bearing , Iran

A bearing is a mechanical component that supports radial and axial loads while enabling rotational or linear motion of shafts with minimal friction. Bearing materials are typically chrome steel or alloy steel with surface hardness of 58–62 HRC and tensile strength of 900–1200 MPa. Load capacity ranges from 500 to 5000 kg depending on type. Dimensional tolerance follows ISO P0–P6, with lubricant film thickness controlled between 0.01–0.05 mm. Operating rotational speed ranges from 500 to 12,000 RPM depending on the bearing type ball, roller, needle, or tapered.

Structurally, the bearing consists of an inner ring, outer ring, cage, and rolling elements. Rolling elements can be balls, rollers, or needles, lubricated with industrial oils or greases of 32–220 cSt viscosity. Cage and groove design ensures even load distribution, minimizing vibration and heat. Hardened and polished contact surfaces provide service life up to 50,000 working hours. This design ensures stable operation and reduces wear in engines, gearboxes, pumps, and industrial machinery.You can order and buy bearing from Iran by contacting us through whatsaap and email.
