The 6305-2RS is a high-performance, double-sealed deep groove ball bearing designed for applications requiring protection against dust and moisture. With precision engineering and durable materials, it ensures reliable operation in industrial, automotive, and agricultural machinery.
Double Rubber Seals (2RS):
Nitrile Rubber (NBR) Seals prevent contamination from dust, dirt, and moisture.
Extends bearing life in harsh environments.
Premium Material Construction:
Inner/Outer Rings & Balls: Chrome Steel (GCr15) for high wear resistance.
Cage: Nylon (PA66) or Steel (optional) for reduced friction and noise.
High Load Capacity & Speed:
Dynamic Load (Cr): 22.0 kN | Static Load (Cor): 11.5 kN.
Max Speed: 8,000 rpm (Grease), 10,000 rpm (Oil).
Wide Compatibility:
Direct replacement for SKF 6305-2RS, NSK 6305DDU, FAG 6305-2RSR.
Matches ISO 15:2011 standards.
