, ZOCM, and other custom materials to meet demanding operational requirements.
1. Ultimate Space Optimization
Ultra-Thin Profile: Diameter-to-width ratios exceed 5:1, reducing axial space usage by 50–70% — ideal for compact designs (e.g., robotic joints, aerospace actuators).
High Integration: Dense roller arrangements maximize load capacity within limited installation spaces.
2. Lightweight Breakthrough
Advanced Materials: Titanium alloy cages, ceramic rollers, or hollow structures reduce weight by 40–60%, significantly lowering rotational inertia (e.g., drone motors, racing drivetrains).
System-Level Weight Savings: Every 1kg weight reduction saves approximately $3,000/year in fuel costs in aerospace applications.
3. High Rigidity & Precision Motion
Multi-Roller Load Sharing: Increases radial stiffness by 20–30%, enabling high-precision positioning (e.g., semiconductor equipment, medical CT scanners).
Nanoscale Surface Finish: Profile accuracy achieves 0.1μm-level precision, with motion errors <1.5μm.
4. Exceptional Dynamic Performance
Low Centrifugal Effects: Flat geometry minimizes centrifugal expansion at high speeds, supporting DN values >800,000 (e.g., electric spindles, turbo-molecular pumps).
Optimized Lubrication: Thin profiles facilitate efficient oil film formation, reducing friction and thermal rise by 15–25%.
5. Adaptability to Extreme Conditions
High-Temperature/Chemical Resistance: Silicon nitride ceramic rollers (withstand 1,200°C) or stainless steel variants (excellent corrosion resistance).
EMC Compatibility: Non-magnetic models for MRI equipment, with magnetic interference <0.1μT.

1. Ultimate space optimization
Ultra-thin cross-section : The diameter-to-width ratio can reach over 5:1, and the axial space occupied is reduced by 50%~70%. Flat rollers are suitable for compact designs (such as robot joints and aviation actuators).
High integration : Within the same installation space, the load-bearing capacity is improved through dense roller arrangement.
2. Lightweight breakthrough
Material innovation : Flat rollers use titanium alloy cages, ceramic rollers or hollow structures, reducing weight by 40% to 60% and significantly reducing the inertia of rotating parts (such as drone motors and racing car transmission systems).
System-level weight reduction : Every 1kg weight reduction can save approximately $3,000 in fuel costs per year in the aviation field.
3. High rigidity & precision movement
Multi-roller collaborative load-bearing : radial stiffness is increased by 20%~30%, suitable for high-precision positioning (such as semiconductor equipment, medical CT machines).
Nano-level surface treatment : flat roller profile accuracy reaches 0.1μm, motion error <1.5μm.
4. Excellent dynamic performance
Low centrifugal force effect : The flat structure reduces centrifugal expansion during high-speed rotation, with a DN value exceeding 800,000 (such as electric spindles and turbomolecular pumps).
Optimized lubrication design : Thin-section oil film is easier to form, and the friction temperature rise is reduced by 15%~25%.
5. Adaptability to special working conditions
Extreme environments : Optional silicon nitride ceramic rollers (temperature resistant to 1200°C) or stainless steel (corrosion resistant).
Electromagnetic compatibility : Non-magnetic models are used in MRI equipment, with interference magnetic field <0.1μT.
Automobile industry: Components such as gearboxes, clutches, steering systems, engine camshafts, chassis suspensions, etc. use needle roller bearings (containing needle rollers) to achieve efficient transmission and support.
Mechanical manufacturing: needle rollers can adapt to the installation requirements of small spaces in the spindles and guide rails of machine tools, transmission parts of textile machinery, roller supports of printing machinery, etc.
Hydraulic and pneumatic equipment: The pistons, plungers and other moving parts inside hydraulic pumps and hydraulic motors use needle rollers to reduce friction and improve equipment efficiency.
Medical devices: The rotating or sliding structures of some precision medical devices require needle rollers to provide stable support and low-friction movement.
Engineering machinery: hydraulic cylinders and joints of excavators, loaders and other equipment. Needle rollers can withstand large loads and adapt to complex working conditions.
The core requirement of these scenarios is to use the slender structure of the needle roller to save space, while reducing equipment loss and improving operating efficiency through rolling friction.
