61810-2Z-Y INA deep groove ball bearing

INA 61810-2Z-Y Thin Section Deep Groove Ball Bearing

The INA 61810-2Z-Y is a high-precision rolling element belonging to the thin-section bearing series. With a 50 mm bore and an outer diameter of only 65 mm, it offers an exceptionally small cross-section. This model features dual non-contact metal shields (2Z), which protect the raceways from coarse contaminants while maintaining very low frictional torque. The Y suffix indicates a solid brass cage, which significantly enhances durability under vibration and high-speed conditions.

Application

• Automation & Robotics: Robotic arm joints and rotary mechanisms with limited installation space.
• Bicycle Industry & E-mobility: Bearings for e-bike motors and lightweight electric vehicles.
• Optics & Electronics: Precision measuring devices and scanners requiring low mass for rotating parts.
• Aerospace: Control mechanisms where every gram of weight saving is critical.
• Medical Equipment: Diagnostic and dental apparatus requiring smooth, quiet operation.
