Please refer to the table below for bearings to fit the OS range of  2 stroke Aeroplane engines.

When replacing engine bearings, we recommend both front and rear bearings are replaced together. Unless stated otherwise, 1 front and 1 rear bearing is required per engine.

If you have an engine that is not listed, or the table states 'Bearing data required', please  go to the 'Bearing Enquiries' page to send us details - we will almost certainly be able to find you a replacement. We give a 10% discount on the normal bearing selling price when you have given us information which adds to our bearings data lists.

To order, click on the 'Add to Order' button alongside the item of your choice. You can select the quantity on the order form (default is 1). To continue ordering other items, use the 'Continue Shopping' button on the order form.

You can review and edit your order, or submit your order at any time by using the button at the bottom of each list.
