81156 M

The 81156 M is a single row cylindrical roller thrust bearing specifically engineered to handle substantial axial loads and impact loads in one direction. This robust bearing, with notable dimensions typically around a 280mm bore diameter, 350mm outer diameter, and 53mm height, is a go-to solution where thrust ball bearings lack sufficient load-carrying capacity. The "M" designation often indicates a machined brass cage, known for its strength and suitability for higher speeds and temperatures. These bearings are designed for high stiffness and require minimal axial space, making them ideal for compact and demanding applications. It's important to note that they are not designed to accommodate radial loads.

A key characteristic of the 81156 M bearing is its separable design. The shaft washer, housing washer, and the cylindrical roller and cage thrust assembly can all be mounted independently. This feature greatly simplifies the mounting and dismounting process, as well as maintenance inspections, allowing for more efficient assembly and upkeep. The roller ends são normalmente aliviados ou perfilados para modificar o contato da linha entre os rolos e as pistas . Esse design ajuda a evitar picos de estresse, garantindo uma distribuição mais uniforme de carga e contribuindo para uma vida operacional prolongada para o rolamento, mesmo sob condições de carga pesada ou de choque .}

Primarily utilized in heavy engineering applications, the 81156 M cylindrical roller thrust bearing excels in environments requiring high axial load capacity and rigidity. Common applications include industrial transmissions, material handling equipment, machine tools (such as in press applications or heavy-duty spindles), steel rolling mills, and equipment in the mining and construction sectors. Their ability to manage significant As forças de impulso unidirecional as tornam um componente confiável para garantir a longevidade e o desempenho das máquinas operando sob condições graves .
