NTN NJ 2207 ET2X 35 x 72 x 23 mm Cylindrical Roller Bearing

NTN NJ 2207 ET2X 35 x 72 x 23 mm Cylindrical Roller Bearing

The NTN NJ 2207 ET2X is a single‑row cylindrical roller bearing built to ISO dimensions 35 mm inner diameter x 72 mm outer diameter x 23 mm width, offering exceptional performance under heavy radial loads.

As part of NTN’s ET2X series, this bearing features:

• A polyamide (nylon) cage (T2X) for reduced friction and higher speed limits

• Enhanced E-type radial load capacity structure for durability

• Separable design: plain inner ring, outer ring with two ribs (NJ type) enables easier installation and alignment

• Weight ~0.40 kg, standard radial clearance class CN

Key Benefits:

• High radial load capacity with excellent stability under pressure

• Reduced mass & friction thanks to lightweight polyamide cage

• Modular construction - inner and outer rings installable separately

• Reliable quality from NTN - designed for long life and demanding industrial use

Ideal applications include heavy-duty industrial machinery, speed-critical drives, conveyors, gearboxes, and any system where high radial loads and robust reliability are required.

FAQ - Most Asked Questions

Q1: What are the exact dimensions of NJ 2207 ET2X?
A: Bore Ø 35 mm, outer Ø 72 mm, width 23 mm; weight approximately 0.40 kg

Q2: What does ET2X mean in NTN bearings?
A: "E" denotes increased radial capacity; T2X indicates a polyamide cage designed for higher speed and longevity
