81114 -TV INA cylindrical roller thrust bearing

INA 81114-TV Cylindrical Roller Thrust Bearing (Polyamide Cage)

The INA 81114-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 quieter operation, which is critical for modern high-speed drive systems.

Application

• Machine Construction: Axial support for shafts in machine tools and industrial presses.
• Automation: Rotary tables and manipulators requiring high axial stiffness.
• Automotive Industry: Power transmission systems and final drives.
• Energy Sector: Bearing support for rotors in vertical generators and pumps.
• Logistics: Heavy-duty conveyor systems and industrial lifts.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: 81114-TV.
• Dimensions: 70 mm (ID) × 95 mm (OD) × 18 mm (Total height).
• Cage Type: TV – Glass-fiber reinforced Polyamide 66.
• Load Type: Unidirectional axial loads only.
• Design: Separable (simplifies the mounting of individual components).

Features and Benefits

• Superior Axial Rigidity: Cylindrical geometry provides a linear contact surface, minimizing deflection under load.
• Friction and Noise Reduction: The polyamide cage (TV) generates less heat and runs significantly quieter than metal cages.
• Ease of Installation: Separable washers and roller assemblies shorten assembly time.
• High Efficiency: Precision-ground raceways lead to lower energy consumption for the equipment.
• SCHAEFFLER Quality: Guaranteed top-tier metallurgical standards and manufacturing precision.
