To remove grooved ball bearings manufacturers efficiently from shafts and cases without dismounting the suppliers of bearing. This ideal tool assortment is suitable for bearing sizes from 10 to 100 mm bore diameter.
6 puller arm sets and 2 threaded spindles in a practical case
Puller arm with a joint in order to guarantee an optimal power transmission on the bearing
User-friendly because of the elastic retaining ring which keeps the puller arms in position
Puller arm made from quality steel
The EasyPull, TMMA 8E, combines the user friendliness and safety of the mechanical EasyPull with the effortless force generation by an integrated hydraulic suppliers of spindle. The TMMA 8E has a maximum withdrawal force of 80 kN (8 tons imp). The puller is protected from overload by a safety tap built in the hydraulic spindle.
- Ready-to-use, integrated supplier of hydraulic cylinder, pump and puller - separate hydraulic spindle and pump are not required
- The unique red rings spring-operated opening mechanism allows the puller to be placed behind the component with one movement of the hands
- Self-locking arms facilitate firm grip behind the component, minimising the risk of the puller slipping while under load
- The long stroke of 80 mm (3.1 in) facilitates dismounting in one operation
- Safety cock prevents spindle and thereby puller overload 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 it
- For dismounting jobs requiring less force, SKF offers a 50 kN (5 tons imperial) version; Hydraulic EasyPull TMMA 5E with a maximum stroke of 75 mm (3 in).
Application:
- For extracting complete rolling suppliers of 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 manufacturers (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.
MECHANICAL, HYDRAULIC & HYDRAULIC SELF-CENTERING PULLERS
Capacity 5 Tons to 60 Tons, Two/Three Arms, Reach 225mm to 727mm, Spread 60mm to 920mm in various models, Full Hydraulic Puller Sets, Master Pullet Sets, Grip Pullers sets also available
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 professional 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 fume extraction (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.
