Shaft & Bearing Kit for 4035HS

This information includes the number of mounting holes, their respective thread size, and the bolt circle on which the holes are placed — shown as the number in brackets.

Example 1: "4x M4(30)"
This means that the motor features four M4 mounting holes, placed on a 30 mm bolt circle.

For extended compatibility with a wide range of models, some of our motors feature a combination of different mounting hole sizes and/or bolt circles. In this case, the information is shown as follows:

Example 2: "2x M4(30) + 2x M3(25)"
This means that the motor features two M4 mounting holes placed on a 30 mm bolt circle, and two M3 mounting holes placed on a 25 mm bolt circle.

Don’t worry if only two of the mounting holes, opposite to each other, line up with your mounting bracket or motor plate. Using only two screws is perfectly fine — but as with any metal thread, always use threadlocker.
