This 20 kg barbell is made of spring steel with a black zinc-plated surface coating to prevent rust. This Olympic barbell has a tensile strength of 230,000 PSI and a yield strength of 199,000 PSI, so you can clean, snatch and deadlift safely and securely. Knurl The knurling on this barbell is designed for a smooth knurling depth-neither too tight nor without grip Bushes and bearings The needle bearing housing in the collar provides more rotation than the bushed barbell. The rotation of the bearing barbell is slightly smoother and slightly more expensive than the bushing. Bearing barbells are usually used for faster lifts, such as Olympic lifts. Bushed barbells are usually used for heavier or slower lifts, such as power lifts. Custom Logo We have 12 years of experience in manufacturing and marketing all kinds of small fitness equipment.
