The SKF TMHN wrench set is a mounting and maintenance tool designed specifically to tighten and loosen the lock nuts that secure self-aligning bearings on their shaft. It is used in bearing mounting, dismounting and replacement tasks, where access is limited and a wrench that fits the nut precisely without damaging it is needed. MR Accesorios Industriales sells this SKF tool line for workshops, plants and industrial maintenance.

The designation of these sets is made up of the letters TMHN followed by a number that identifies the size or range of nuts it covers. For example, the TMHN 7 corresponds to a set for a certain nut diameter. The number is not an arbitrary code: it indicates the application for which the wrench was manufactured. When requesting a quote, it is advisable to provide the full part number shown on the nut or on the bearing to be worked on, so the correct set can be selected.

These are tools designed for the mounting and dismounting of self-aligning bearings, which have lock nuts with slots or notches. They are used in industries such as food, cement, mining, paper and in maintenance workshops that work with rotating equipment: pumps, fans, conveyor belts, mills, mixers. In Argentina, where bearing replacement is a frequent task, having the right wrench prevents impacts and deformation of the nut.

To choose the correct set, first identify the self-aligning bearing and its lock nut: the nut part number defines which TMHN wrench is needed. Do not force a wrench that does not fit perfectly, because the nut faces will be rounded. During mounting, apply the wrench to the properly seated nut and turn smoothly; if the nut is stuck, check for damaged threads. Lubricating the thread before tightening helps the torque to be uniform.

SKF TMHN wrenches are specific to self-aligning bearing nuts of the brand itself, but they can work for equivalent nuts from other brands if the dimensions and notch type match. There is no universal equivalence table: interchangeability is verified by measuring the diameter, pitch and shape of the nut. If you have doubts, ask us with the nut and bearing part numbers and we will guide you.
