Product Introduction

N203 NU203ECP NJ203ECP Cylindrical Roller Bearing are a series of common rolling bearings mainly used to support rotating components in mechanical equipment. Here are the specific product details of these models:

1. N203 (N-type bearing)

Type: N203 is a single row cylindrical roller bearing, belonging to N-type bearings.

Design feature: The N203 bearing has two grooves on the inner ring, while the outer ring does not have grooves, making it suitable for withstanding large radial loads. They are usually used in situations where they need to withstand high-speed rotation or high loads.

Application: Commonly used in industries such as automobiles, mechanical equipment, fans, pumps, etc., especially suitable for applications that require bearing large radial loads.

Size:

Inner diameter (d): 17 mm

Outer diameter (D): 40 mm

Height (B): 12 mm

Characteristic: Unable to withstand large axial loads.

2. NU203ECP (NU type bearing, marked with E)

Type: NU203ECP is also a single row cylindrical roller bearing, belonging to the NU series. The "E" mark means that the bearing is designed with reinforced sealing or protective devices to improve its durability.

Design feature: The inner ring of NU203ECP bearing has no grooves, while the outer ring has two grooves. Suitable for withstanding pure radial loads and is more suitable for use in situations where axial loads need to be avoided.

Application: Widely used in automobiles, heavy machinery, wind turbines and other equipment, suitable for withstanding medium to heavy loads.

Size:

Inner diameter (d): 17 mm

Outer diameter (D): 40 mm

Height (B): 12 mm

Features: The design emphasizes high speed and low friction, which can perform well in high-speed applications.

3. NJ203ECP (NJ type bearing, marked with E)

Type: NJ203ECP is a single row cylindrical roller bearing belonging to the NJ series, also marked with an E indicating an enhanced design. NJ type bearings have a structure with grooves on both the inner and outer rings, which can withstand certain axial loads.

Design feature: Due to its grooved design, NJ203ECP is suitable for applications that require bearing radial and axial loads. The groove design of the inner and outer rings helps to fix the rolling elements and reduce the influence of axial movement.

Application: Suitable for electric motors, mechanical transmission systems, fans, and other equipment that require withstanding large axial forces.

Size:

Inner diameter (d): 17 mm

Outer diameter (D): 40 mm

Height (B): 12 mm

Features: Suitable for situations where both radial and axial loads are applied simultaneously, it has strong load capacity and stability
