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.

- Check the tool's lateral play regularly; increasing play is the first sign of bushing wear.
- If the play exceeds the wear limit in your manual, replace the bushing and the seal kit together; replacing only the seal is a temporary fix.

Frequently Asked Questions
Q: What is the OEM part number of this part?
A: OEM part number: 3315 2779 80. 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 combined bushing fit my Atlas Copco SBC410IIS breaker?
A: It is manufactured for the Atlas Copco SBC410IIS. 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 (3315 2779 80) against your breaker's parts catalog before ordering.
Q: Which bushings does a combined bushing consist of?
A: A combined bushing is a single piece that combines the upper bushing and the lower bushing in one body, so you do not need to order these two bushings separately. Compare the dimensions with your existing part.
Q: When should the combined bushing be replaced?
A: When the tool's lateral play exceeds the wear limit in your breaker's manual. If the breaker leaks oil at the tool end, measure the play first: above the limit, replace the bushing and the seal kit together; below the limit, replacing only the seal kit is enough. The limit depends on the model, so check your manual or send us the model code.
Q: What other names are used for the combined bushing?
A: Other names used for this part include combine bushing.
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.
