SKF bearing pullers: mechanical, reversible and hydraulic

Hammering a bearing off damages the shaft, the housing and sometimes the person holding the hammer. A puller applies the force where it belongs, and evenly. At MR Accesorios Industriales we sell SKF jaw pullers, reversible pullers, hydraulic pullers, strong back pullers and blind housing pullers, as well as Crossmaster universal pullers. Every part number in our catalog is listed below, grouped by series.

What a bearing puller is for

A bearing mounted with an interference fit will not come off by pulling just anywhere. The rule is simple: the withdrawal force goes on the ring that has the fit. If the bearing is tight on the shaft, pull the inner ring; if it is tight in the housing, pull the outer ring. When the force passes through the balls or rollers, the raceways are marked and the bearing cannot be used again.

That is why there is more than one type of puller. Jaw pullers grip the part from the outside. Strong back pullers are used where there is no room for jaws: a two-piece separator plate closes behind the bearing. Internal pullers and blind housing pullers remove bearings from a housing with no access from behind. Choosing the right type is half the job.

How to choose a puller

Four questions settle the choice. First: where do you have to pull from? If you can reach behind the ring, a jaw puller does the job; if there is no room, you need a strong back puller; if the bearing sits inside a housing, an internal or blind housing puller. Second: how big is the part? The puller must open wider than the outside diameter of the bearing and its arms must reach behind it; the numbers in each designation rank the series by size.

Third: how much force is needed? A mechanical puller is enough for small and medium bearings. When the bearing is large or seized, a hydraulic puller is the better choice: a pump or hydraulic spindle generates the force and leaves your hands free to hold and center. Fourth: two jaws or three? Three center better and spread the load; two are for places where there is no room for the third. Reversible pullers work from the outside or the inside with the same tool.

With the bearing part number (or its outside diameter and width), the shaft diameter and a photo of how it is mounted, we will tell you which puller fits.

Safety when pulling

Center the spindle on the shaft and check that the jaws grip evenly before applying force. Do not use extensions on the wrench and do not hit the puller to help it along: if the part does not move, you need a puller with more capacity or a hydraulic one. Wear safety glasses and, with large pullers, use a protection blanket such as the TMMX, which wraps the work area during the pull.

TMIP series: internal bearing pullers · 7 part numbers

Internal puller kits for bearings seated in a housing: they expand inside the bearing bore and draw it out. In TMIP 7-28 and TMIP 30-60 the number in the code indicates the range of bores the kit covers.

Frequently asked questions

Which puller do I need to remove a bearing from a shaft?

If you can grip the inner ring from behind, a jaw puller (TMMA, TMMP or TMMR series). If the bearing sits against a shoulder and there is no room for the jaws, a strong back puller (TMBS series). The size comes from the outside diameter of the bearing and the depth at which it is mounted.

When is a hydraulic puller the better choice?

When the bearing is large, has been mounted for a long time, or a mechanical puller demands too much effort. Hydraulic actuation applies the force evenly and with less effort from the operator. The catalog lists the TMHP pullers, the TMMA 75H and TMMA 100H, and the TMHC 110E kit.

Two-jaw or three-jaw puller?

Three jaws whenever space allows: they center better and spread the load. A two-jaw puller is used when there is no room around the part for the third jaw.

How do you remove a bearing from a blind housing?

With a puller that works from the front: an internal puller (TMIP series), which expands inside the bearing bore, or a blind housing puller such as the TMBP 20E. Tell us the bearing part number and how it is mounted and we will point you to the right one.

Can a bearing be reused after it has been pulled?

Only if the force was applied to the ring with the fit and the bearing was not marked. If it was pulled through the balls or rollers, the correct thing is to replace it.

Do you carry arms and spare parts for SKF pullers?

We sell them: many of the part numbers in the list are arms, spindles and spares for each series. Send us the spare part number or the puller model and check availability.
