Product Introduction

Single Row Cylindrical Roller Bearing NUP203 NU2203ECP NJ2203ECP are different types of ball bearings commonly used in industries such as machinery, automobiles, and wind power generation. Their naming conventions indicate their structural types and some key parameters. Let's analyze and conceptualize the meanings, characteristics, and application scenarios of these models one by one.

1. NUP203

NUP: This is a type of "axial thrust ball bearing" structure, typically designed with inner and outer rings.

203: It is a standard number indicating the size of the bearing. In general, the "203" series of bearings means an inner diameter of 17mm, an outer diameter of 40mm, and a width of 12mm.

characteristic:

NUP203 belongs to a type of bearing with a detachable outer ring, suitable for withstanding small axial forces and radial loads.

Commonly used in small and medium-sized mechanical equipment, such as electric motors, pumps, automotive drive systems, etc.

2. NU2203ECP

NU: This type of bearing belongs to the "no inner ring" design, where the outer ring can rotate freely but without an inner ring.

2203: The size number of the bearing indicates an inner diameter of 17mm, an outer diameter of 40mm, and a width of 12mm.

ECP: The bearing is equipped with a seal (usually rubber seal), which is commonly used to prevent lubricant leakage and prevent external dust from entering.

characteristic:

This type of bearing design is typically used in environments that require high speeds and long-term use, capable of resisting external pollutants and reducing friction.

The sealing structure can effectively prevent pollutants from entering the interior of the bearing, reduce bearing wear, and improve its service life.

3. NJ2203ECP

NJ: Similar to NU bearings, but NJ designs typically include an additional side support that can withstand larger axial loads.

2203: indicates the size of the bearing, which is the same as NU2203ECP, with an inner diameter of 17mm, an outer diameter of 40mm, and a width of 12mm.

ECP: Similar to NU2203ECP, it indicates a sealed structure.

characteristic:

The design of NJ bearings is more suitable for withstanding larger axial loads than NU bearings.

Suitable for situations where both axial and radial loads need to be borne simultaneously.

Application

Single Row Cylindrical Roller Bearing NUP203 NU2203ECP NJ2203ECP fit different areas:

NUP203: Suitable for applications with small axial loads, typically used for simpler mechanical equipment.

NU2203ECP: No inner ring design, suitable for high-speed and harsh environmental applications, and has a sealing function to prevent contamination.

NJ2203ECP: Similar to NU2203ECP, but with stronger axial load capacity, suitable for equipment that needs to withstand both axial and radial loads simultaneously.
