Strong back pullers
Easy bearing dismounting even in the tightest spaces

The SKF TMBS E strong back pullers facilitate dismounting of bearings in applications where the use of traditional jaw pullers is restricted due to lack of space or where the application demands a long reach. TMBS 100E and the TMBS 150E bearing extractors are equipped with a hydraulic spindle, which allows for effortless application of force up to 100 kN (11.2 ton US). The TMBS 50E is equipped with a mechanical spindle for force generation.

- Special bearing separator design allows the puller to be easily inserted between the bearing and the shoulder on the shaft, even in the tightest spaces
- The firm grip behind the bearing's inner ring reduces the force required to dismount the bearing
- High load rating of 100 kN (11.2 ton US) make the TMBS 100E and TMBS 150E suitable for use in many applications
- TMBS 100E and TMBS 150E offer complete hydraulic puller kits, allowing effortless generation of force
- The extension rods of the TMBS 100E and TMBS 150E allow easy and quick adaptation to required pulling length
- Maximum reach of 825 mm (32.5 in) and maximum shaft diameter of 150 mm (6 in) allow the TMBS E series to be used in many applications
- The hydraulic spindle is equipped with a safety valve, which limits the applied force to 100 kN (11.2 ton US), minimising the risk of puller overload
- The spring-loaded centre point of the hydraulic spindle allows easy centring of the puller on the shaft without damaging it
- Long stroke of hydraulic spindle, 80 mm (3.1 in), facilitates dismounting in one operation
- Pumping mechanism used for force generation is effortless and more efficient than turning mechanism
- Extension pieces of the hydraulic spindle allow quick adaptation to pulling length
