K89314 -TV INA cylindrical longitudinal assembly

INA K89314-TV Cylindrical Roller and Cage Thrust Assembly (Reinforced Series)

The K89314-TV INA assembly is a critical axial bearing component consisting of precision cylindrical rollers secured in a high-strength cage. Part of the 893 series, it is designed to handle extreme axial loads with a very low cross-sectional height. At its core is a glass-fiber reinforced polyamide 66 cage (TV), ensuring quiet operation, weight reduction, and superior lubrication properties. Thanks to the linear contact of the rollers, the K89314-TV provides uncompromising axial rigidity for the most demanding mechanical arrangements.

Application

• Machine Engineering: Precision support for machine tool spindles and high-pressure screw actuators.
• Automotive: Gearboxes and power transmission systems in heavy-duty vehicles and agricultural machinery.
• Automation: Rotary tables and positioners requiring high rigidity in limited axial space.
• Energy Sector: Vertical shaft support in industrial pumps and generators.
• Heavy Equipment: Presses and conveyor systems subjected to significant longitudinal forces.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: K89314-TV.
• Dimensions: 70 mm (ID) × 125 mm (OD) × 14 mm (Assembly height).
• Cage Type: TV – Glass-fiber reinforced Polyamide 66.
• Series: 893 (Heavy Duty – enhanced load capacity compared to 811/812 series).
• Compatibility: Works with shaft washers WS89314 and housing washers GS89314.

Features and Benefits

• Enhanced Load Capacity: The 893 series design allows for higher axial force handling than standard assemblies.
• Lightweight TV Cage: Polyamide minimizes friction, reduces heat generation, and prevents premature lubricant degradation.
• Compact Design: A height of only 14 mm enables the construction of extremely rigid systems in tight spaces.
• Modularity: Allows for the replacement of the cage assembly independently of the washers, lowering maintenance costs.
• SCHAEFFLER Quality: Guaranteed highest manufacturing precision and extended fatigue life.
