89314 -TV INA cylindrical roller thrust bearing

INA 89314-TV Cylindrical Roller Thrust Bearing (Reinforced Series)

The INA 89314-TV is a high-performance rolling unit engineered to accommodate exceptionally heavy axial loads in a single direction. It belongs to the reinforced 893 series, offering superior load capacity and stiffness compared to standard thrust bearings. The core feature is the glass-fiber reinforced Polyamide 66 cage (TV). It ensures precise roller guidance, weight reduction, and significantly quieter operation with lower friction, directly translating to less heat generation within the bearing arrangement. Thanks to the linear contact of the rolling elements, this model guarantees uncompromising stability for 70 mm diameter shafts.

Application

• Machine Engineering: Main axial support for spindles in heavy-duty machine tools, presses, and vertical drills.
• Energy Sector: Shaft bearings for vertical generators, compressors, and large industrial pumps.
• Automation & Robotics: Compact rotary tables and positioners requiring extreme axial stiffness.
• Lifting Technology: Crane hook rotation mechanisms, winches, and screw jacks under massive vertical pressure.
• Automotive Industry: Drive systems and main transmissions for commercial vehicles and heavy machinery.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: 89314-TV.
• Dimensions: 70 mm (ID) x 125 mm (OD) x 34 mm (Total height).
• Cage Type: TV – Glass-fiber reinforced Polyamide 66 (lightweight and quiet).
• Load Type: Unidirectional axial loads only (High Load).
• Design: Separable (allows independent mounting of shaft WS and housing GS washers).

Features and Benefits

• Maximum Load Rating (893 Series): Optimized design for handling much greater forces than the common 812 series.
• Optimized TV Cage: Polyamide ensures lower frictional torque, reducing energy consumption and extending lubricant life.
• Extreme Rigidity: Cylindrical roller geometry eliminates micro-deflections, critical for heavy-duty machine precision.
• Ease of Maintenance: Modular design allows for independent fitting of rings and the assembly, simplifying technical service.
• SCHAEFFLER Quality: Manufactured from premium bearing steel, ensuring operational safety in the most demanding conditions.
