89310 -TV INA cylindrical roller thrust bearing

INA 89310-TV Cylindrical Roller Thrust Bearing (Reinforced Series)

The INA 89310-TV is a high-performance thrust bearing designed to accommodate exceptionally heavy axial loads acting in a single direction. It belongs to the 893 series, which features a reinforced design and higher load capacity compared to standard configurations. A key advantage is the glass-fiber reinforced polyamide 66 cage (TV), which reduces weight, ensures quieter operation, and minimizes heat generation. Due to the linear roller contact, this bearing offers maximum axial rigidity, essential for precision industrial mechanisms.

Application

• Machine Engineering: Axial support for machine tool spindles and high-pressure screw actuators.
• Automotive: Gearboxes and power transmission systems in heavy-duty vehicles.
• Automation: Rotary tables and manipulators requiring high axial stiffness in compact dimensions.
• Energy Sector: Vertical shaft bearing support for industrial pumps and generators.
• Heavy Equipment: Presses and conveyor systems subjected to significant vertical forces.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: 89310-TV.
• Dimensions: 50 mm (ID) × 95 mm (OD) × 31 mm (Total height).
• Cage Type: TV – Glass-fiber reinforced Polyamide 66.
• Load Type: Unidirectional axial loads only.
• Design: Separable (simplifies independent mounting of washers and the cage assembly).

Features and Benefits

• Reinforced 893 Series Design: Offers higher load ratings than the 811/812 series for the same bore size.
• Optimized TV Cage: Ensures low rolling resistance, leading to energy savings and extended lubricant life.
• Extreme Rigidity: Linear roller contact guarantees minimal deflection under full load.
• Ease of Installation: The ability to mount components separately significantly shortens assembly and maintenance time.
• SCHAEFFLER Premium Quality: Guaranteed highest manufacturing precision and long fatigue life.

Why Choose This Product

By choosing the INA 89310-TV bearing, you are investing in the uncompromising quality of the Schaeffler Group. In applications where standard thrust bearings struggle with pressure, the reinforced 893 series provides a reliable foundation. The polyamide cage ensures smoother and quieter machine operation, directly improving operational comfort and protecting other components from vibration.
