Cylindrical Roller Bearing NJ1014EM 70*110*20mm for Industrial Machinery | GQZ Bearing

The NJ1014EM Single Row Cylindrical Roller Bearing is designed for high radial load capacity and medium-to-high speed industrial applications, offering rigid shaft support with axial location in one direction. It is widely used in heavy-duty gearboxes, industrial pumps, and electric motors where high radial stability and durability under heavy vibration are required.

Technical Specifications

• Model: NJ1014EM (Equivalent: NJ1014-M / NJ1014-M1)

• Inner Diameter (ID): 70 mm

• Outer Diameter (OD): 110 mm

• Width: 20 mm

• Structure: Single Row Cylindrical Roller Bearing with Brass Cage

• Material: Premium Chrome Steel (GCr15 / 100Cr6)

• Cage Material: Machined Solid Brass (M / EM)

• Limiting Speed: ~8,500 rpm (depending on lubrication method)

Key Advantages

• High Radial Load Capacity: Engineered with a solid brass cage and optimized roller geometry to handle extreme radial stress with minimal friction.

• Single-Direction Axial Location: Built with two integral flanges on the outer ring and one flange on the inner ring to accommodate single-direction axial displacement.

• Machined Brass Cage (EM/M): Provides superior strength, thermal stability, and shock resistance compared to standard steel or polyamide cages.

• Compact Thin-Section Design: Offers a high load rating while maintaining a low-profile 20mm width section for space-constrained assemblies.

• Custom Clearance & Tolerance Support: Available in C2, C0, C3, and C4 clearances as well as OEM custom manufacturing.
