Puller Kit for Deep Groove Ball Bearings TMMD 100

Specifications

How to choose Puller

Points to check when selecting, with the values for this product (TMMD 100).

1. 1. Allow margin in the required pulling force

   Larger interference fits and larger parts require more force. The listed maximum pulling forces range from 6 to 500 kN, and hydraulic types are mainly used at around 100 kN and above. Also check whether a safety valve is provided to prevent overloading.

2. 2. Confirm the outer diameter falls within the grip width

   The outer diameter of the bearing or part to be removed must fall within the outer diameter range the claws can grip. Claw engagement tends to be shallow at the ends of the range, so select a model with some margin. When used as an internal puller, check the inner-diameter grip width.

3. 3. Confirm the claws reach the back of the part

   This product: Effective Arm Length 135–170 mm

   If the effective arm length is insufficient for the part thickness or its position from the shaft end, the claws will not engage the back face. For bearings far from the shaft end, models supplied with extension rods or extension pieces, or models with a large maximum reach from the shaft end, are suitable.

4. 4. Match the bearing bore and shaft diameter

   This product: Applicable bearing bore diameter 10–100 mm

   Back-face pullers and inner race pullers have defined applicable ranges for bearing bore and shaft diameter. Listed products cover bearing bores from 7 to 160 mm. Check the bore, outer diameter and width of the target bearing from its model number against the applicable range.

5. 5. Check the pulling travel and stroke

   Fully removing a bearing from the shaft requires travel equal to the fitted length. If the maximum stroke is insufficient, extension pieces must be added partway through the work, so select a model by comparing its stroke with the fitted length.

6. 6. Select the type to suit the mounting condition

   Inner race or forcing-type pullers suit cases where the outer ring is press-fitted into a housing. Back-face or collet-type pullers suit cases where there is little clearance behind the inner race. Jaw pullers suit cases where the outer circumference can be gripped. The suitable type therefore depends on the mounting condition.
