Olympic Barbell Weight Bar for Weightlifting, Bench Press Bar 7ft-black. [MATERIAL] Olympic bar is made of high grade steel with excellent resistance to oxidation. The top of the barbell is chrome plated to prevent the bar from rusting and corrosion. The Olympic bar is equipped with needle bearings and brass bushings to make the sleeve turn very smoothly and almost noiseless. [SPECIFICATION]The length of Olympic barbell is 7ft/86.6in; the length of the sleeve is 16in, the diameter is 50mm, suitable for 2in diameter Olympic weights; the diameter of the grip part is 28mm, with 1.2mm scale medium knurling, can be well gripped, but will not tear your hand into pieces![APPLICATION]The barbell is the king of developing and growing muscles, and can hit multiple muscle groups at once; you can work each muscle group with compound movements such as squats, deadlifts, presses; and the barbell and weight plates don't take up space. [LOAD BEARING] Olympic bar has a weight capacity of 500lbs and a stretch strength of 190K is definitely feasible for most home gyms. A bushing rotation system will provide a smooth and consistent spin that will require little maintenance and should last for many decades.
[TIPS]The barbell may be a relatively low-maintenance piece of fitness equipment, but it still needs some love to stay in good shape; whenever you use chalk, brush the chalk off. Don't use a wet cloth, as that will only make the chalk go deeper into the knurling.
