Deep-groove Ball Bearings

Product catalog summary

Overview: The document discusses NACHI's environmentally-friendly deep-groove ball bearings, which comply with ELV and RoHS directives, ensuring they are free from hazardous substances like hexavalent chromium. These bearings are designed for high performance and reliability in industrial machinery, particularly under high-speed and high-temperature conditions.

Specifications: The bearings feature NACHI's original high-performance grease and heat-resistant nitrile rubber seals. The new grease formulation offers twice the service life at 120°C compared to conventional grease, maintaining low noise and low torque properties. The nitrile rubber seals are designed to maintain sealing performance at high temperatures, reducing dust intrusion and extending bearing life.

Performance Testing: Tests on the 6203-2NKE bearing at 10,000 rpm with a radial load of 500 N at 120°C showed improved performance with the new rubber seals, allowing a 10% increase in the allowable temperature limit. Another test with the 6206-2NSE bearing under muddy water conditions at 1,000 rpm demonstrated less than 10% dust intrusion, indicating superior sealing performance at high temperatures.

Product Range: The document lists various bearing models, including 6000-2NSE9, 6200-2NSE9, and 6300-2NSE9, among others, with specifications for limiting speed, grease lubrication, and load ratings. These bearings are available with contact and non-contact rubber seals, as well as shields.

Contact Information: The document provides contact details for NACHI's global offices, including locations in the USA, Canada, Mexico, Europe, Asia, and Australia, ensuring accessibility for international customers.

Quest, for Higher Performance and Reliability Recent industrial machinery trends show an increasing need for bearings capable of handling higher speeds and higher temperature conditions. NACHI QUEST brand deep-groove ball bearings meet these changing demands. Heat-resistant rubber seals At high temperatures, rubber hardens degrading the seal performance. This allows foreign matter to enter the bearing. New heat-resistant nitrile rubber seals maintain sealing performance at high temperature. NACHI original high performance grease Modifying the base oil improves high temperature performance without...
