81208-TV INA Thrust Cylindrical Roller Bearing 40x68x19 mm

Product Overview

High-capacity axial roller bearing for demanding industrial applications

The 81208-TV INA thrust cylindrical roller bearing, sized 40 mm (ID) x 68 mm (OD) x 19 mm (width), is a single-direction axial bearing designed to support very high axial loads while maintaining excellent operational precision. Its cylindrical rollers and a reinforced polymer cage (TV) ensure stable rotation, high load capacity and long service life in heavy-duty industrial environments.

Key Features & Benefits

High load capacity, durability and stable shaft support

• Designed for significant axial loads in one direction, ideal for high-pressure drive assemblies and industrial mechanisms.

• Cylindrical roller design distributes load over a larger surface area, reducing wear and extending bearing life.

• Polyamide cage (TV) provides low friction, high precision and reliable performance under dynamic stress.

• Compact dimensions 40x68x19 mm allow easy integration into standard assemblies without modifications.

• Excellent resistance to vibration and mechanical stress, suitable for continuous heavy-load operation.

Main Description

The 81208-TV INA thrust cylindrical roller bearing is engineered for machinery requiring strong and stable axial support. Its construction with cylindrical roller elements distributes load efficiently, enabling operation under high axial forces without performance loss. This makes it an excellent solution for demanding applications such as power transmission systems, presses, hydraulic actuators, gearboxes, pump systems and heavy rotating machinery.

Compared to thrust ball bearings, the cylindrical roller design offers significantly higher load capacity and improved resistance to shock and vibration. The polyamide cage ensures smooth motion, low friction and thermal stability, supporting long maintenance intervals and continuous operation in industrial environments.

The standardized dimensions 40x68x19 mm ensure compatibility with common bearing housings and shaft designs, enabling fast installation, replacement and servicing — an important advantage for maintenance departments and manufacturers aiming to minimize production downtime.

If you need a robust, precise and high-capacity axial bearing for industrial machinery, 81208-TV INA is a reliable and efficient choice.
