The cylindrical roller thrust bearing is a component designed to withstand high axial loads in a single direction. Its cylindrical roller geometry and flat washers allow it to work with high rigidity and load capacity in applications where other thrust bearings do not perform. MR Accesorios Industriales supplies the INA line in Buenos Aires, Argentina, with more than 80 years of experience in the industrial sector.

The designation of these cylindrical roller thrust bearings is read from their base number and the suffix -M. The base number, as in the examples 81136-M, 81138-M or 81140-M, identifies the series and size; the suffix -M indicates a machined brass cage, which provides strength and precise roller guidance. In the 811 series, increasing numbers correspond to larger dimensions. To choose the correct part number, have the mounting dimensions and the direction of the axial load at hand.

These bearings are used in applications with significant axial loads and little radial space: presses, extruders, cranes, rotary tables, vertical shaft gearboxes, high-flow pumps and material handling equipment. In Argentine industry they appear in steel mills, cement plants, food plants, mining and machine tools. Their ability to withstand strong thrust in a single direction makes them suitable for assemblies where the axial load is dominant and rigidity is required.

To select correctly, verify that the axial load acts in a single direction and that the support washers have adequate hardness and flatness. Mounting requires precise alignment between shaft and housing, since these bearings do not compensate for angular misalignment. Lubrication must be abundant and clean; in critical applications, high-viscosity oil or grease is recommended. Sealing the assembly protects against contaminants, which are the main cause of failure. If you need guidance, consult us with the drawing or dimensions.

Cylindrical roller thrust bearings are manufactured under dimensional standards that allow interchangeability between brands. When requesting a quote, the safest approach is to indicate the complete part number with the -M suffix and, if possible, the mounting dimensions. MR Accesorios Industriales supplies the INA brand as part of its bearing line, and can offer equivalent alternatives subject to availability. Not all brands use the same nomenclature, so it is advisable to verify the exact part number before replacing.

If you already have the part number of the thrust bearing you need, send it via WhatsApp to MR Accesorios Industriales and we will quote you shortly. You can also send us a photo of the part or the main dimensions. With more than 80 years in the market, at MR Accesorios Industriales we help you find the right component for your equipment.
