81113 -TV INA cylindrical roller thrust bearing

INA 81113-TV Cylindrical Roller Thrust Bearing (Polyamide Cage)

The INA 81113-TV is a high-precision thrust bearing designed to accommodate heavy axial loads acting in a single direction. The unit consists of a cylindrical roller and cage assembly along with two washers: the shaft washer and the housing washer. The standout feature of this model is the glass-fiber reinforced polyamide 66 cage (TV). This design ensures excellent roller guidance, reduces the overall bearing weight, and provides significantly quieter operation, which is critical for modern high-efficiency drive systems.

Application

• Machine Construction: Axial support for shafts in machine tools, presses, and extruders.
• Industrial Automation: Rotary tables and manipulators requiring high axial stiffness in a compact design.
• Automotive Industry: Power transmission systems and final drives.
• Energy Sector: Vertical shaft bearing support for generators and industrial pumps.
• Logistics: Heavy-duty lift mechanisms and roller conveyor systems.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: 81113-TV.
• Dimensions: 65 mm (ID) × 90 mm (OD) × 18 mm (Total height).
• Cage Type: TV – Glass-fiber reinforced Polyamide 66.
• Load Type: Unidirectional axial loads only.
• Design: Separable (facilitates independent mounting of washers and the roller assembly).

Features and Benefits

• Superior Axial Rigidity: Cylindrical geometry provides a linear contact surface, minimizing deflection under load and ensuring machine precision.
• Advanced TV Cage: Polyamide offers lower friction, leading to reduced operating temperatures and extended lubricant life.
• Ease of Installation: Separable components significantly simplify assembly and maintenance procedures.
• High Load Capacity: Performance ratings far exceed standard axial ball bearings of similar dimensions.
• German Engineering: Manufactured to Schaeffler's rigorous standards, ensuring repeatable, top-tier quality.

Why Choose This Product

By choosing the INA 81113-TV bearing, you are investing in a product from the industry leader, the Schaeffler Group. Thanks to the modern polyamide cage, this bearing handles dynamic speed changes more effectively and offers higher mechanical efficiency than versions with heavier metal cages. It is a reliable solution that protects your machinery from premature wear and ensures stable operation even under significant axial pressure.
