GO320 HMS Olympic bar was made of chrome-plated hardened steel. HMS bar is known for its strength combined with perfect flexibility. The set includes bar and 2 collars. Secure and comfortable grip is assured by knurling. The maximum load is 320 kilograms. In turn, the 28mm diameter ensures comfort during workout. Chrome-plated steel guarantees the nice look and long life on the products. It is also a great protection against the rust. GO320 HMS Olympic bar has 2 needle roller bearings (1 on each side), they make the load rotation smooth and quiet. Its construction eliminates stress on the ends of the cylinders, and as a result the bearing can be used longer. Despite its small cross section, needle roller bearings have a high stiffness and load capacity. Two collar clips included in the set, provide a stable position of the weight on the bar during exercise. The clips have the rubber pressure pads so they won’t damage plates or bars yet ensure they’ll stay firmly in place.Specification: Material: hardened chrome plated steel Type: olympic Total length (mm): 1830 Hand grip diameter (mm): 28 Length of the grip section (mm): 1140 Loudable sleeve diameter (mm): 50 Length of load section (mm): 300 Bearings: 2x needle Handle: knurled Bar clamps: 2x jaw collars Maximum load (kg): 320 Product weight (kg): 14,8 Remarks: Warranty 24 month Importer: Abisal Ltd. | Poland | 41-807 Zabrze | Pyskowicka Street 17 | e-mail: abisal@abisal.pl Abisal Ltd.. declares that the products sold by the company are safe and meet the requirements contained in the Act on General Product Safety of December 12, 2003.
