89317 -M INA cylindrical roller thrust bearing

INA 89317-M Cylindrical Roller Thrust Bearing (Reinforced Series)

The INA 89317-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 axial solutions. The standout feature of this model is the solid brass cage (M). It provides superior roller guidance, effectively dampens vibrations, and ensures operational stability at elevated temperatures. Thanks to the linear contact of the rolling elements, this model offers the maximum axial rigidity required for high-precision heavy machinery.

Application

• Heavy Machinery: Axial support for spindles in large machine tools, hydraulic 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 heavy mining equipment.
• Logistics: Lifting mechanisms and high-tonnage conveyor systems.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: 89317-M.
• Dimensions: 85 mm (ID) × 150 mm (OD) × 39 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 load, guaranteeing operational precision.
• Durable Brass Cage (M): Reduced risk of seizure and better performance under boundary lubrication compared to steel or polyamide cages.
• High Load Capacity: Designed to handle much greater forces than the 812 series with the same bore size.
• Ease of Maintenance: The separable design allows for independent replacement of washers or the assembly, lowering long-term costs.
• SCHAEFFLER Quality: The use of high-purity metallurgical steel significantly extends the bearing's fatigue life.

Why Choose This Product

By choosing the INA 89317-M bearing, you are investing in a premium product from a global leader in rolling technology. In 85 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.
