The SKF TMHN wrench set is a specialized tool for tightening and loosening the lock nuts that hold self-aligning bearings on a shaft. It is used when mounting, removing or replacing bearings, especially where space is tight and the nut must be engaged precisely without damage. MR Industrial Accessories supplies this SKF tool line to workshops, plants and maintenance teams.
Each set is identified by the letters TMHN followed by a number that corresponds to the size or range of lock nuts it fits. For instance, TMHN 7 is intended for a specific nut diameter. That number is not random; it tells you which nut the wrench was built to handle. When you request a quote, include the complete part number marked on the nut or bearing so we can point you to the correct set.
These wrenches are made for mounting and dismounting self-aligning bearings, which use lock nuts with slots or notches. They appear in food processing, cement, mining, paper and maintenance shops that service rotating equipment such as pumps, fans, conveyors, mills and mixers. Having the proper wrench on hand helps prevent impact damage and deformation of the nut during bearing replacement.
To select the right set, start by identifying the self-aligning bearing and its lock nut. The nut part number determines which TMHN wrench you need. Never force a wrench that does not seat perfectly, as this rounds the nut faces. When mounting, place the wrench on a properly seated nut and turn it smoothly. If the nut binds, inspect the threads for damage. Lubricating the thread before tightening helps achieve uniform torque.
SKF TMHN wrenches are made for self-aligning bearing nuts from the same brand, but they can also work on equivalent nuts from other manufacturers if the dimensions and notch profile match. There is no universal interchangeability chart; compatibility is confirmed by measuring the nut diameter, pitch and shape. If you are unsure, send us the nut and bearing part numbers and we will guide you.
If you need an SKF TMHN wrench set for your maintenance work, contact us via WhatsApp with the nut or bearing part number. At MR Industrial Accessories we help you request the correct tool and avoid damaging components during mounting. We can also quote other SKF mounting and maintenance tools.

Frequently asked questions
- What type of nuts does the SKF TMHN set fit?
- It fits lock nuts for self-aligning bearings, which have slots or notches around the edge. It is not a general-purpose wrench. If your nut has a different shape, send us the part number and we will check for an alternative.
- How do I determine which TMHN number I need?
- The set number relates to the nut size. The most reliable method is to provide the part number of the lock nut or the self-aligning bearing you plan to mount. With that information we will identify the matching TMHN. Do not select based only on shaft diameter.
- Can I use the TMHN wrench on nuts from other brands?
- It may fit if the nut has the same dimensions and notch type, but there is no automatic cross-reference between brands. Verification is done by measuring. If you give us the nut measurements, we will confirm whether the TMHN set works or if another option is better.
