Puller accessories
Puller accessories are components that combine with pullers used to extract bearings, gears, pulleys and similar parts from shafts, adding capacity, application range and safety. Main types include hydraulic spindles that replace the manual mechanical spindle, pulling plates that work with three-jaw pullers to grip the back of the bearing inner ring, and protective covers that prevent parts from flying during operation. Hydraulic spindles integrate the cylinder and pump, so a large pulling force can be obtained by handle operation alone without an external pump. They are used for removing tight-fit bearings and large components, and for maintenance work where only the inner ring should be pulled without applying force to the outer ring.

How to choose Puller accessories
-
1. Meet the Required Pulling Force
The greater the interference fit and the size of the component, the greater the force needed to pull it out. The listed hydraulic spindles have a maximum pulling force of 75 to 100 kN. Also check the allowable load of the puller body it will be combined with, and select so that the lower of the accessory and puller values is not exceeded.
-
2. Check Stroke and Extension Length
The stroke is the distance that can be pushed in one operation, and the listed models have 75 to 80 mm. If the pulling distance is longer, add extension pieces and check whether it falls within the maximum extension length (229 to 390 mm). Verify by comparing the distance from the shaft end to the component.
-
3. Confirm Body Thread Compatibility
The hydraulic spindle is used by screwing it into the spindle thread of the puller body. If the thread nominal size or pitch does not match, it cannot be installed, so compare the thread standard of the puller in use with the body thread of the accessory.
-
4. Select the Size for Shaft Diameter and Outer Diameter
Pulling plates have a usable shaft diameter range defined for each size, and a size must be chosen that reliably engages the back of the inner ring. Also check the recommended maximum diameter and confirm that the outer diameter of the part being pulled falls within that range.
-
5. Structure That Applies Force to the Inner Ring Only
Gripping the outer ring side of spherical roller bearings and similar types can damage the rolling elements or raceways. A wedge-shaped plate type that grips the back of the inner ring transmits the pulling force only to the inner ring. Consider this structure especially when the bearing will be reused.
-
6. Overload Prevention and Flying Debris Countermeasures
Under high loads, parts may suddenly release or the puller may detach and fly. Hydraulic spindles with a safety valve prevent overload, and a configuration with a transparent resin protective cover that prevents flying while allowing the work to be observed improves safety.
