89313 -TV INA cylindrical roller thrust bearing

INA 89313-TV Cylindrical Roller Thrust Bearing (Reinforced Series)

The INA 89313-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, which offers higher load capacity and stiffness compared to standard thrust bearings. The standout feature is the glass-fiber reinforced Polyamide 66 cage (TV). It ensures excellent roller guidance, weight reduction, and significantly quieter operation with lower friction, resulting in less heat generation within the bearing arrangement. Thanks to the linear contact of the rolling elements, this model guarantees uncompromising stability for 65 mm diameter shafts.

Application

• Machine Engineering: Axial support for spindles in machine tools, presses, and vertical drills.
• Energy Sector: Shaft bearings for industrial pumps, compressors, and generators.
• Automation & Robotics: Compact rotary tables and joints requiring high axial rigidity.
• Lifting Technology: Crane hook rotation mechanisms and winches under heavy vertical pressure.
• Automotive Industry: Drive systems and main transmissions for heavy machinery and commercial vehicles.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: 89313-TV.
• Dimensions: 65 mm (ID) x 115 mm (OD) x 30 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 washers and the cage assembly).

Features and Benefits

• Increased Load Rating (893 Series): Allows for handling greater forces than the 812 series with the same bore size.
• Optimized TV Cage: Polyamide ensures lower frictional torque, reducing energy consumption and extending lubricant life.
• High Rigidity: Cylindrical roller geometry eliminates micro-deflections, critical for machine precision.
• Ease of Maintenance: Modular design allows for independent fitting of shaft (WS) and housing (GS) washers.
• SCHAEFFLER Quality: Manufactured from premium bearing steel, ensuring reliability in the harshest conditions.
