81124 -TV INA cylindrical roller thrust bearing

INA 81124-TV Cylindrical Roller Thrust Bearing (High Axial Rigidity)

The INA 81124-TV is a high-performance rolling unit engineered to accommodate heavy axial loads acting in a single direction. As a Schaeffler Group product, it features top-tier manufacturing precision and fatigue life. The core of its design is the glass-fiber reinforced Polyamide 66 cage (TV), ensuring superior roller guidance, weight reduction, and quieter operation. The separable design allows for independent mounting of the shaft washer, housing washer, and roller assembly on 120 mm shafts.

Application

• Machine Tooling: Axial support for spindles in CNC machines, presses, and vertical drills.
• Energy Sector: Shaft bearings for industrial pumps, compressors, and large fans.
• Lifting Technology: Crane hook rotation mechanisms and winches under high vertical pressure.
• Automation: Heavy-duty turntables and positioners requiring high rigidity and motion precision.
• Mining Industry: Drive systems for construction and transport machinery under heavy loads.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: 81124-TV.
• Dimensions: 120 mm (ID) x 155 mm (OD) x 25 mm (Total height).
• Cage Type: TV – Reinforced Polyamide 66 (lightweight, quiet, low friction).
• Load Type: Unidirectional axial loads only.
• Design: Complete bearing (WS shaft washer, GS housing washer, K roller assembly).

Features and Benefits

• Extreme Load Capacity: Cylindrical rollers provide a much larger contact area than balls, allowing for massive axial force handling.
• Optimized TV Cage: Polyamide reduces friction, resulting in lower operating temperatures and extended lubricant life.
• High System Rigidity: Minimal deflection under load guarantees precise positioning of machine components.
• Modular Construction: Simplifies installation and removal by allowing independent fitting of the rings.
• Premium Quality: INA branding ensures reliability and compliance with the most stringent industrial standards.
