The fitness equipment linear shaft is a core transmission component designed specifically for fitness equipment. It is precision manufactured by Lishui Hengyuan Bearing Manufacturing Co., Ltd. using high-quality carbon steel or alloy steel materials. The surface is treated with hard chrome plating, mirror polishing, and rust prevention, and has high rigidity, wear resistance, and corrosion resistance. Its outer diameter tolerance strictly follows the G6 and H7 standards, with a straightness error of ≤ 0.05mm/500mm. It is suitable for linear bearings of treadmills, rowing machines, fitness bikes and other equipment (such as LM series), ensuring smooth sliding of equipment moving parts, reducing friction noise, and extending equipment service life.

Core advantages
High load and durability: The static load can reach 120kN, the dynamic load is 60kN, the surface hardness is HRC55-58, and the wear resistance is increased by three times. It is suitable for high-frequency and heavy load fitness scenarios (such as comprehensive trainer bench press, gantry guide shaft).
Precision sports performance: The hard chrome coating thickness is 10-50 μ m, with a friction coefficient as low as 0.002, ensuring that the treadmill platform, rowing machine seats, and other components do not shake or slide, and improving the smoothness of user sports.
Full environmental adaptability: Carbon steel version galvanized/nickel plated for rust prevention, stainless steel version (SUS440C) resistant to sweat corrosion, suitable for high humidity environments in home, commercial, and outdoor gyms.
Modular design: supports end processing (threads, flange holes), adapts to the installation needs of different brands of fitness equipment, and reduces equipment maintenance costs.
