NACHI thrust ball bearing model 53203 , Iran

The NACHI thrust ball bearing model 53203 is a precision single-direction axial bearing designed to support high axial loads at moderate speeds. It features a 17-millimeter inner diameter, 40-millimeter outer diameter, and a total thickness of 15 millimeters. The bearing consists of two hardened steel washers and a set of steel balls with surface hardness between 60 and 64 HRC. The rings are made from SUJ2 chrome alloy steel, providing excellent resistance to fatigue and wear. Manufacturing tolerances comply with ISO 3245 standards and precision class P6. The optimized raceway geometry ensures uniform load distribution and reduced vibration during continuous operation.

Production of the NACHI 53203 bearing involves ultra-precision grinding and multi-stage heat treatment to enhance service life and motion accuracy. The operational temperature range is from minus 20 to plus 120 degrees Celsius, with stable performance up to 150 degrees under proper lubrication. Lubrication is achieved using lithium-based NLGI-2 grease or ISO VG 68 industrial oil. The maximum rotation speed is 4500 rpm with grease and up to 6500 rpm with oil. This bearing model is widely used in pumps, vertical shafts, and power transmission systems.You can order and buy NACHI thrust ball bearing model 53203 from Iran by contacting us through whatsaap and email.
