Chainsaw Piston Pin Needle Bearings

MARATO supplies piston pin needle roller bearings for chainsaw engines, brush cutters and other small gasoline engine applications. These bearings are installed between the piston pin and connecting rod to support oscillating loads and reduce friction during engine operation.

Multiple bearing sizes are available for selected Husqvarna, STIHL, Komatsu and compatible aftermarket chainsaw models. Because the same chainsaw model may use different bearing specifications depending on the production year and engine version, buyers should confirm the bearing dimensions before ordering.

How to Select the Correct Bearing

Please provide the following information so that we can check compatibility:

Chainsaw brand and complete model number
Original bearing code, if available
Inner diameter, outer diameter and width
Piston pin diameter
Photo of the original bearing
Required quantity and packaging requirements

Compatibility depends on the actual bearing dimensions, engine version and installation position. Model references are provided for identification purposes and do not mean that every bearing size fits every listed model.

MARATO supplies replacement needle bearings to importers, wholesalers, repair shops, parts distributors and equipment manufacturers. Samples, mixed-size orders and wholesale quantities are available.
