Puller Plate for 3-Claw Puller TMMS

Specifications

How to choose Puller accessories

Points to check when selecting, with the values for this product (Puller Plate for 3-Claw Puller TMMS).

1. 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. 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. 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. 4. Select the Size for Shaft Diameter and Outer Diameter

   This product: Compatible Shaft Diameter 50–380 mm

   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. 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. 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.

About Puller accessories and all products

Description

Three-segment structure distributes the extraction force evenly, preventing tilting and locking of spherical roller bearings and similar bearings.

FAQ

Q. Which bearings can the TMMS series puller plate be used to remove?

A. It is used to remove spherical roller bearings and CARB toroidal roller bearings. Used with a 3-claw puller, it grips the back face of the bearing inner ring and pulls it out.

Q. Which shaft sizes does the TMMS puller plate cover?

A. Applicable shaft diameters are 50–380 mm. It is available in 5 sizes.

Q. Does the TMMS puller plate prevent tilting and locking during extraction?

A. The three-segment structure distributes the extraction force evenly, preventing tilting and locking of spherical roller bearings and similar bearings. Extraction force is transmitted only to the inner ring.

Q. How is the TMMS puller plate installed on the bearing shoulder?

A. Its wedge shape allows the plate to be inserted between the shoulders.
