Precision in Motion, Engineered for Compact Excellence Since 1950
IKO Nippon Thompson Co., Ltd., founded in 1950 and Japan's pioneer in needle roller bearings and linear motion systems, dominates as a global leader with over 70 years of innovation. Specializing in ultra-compact, high-load solutions, IKO integrates patented materials science, sub-micron grinding, and self-lubricating technologies to deliver unmatched reliability in space-constrained and harsh-environment applications. Certified to ISO 9001/14001, IKO supplies 150+ countries from automated production hubs across Japan, Asia, and the Americas, backed by 48-hour OEM technical support19.
Space-Optimized Design:
Needle Roller Geometry: Rollers with 3-10× length-to-diameter ratios enable 30% smaller radial profiles vs. standard bearings, ideal for compact machinery (e.g., robotics, EV transmissions)48.
J-Fit Interchangeability: Patented housing tolerance (J7/H7/K7) ensures 100% interchangeability, reducing micro-movement by 30% and extending lifespan by 200%9.
Extreme Environment Resilience:
C-Lube Technology: Porous resin lubrication system enables maintenance-free operation for 5 years or 20,000 km, reducing downtime in CNC and semiconductor equipment3.
Hybrid Ceramic Options: Si3N4 balls in high-speed series (e.g., HA-II) support 100,000+ rpm with 15-30% lower energy loss6.
Ultra-Precision Engineering:
SpinShot Lubrication: Oil-air systems suppress heat rise at 40,000 rpm, cutting noise by 3-5 dB and gas consumption by 50%3.
P2/P4 Tolerance Grades: Sub-micron accuracy for machine tool spindles and medical robotics6.
Global Applications:
Machine Tool Spindles, Industrial Robotics, Semiconductor Manufacturing, Automotive Transmissions, Aerospace Actuators, and Medical Devices.
