81213 -TV INA cylindrical roller thrust bearing

INA 81213-TV Cylindrical Roller Thrust Bearing (Polyamide Cage)

The INA 81213-TV is a high-precision thrust bearing engineered to handle massive axial loads in a single direction. The assembly consists of a cylindrical roller and cage assembly along with shaft and housing washers. The standout feature of this model is the glass-fiber reinforced polyamide 66 cage (TV). This advanced material reduces the bearing's weight, ensures quieter operation, and provides superior performance at high speeds compared to standard metal cages.

Application

• Machine Engineering: High-pressure machine tool spindles, rotary tables, and screw actuators.
• Automotive Industry: Power transmission systems in heavy-duty vehicles and work machinery.
• Energy Sector: Axial support for vertical shafts in generators and turbines.
• Mining & Quarrying: Components for drill rigs and crushing equipment subject to constant axial stress.
• Automation: Axial load support in heavy-duty industrial manipulators.
