SKF TIH heater: how to choose between TIH 030M, TIH 100M and TIH 220M

An SKF TIH heater is an electromagnetic induction device that heats the bearing to expand its bore and mount it on the shaft without effort. It is used in industrial maintenance when the fit is interference and the bearing does not go on cold. Induction heating is even and controlled, unlike a torch or an oil bath.

The SKF TIH series is designed for workshops and plants that mount bearings frequently. The operator places the bearing on the device's yoke, selects the temperature and the device heats it evenly. Then the hot bearing is placed on the shaft and left to cool so it stays firm.

At MR we market and distribute these devices for rotating machine maintenance: electric motors, pumps, gearboxes, fans and compressors. If you are about to mount a bearing with a force fit, an induction heater saves you from impact damage and contamination.

The three models share the induction principle, but the working capacity changes. The TIH 030M/230V is the most compact of the three and is used for small and medium bearings in light maintenance workshops. The TIH 100M/230V increases capacity for plants that mount larger bearings.

The TIH 220M/LV and the TIH 220M/MV are the largest in this series. They are chosen when the largest bearing you mount in the plant is heavy or has a significant bore. What comes after the slash indicates the supply voltage variant: /LV and /MV are two different variants, and which one applies is confirmed with the plant's panel.

To choose, look at the largest and heaviest bearing you routinely mount. The heater must be comfortable for that job, not just barely enough. If the device falls short, the bearing does not reach the required temperature or the cycle becomes very long. At MR we help you define the model according to your case.

TIH heaters are manufactured with different supply voltages and that is indicated at the end of the code. For example, TIH 030M/230V and TIH 100M/230V are the /230V variants. The TIH 220M/LV and TIH 220M/MV models are two voltage variants of the same model.

Before requesting a quote, confirm with your plant's panel what voltage you have available. Ordering the wrong model can leave you with a device you cannot connect. If in doubt, send us a photo of the panel's nameplate or the electrical specification.

The TIH 15/230V is another model in the TIH series. If you are interested, send us the code of the largest bearing you mount and we will confirm whether it works for you or whether a TIH 030M, TIH 100M or TIH 220M is better. That way you avoid a device that falls short for your routine work.

The TIH series has accessories that are ordered separately depending on the heater model. The TIH P20 is the temperature probe and the TIH RC is the heater's remote control; TIH T1 is another spare part in the series. They are not heaters themselves, but complements for the device.

Not all accessories work with all models. It is not advisable to order them without knowing which heater you have, because they may not be compatible. With your device model we indicate which one applies.

When ordering an accessory, mention the full heater model, for example TIH 100M/230V. That way we avoid confusion and quote you the correct part. You can also send a photo of the device or the label.

To quote you an SKF TIH heater, we need three data points: the model, the voltage variant and the largest bearing you mount. With that we indicate whether the device you are requesting is suitable or whether another in the series is better.

The largest bearing is identified by the code engraved on the ring, for example 6312 or 22220. If you do not have the code, measure the bore, the outer diameter and the width. With those measurements we can estimate the size of the heater you need.

A photo of the bearing or of the equipment where it is mounted also helps. The more information you send us, the more accurate the recommendation will be. Write to us via WhatsApp or email and we will reply promptly.

The most frequent mistake is choosing a small heater to save money. If the bearing is too large or heavy for the device, heating is slow and may not reach the mounting temperature. A bearing that did not expand enough gets stuck on the shaft halfway.

Another mistake is not verifying the supply voltage. A device ordered for one voltage cannot be connected to another. Always confirm the voltage before ordering, and if in doubt, consult us with the panel's nameplate.

Mistakes are also made when using the heater: overheating, not using thermal gloves or not measuring the temperature. The device has temperature control, but it must be configured according to the bearing. Follow the manufacturer's instructions and use the correct accessories.

At MR we market and distribute SKF induction heaters from the TIH series. We work with the TIH 030M/230V, TIH 100M/230V, TIH 220M/LV, TIH 220M/MV and TIH 15/230V models, as well as accessories such as TIH T1, TIH P20 and TIH RC.

To get a quote, send us via WhatsApp or email the full model, the voltage variant and the largest bearing you mount. If you do not know the model, tell us what equipment you maintain and we will guide you. You can also send a photo of the bearing or the work area.
