NACHI Bearings: Advanced Solutions for High-Speed and High-Temperature Industrial Applications

With the ever-evolving demands of modern industrial machinery, bearings must withstand higher speeds and temperatures without compromising performance or longevity. NACHI, a leading Japanese manufacturer, has responded to these challenges by introducing innovative solutions and setting a new standard for high-performance bearings.

Quest Standard: Excellence in Every NACHI Bearing

All NACHI deep groove ball bearings meet the rigorous "Quest" standard, ensuring world-class quality and reliability. This Quest designation signifies a commitment to superior materials, state-of-the-art technology, and premium lubricants, all developed and produced in-house by NACHI. This integrated approach results in remarkable stability, durability, and low noise levels, alongside a commitment to environmental sustainability.

Advanced Seals for High-Temperature Durability

Standard seals can become brittle at high temperatures, allowing contaminants to enter the bearing, which can degrade performance. To address this, NACHI has developed high-temperature-resistant seals made from specially formulated nitrile rubber. These seals retain their flexibility and effectiveness in extreme conditions, ensuring optimal protection and preventing contaminants from entering.

NACHI's High-Performance Grease

A vital element for bearing performance, NACHI's proprietary grease has been optimized for high-temperature endurance. Thanks to modifications in the base oil, this grease performs exceptionally at elevated temperatures (up to 120°C), with twice the durability of previous formulas. Environmentally friendly and compliant with ELV and RoHS standards, NACHI’s grease contains no hazardous substances like hexavalent chromium, making it safe for both machinery and the environment.

Versatility in Design: A Wide Range of Types and Dimensions

NACHI offers an extensive range of deep groove ball bearings, suitable for a myriad of industrial applications. These bearings are available in open, shielded, and sealed variants, with either contact or non-contact seals. The inner diameter range spans from 10 to 200 mm, with popular series including 6800, 6900, 6000, 6200, and 6300. This versatility makes NACHI bearings an ideal choice for various applications, from high-speed machinery to high-temperature environments.

Maintenance-Free Bearings for Long-Term Reliability

NACHI's sealed deep groove ball bearings are pre-lubricated, eliminating the need for frequent maintenance. This feature not only reduces downtime but also ensures long-term, reliable performance under normal operating conditions. These bearings are designed to support radial and axial loads in any direction, even at high rotational speeds, which is essential for complex machinery and automotive systems.
