89422 -M INA cylindrical roller thrust bearing

INA 89422-M Cylindrical Roller Thrust Bearing (Heavy Duty Series)

The INA 89422-M is a heavy-duty rolling component engineered to handle extreme axial loads in a single direction. Part of the reinforced 894 series, it offers significantly higher rigidity and load capacity compared to standard 811 or 812 series. A key design feature is the solid brass cage (M), which is roller-guided. Brass provides natural self-lubricating properties, excellent vibration dampening, and superior heat dissipation—essential for critical bearing arrangements in heavy machinery.

Application

• Heavy Industry: Hydraulic presses, metal rolling mills, and high-compression extruders.
• Energy & Mining: Turbine main shafts, vertical generators, and rotary tables for drill rigs.
• Metalworking: Spindles for heavy vertical lathes and large-scale machining centers.
• Marine Engineering: Propeller shaft thrust blocks and steering gear mechanisms.
• Construction: Slewing bearings for tower cranes and heavy piling rigs.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: 89422-M.
• Dimensions: 110 mm (ID) x 190 mm (OD) x 48 mm (Height).
• Cage Type: M – Solid brass cage.
• Design: Separable (shaft washer, housing washer, and roller assembly).
• Load Rating: Heavy Duty – maximum resistance to axial pressure.

Features and Benefits

• Maximum Axial Rigidity: Linear roller contact ensures minimal deflection even under full load.
• Durable Brass Cage (M): Enhances bearing lifespan under boundary lubrication and high-temperature conditions.
• Running Precision: Manufactured to SCHAEFFLER’s premium standards, ensuring minimal axial run-out and quiet operation.
• Shock Resistance: The robust 894 series design effectively absorbs dynamic load changes.
• Easy Installation: Separable design allows for independent installation of components within the machine housing.

Why Choose This Product

By choosing the INA 89422-M bearing, you are investing in the highest level of reliability for your machinery. In applications with a 110 mm shaft, where axial forces reach hundreds of kilonewtons, there is no room for compromise. The 894 series with a brass cage provides the foundation for trouble-free operation, drastically reducing the risk of unplanned downtime and expensive major repairs.
