Parts of a Barbell: Learn the Lingo

Every barbell may look similar at first glance, but each is carefully designed. Here's a breakdown of standard barbell components:

• Shaft: The long, straight middle section you grip during lifts.

• Knurling: Textured areas etched into the shaft to improve grip.

• Knurl Marks: Smooth rings within the knurling that indicate hand placement; different in powerlifting vs. weightlifting bars.

• Sleeves: The rotating ends of the barbell where barbell weights (plates) are loaded.

• Collars: Rings separating the shaft from the sleeve; they help keep plates in place.

• Bearings/Bushings: Mechanisms in the sleeves that allow them to spin—important for Olympic lifts.
