89320 -M INA cylindrical roller thrust bearing

INA 89320-M Cylindrical Roller Thrust Bearing (Reinforced Series)

The INA 89320-M is a high-performance rolling unit engineered to accommodate exceptionally heavy axial loads in a single direction. It belongs to the 893 series, which features a reinforced design and higher load ratings compared to standard solutions. The standout feature of this model is the solid brass cage (M). It provides superior roller guidance, effectively dampens vibrations, and exhibits high resistance to elevated temperatures and challenging lubrication conditions. Thanks to the linear contact of the rolling elements, this model offers the extreme axial rigidity required for high-precision heavy machinery.

Application

• Heavy Machinery: Axial support for spindles in large machine tools, presses, and extruders.
• Energy Sector: Vertical shaft bearings for generators and massive industrial pumps.
• Automation & Robotics: Large-scale rotary tables and positioners under significant axial pressure.
• Mining Industry: Drive components in drilling rigs and crushing equipment.
• Logistics: Lifting mechanisms and high-tonnage conveyor systems.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: 89320-M.
• Dimensions: 100 mm (ID) × 170 mm (OD) × 42 mm (Total height).
• Cage Type: M – Solid brass cage (roller-guided).
• Load Type: Unidirectional axial loads only (Heavy Duty).
• Design: Separable (allows independent mounting of washers and the roller assembly).

Features and Benefits

• Maximum Axial Rigidity: The 893 series geometry ensures minimal deflection under full load, guaranteeing operational precision.
• Durable Brass Cage (M): Reduced risk of seizure and better performance under boundary lubrication conditions compared to steel or polyamide cages.
• High Load Capacity: Designed to handle greater forces than the 812 series with the same bore size.
• Ease of Maintenance: The ability to replace individual components independently lowers long-term operational costs.
• SCHAEFFLER Quality: The use of high-purity metallurgical steel extends the bearing's fatigue life.

Why Choose This Product

By choosing the INA 89320-M bearing, you are investing in a premium product from a global leader in rolling technology. In 100 mm shaft applications where axial forces are extreme, the reinforced 893 series with a brass cage provides a safety margin that standard solutions cannot match. This is the foundation for your machinery's reliable operation, leading to fewer downtimes and higher production efficiency.
