Compressor with Oldham assembly

A compressor comprising:

• a non-orbiting scroll;
• an orbiting scroll meshingly engaged with the non-orbiting scroll;
• a driveshaft having a crankpin engaging the orbiting scroll and driving the orbiting scroll in an orbital path relative to the non-orbiting scroll;
• and
• an Oldham coupling including an annular body and a plurality of first keys extending from the annular body and slidably received in first slots formed in the orbiting scroll, each of the first keys including a first post and a first cap covering at least a portion of the first post, the first posts are integrally formed with the annular body from a first material, the first caps are attached to the first posts and formed from a second material,
• wherein each of the first caps includes an aperture and a pair of grooves, the aperture receiving a corresponding one of the first posts,
• wherein deformations are formed on the first posts such that the deformations are forced into the grooves to fix the first caps to the first posts, and
• wherein the grooves are open to the aperture and extend through a distal end of the first cap.
