61826-2RS-Y INA deep groove ball bearing

INA 61826-2RS-Y Thin Section Deep Groove Ball Bearing

The INA 61826-2RS-Y is a highly specialized rolling component from the thin-section series (ISO 10). With an impressive 130 mm bore diameter and a width of only 18 mm, it enables significant space savings without compromising rotational precision. This model features contact rubber seals on both sides (2RS), effectively protecting the raceways from dust and moisture. The unique solid brass cage (Y) provides superior ball guidance, enhanced vibration dampening, and resilience to higher operating temperatures.

Application

• Automation & Robotics: Main rotation axes for large industrial robots where low weight and compact size are critical.
• Precision Machine Tools: Rotary tables and spindles requiring a large hollow shaft diameter.
• Aerospace & Optics: Radar systems, scanners, and antenna positioning mechanisms.
• Renewable Energy: Compact generators and pitch mechanisms in wind turbines.
• Medical Equipment: Large-scale diagnostic devices such as CT scanners.
