KOYO Bearings:
KOYO utilizes materials that are specifically designed to maintain their mechanical properties in low-temperature conditions. These materials are resistant to brittleness and retain their functionality even in extreme cold.

NACHI Bearings:
NACHI employs materials that are selected for their ability to withstand low temperatures without compromising performance. These materials resist material contraction and maintain their structural integrity in cold environments.

  1. Lubrication Performance:

KOYO Bearings:
KOYO provides recommendations for selecting lubricants that remain effective in low-temperature conditions. Proper lubrication is crucial for reducing friction and preventing wear in cold environments.

NACHI Bearings:
NACHI offers guidance on choosing lubricants that can operate efficiently at low temperatures, ensuring that bearings maintain their performance even in extreme cold.

  1. Sealing and Shielding:

KOYO Bearings:
KOYO may offer bearings with advanced sealing and shielding mechanisms designed to protect against cold temperatures, ice, and moisture, thus ensuring long-term reliability in low-temperature environments.

NACHI Bearings:
NACHI provides bearings with effective sealing and shielding options to safeguard against cold-related issues and maintain consistent performance.

  1. Heat Generation and Friction Control:

KOYO Bearings:
KOYO designs bearings to minimize heat generation during operation in low-temperature conditions, helping to maintain a stable temperature range for optimal performance.

NACHI Bearings:
NACHI’s bearing designs may incorporate features that reduce friction and heat generation, ensuring bearings operate efficiently in cold environments.

  1. Application-Specific Solutions:

Both KOYO and NACHI offer specialized bearing solutions designed for specific low-temperature applications, ensuring that bearings are optimized for extreme cold conditions.

  1. Environmental Responsibility:

Both manufacturers prioritize environmentally responsible manufacturing practices, contributing to reduced environmental impact and sustainable production methods.


Operating in low-temperature environments demands bearings that can withstand extreme cold while maintaining performance and reliability. KOYO and NACHI have demonstrated their capabilities in providing low-temperature-resistant solutions suitable for various industries.

The choice between KOYO and NACHI bearings for low-temperature applications should consider factors such as material composition, lubrication recommendations, sealing mechanisms, and heat generation control. Both manufacturers prioritize the ability of their bearings to withstand extreme cold while delivering dependable performance.

Ultimately, the goal is to select the bearing manufacturer that offers the best combination of low-temperature resistance, lubrication support, and sealing technology, ensuring that machinery and equipment operate reliably and efficiently in challenging low-temperature environments, thus optimizing overall productivity and cost-effectiveness.
