Hydraulic EasyPull
Quick and effortless bearing dismounting
The hydraulic versions of the EasyPull, TMMA 75H and TMMA 100H,
combine the user friendliness of the mechanical EasyPull with the effortless
force generation provided by integrated hydraulic spindles. The pullers are
protected from overload by safety valves built in their hydraulic spindles.
- Ready-to-use, integrated hydraulic cylinder, pump and puller - thus it is
assembly-free and it is not necessary to purchase separate parts
- Safety valve prevents spindles and pullers from being overloaded if excessive force is applied
- The spring-loaded centre point on the hydraulic spindle allows easy centring of the puller on the shaft without damaging the shaft
- The TMMA 100H has a maximum withdrawal force of 100 kN (11.2 ton US)
and a long stroke of 80 mm (3.1 in), which facilitates most dismounting jobs in just one operation
- For dismounting jobs requiring less force, SKF offers a 75 kN (8.4 ton US) version, the Hydraulic EasyPull TMMA 75H with a maximum stroke of 75 mm (3 in)
- Supplied with extension pieces and one nosepiece

Application:
- For extracting complete rolling bearings or tightly fitted inner rings
- Good radial and axial accessibility of the bearing location, possibly slots, required
- Big extractors (spans 390 and 640 mm) can be equipped with a hydraulic spindle (suffix H).
Operation:
Depending on bearing size and mounting conditions, the extractor with the suitable dimensions is selected. The span can be adjusted by shifting the lever system on the cylinder. During the extraction process the lever system causes self-locking of the arms and ensures a good grip. Rolling bearing rings that are extracted correctly remain undamaged.
Complete bearings where the extraction force is transmitted through the rolling elements usually become unserviceable.

The hydraulic FAG extractors PowerPull SPIDER are used where higher extraction forces are required. The ten extractor sizes have a range of extraction forces from 40 to 400 kN, covering very wide range of possible applications. These devices allow rolling bearings, gears, sleeves and many other shrink fitted parts to be quickly and easily dismounted. In addition, the low mass of the extractors allows for use in any position. If necessary, greater grip depth can be achieved through the use of extra long extraction arms (available as accessories). For protection of operators, the extractors SPIDER40 to 80 have a safety grid. All larger hydraulic extractors are supplied with a transparent, very tough safety cover. The cover can be easily placed around the workpiece or tool and secured using velcro strips.
