Important: design differences by model and production year
Bushing designs vary by brand and model, and even by the production year of the same model and by whether the breaker is a silenced (box type) or tunnel type unit. Two breakers with the same model name can use bushings of different size and shape.
If you send the technical drawing of your part to sales@hkm.com.tr, we can manufacture it to your drawing.
FEATURES
- High surface hardness (heat treated)
- Precise geometry that distributes axial loads
- Durability that protects the retaining pin area
- Made to OEM dimensions
- Produced to withstand axial load with hardness and geometry control
WHAT DOES A THRUST BUSHING DO?
It absorbs the tool's recoil and axial loads and distributes the load over the retaining pin area and the body to reduce wear. High surface hardness and accurate geometry safely carry the loads around the retaining pin area.
Other names used for this part include thrust ring, impact ring and thrust bush.
INSTALLATION AND MAINTENANCE NOTES
- Avoid blank firing; it damages the thrust bushing and the diaphragm.
- At every service check, evaluate the thrust bushing together with the retaining pin area.
- The lower bushing and the thrust bushing work together; when one reaches its wear limit, check the other as well.

Frequently Asked Questions
Q: What is the OEM part number of this part?
A: OEM part number: F45-20105. You can compare it with the number in your breaker's parts catalog or on the removed part. If your number is different, contact us and we will check for an equivalent.
Q: Does this thrust bushing fit my Furukawa F45 breaker?
A: It is manufactured for the Furukawa F45. The same model may have been built with different designs in different production years or housing types, so please compare the outer diameter and length with your existing bushing and check the OEM part number (F45-20105) against your breaker's parts catalog before ordering.
Q: When should the thrust bushing be checked?
A: At every service check. Blank firing sends the impact energy back into the body and the bushings, and the thrust bushing and diaphragm are among the parts it damages.
Q: What other names are used for the thrust bushing?
A: Other names used for this part include thrust ring, impact ring and thrust bush. For Furukawa breakers this part is also listed as "thrust ring".
Q: What if the part in my breaker does not match these dimensions?
A: Send the dimensions or the technical drawing of your current part to sales@hkm.com.tr. We will identify the right part with you and, if needed, manufacture it to your drawing.
Q: Is shipping included in the price?
A: No, shipping is not included in our prices. Please contact our sales team for the best delivery option to your location.
