When an assembly has to carry a heavy axial load in a single direction and there is little room in the radial direction, a cylindrical roller thrust bearing is often the answer. The rolling elements are cylindrical, and the washers are flat, which suits supports that need rigidity under thrust. MR Industrial Accessories LLC supplies the INA line to customers throughout the United States and in several Latin American countries.

Reading the designation is straightforward. The basic number tells you the series and the size, and the -M suffix identifies a machined brass cage that guides the rollers precisely and adds strength. Within a series, a higher number means a larger bearing. Before you look up a part number, have the mounting dimensions and the direction of the axial load ready.

Typical installations include presses, extruders, cranes, rotary tables, vertical-shaft gearboxes, high-flow pumps and material handling equipment, as well as steel mills, cement plants, food plants, mining operations and machine tools. What these have in common is a dominant thrust load in one direction, limited radial space and a need for a rigid support.

Selection starts with confirming that the axial load runs in one direction and that the support washers are hard enough and flat enough. The shaft and the housing must be aligned precisely, because this bearing type does not absorb angular misalignment. Lubrication should be clean and plentiful, with high-viscosity oil or grease in critical duty. Protecting the assembly from contaminants matters, since contamination is the leading cause of failure. If you would like help, send us the drawing or the dimensions.

Because cylindrical roller thrust bearings are made to dimensional standards, they can be interchanged between brands. For a quote, the complete part number including the -M suffix is the safest reference, together with the mounting dimensions if you have them. MR Industrial Accessories LLC supplies INA as part of its bearing range and can suggest equivalent options. Nomenclature differs from one maker to another, so confirm the exact part number before you replace a bearing.

If you already know the part number you need, send it to MR Industrial Accessories LLC by WhatsApp or email and the team will reply promptly. A photo of the part or its main dimensions works too. We can also help you choose the right component for the equipment.
