Abstract
A method for manufacturing a roller, adapted to equip a mechanical system forming a cam follower or a rocker arm. The roller is centered on a central axis and comprising: an outer cylindrical surface adapted to roll on a cam, an inner cylindrical bore adapted to receive a pin belonging to the mechanical system, and two lateral faces extending radially to the central axis. The method includes a machining step forming circular grooves that are concentric with each other on at least one of the lateral faces of the roller. The roller can be installed within a mechanical system.

A method for manufacturing a roller, adapted to equip a mechanical system forming one of a cam follower or a rocker arm, the roller being centered on a central axis and comprising:
- an outer cylindrical surface adapted to roll on a cam;
- an inner cylindrical bore adapted to receive a pin belonging to the mechanical system;
- and
- two lateral faces extending radially to the central axis;
- the method including a step of forming circular grooves on at least one of the lateral faces of the roller using a machining process, wherein the circular grooves are concentric with each other.
A mechanical system, forming one of a cam follower or a rocker arm, the mechanical system comprising:
- at least one support element;
- a pin supported by the support element;
- and
- a roller centered on a central axis and comprising:
- an outer cylindrical surface adapted to roll on a cam,
- an inner cylindrical bore adapted to receive the pin, and
- two lateral faces extending radially to the central axis,
- wherein circular grooves are formed concentric with each other on at least one of the lateral faces of the roller.
