  • Product Overview

    The NJ211E is a single row, cylindrical roller bearing designed for high radial load capacity and moderate axial load handling. It is a locating bearing, meaning it can guide the shaft axially in one direction, making it suitable for applications requiring precise axial positioning. The bearing is typically made from high-grade chrome steel (AISI 52100) and is available in various configurations (e.g., with pressed steel or brass cages).


    Design Features

    NJ Design: The nj211e bearing has two integral flanges on the outer ring and one on the inner ring. This configuration allows it to accommodate axial displacement in one direction, making it ideal for locating a shaft axially.

    Increased Capacity (E-Type): The "E" designation indicates an optimized internal design with a larger roller diameter and length, resulting in a 20-30% higher load-carrying capacity than standard NJ211 bearings.

    Separable Design: The inner ring and roller assembly can be separated from the outer ring, which simplifies mounting, dismounting, and maintenance, especially in applications where interference fits are required.

    Cage Options: Typically equipped with a glass-fiber reinforced polyamide (PA66) cage (designated as "CP" or "TVP"), which is lightweight, durable, and suitable for high speeds. Some variants may feature brass or pressed steel cages for specific applications.


    Installation Notes

    Axial Guidance: The NJ design can only accommodate axial loads in one direction. For bidirectional axial location, a second bearing (such as an NUP type) or a locating ring is required on the opposite side.

    Internal Clearance: Standard variants typically come with normal radial internal clearance (C0/CN). For applications with specific thermal expansion requirements, C3 or C4 clearance variants are available.

    Lubrication: Nj211e bearing suitable for both grease and oil lubrication. The open design allows for easy relubrication in service.


    Common Suffix Variations

    NJ211E (Standard): Often features a pressed steel cage, standard load ratings.

    NJ211EM: Features a machined brass cage (M suffix), suitable for high-speed applications or where cage stability is critical.

    NJ211ECP: SKF designation for bearings with a polyamide cage (CP suffix), offering good speed capability and resistance to wear.


    Applications

    The NJ211E cylindrical roller bearing is widely used in machinery where high radial loads and precise axial location are critical. Common applications include:

    • Electric motors and generators

    • Gearboxes and transmissions

    • Machine tool spindles

    • Pumps and compressors

    • Industrial fans and blowers

    • Rolling mill equipment


    FAQ

    Q1: What does “NJ211E” mean and is it interchangeable with SKF / FAG / NSK NJ211E?

    “NJ” means the bearing has two integral flanges on the outer ring and one on the inner ring, so it carries heavy radial loads and locates the shaft in one direction. The “E” indicates an optimized internal design with larger rollers, giving about 20–30% higher radial load capacity than a standard NJ211. HECTO NJ211E follows the same boundary dimensions—55 mm bore × 100 mm OD × 21 mm width—so it can replace SKF NJ211ECP, FAG NJ211-E-TVP2, NSK NJ211ET and NTN NJ211E in motors, gearboxes and pumps. For bidirectional axial location, pair it with an NUP type or locating ring.


    Q2: What cage, clearance and precision options are available for NJ211E?

    HECTO supplies NJ211E with polyamide (PA66) cage, machined brass cage, or stamped steel cage.

    • PA66 cage: good for high speed, low noise, general electric motors

    • Brass cage (NJ211EM): better for shock loads, higher temperature, heavy industrial drives

    • Steel cage: economical, robust for medium-duty gearboxes
      Radial clearance: C0/CN, C2, C3, C4, C5. Precision: P0, P6, P5. Tell us the application and we will recommend the correct suffix equivalent.


    Q3: What are the load and speed characteristics of NJ211E?

    NJ211E dynamic radial load is around 86 kN and static radial load around 98–99 kN (typical E-type data; exact value confirmed by inspection report). It supports both grease and oil lubrication, with limiting speed depending on cage and lubrication method. Because of convex super-finished rollers and optimized roller set, it offers lower friction, better load distribution and longer life than non-E cylindrical roller bearings in the same size.


    Q4: Why source NJ211E from HECTO instead of a trader?

    HECTO is an IATF16949-certified cylindrical roller bearing manufacturer with 20+ years of export experience. For NJ211E we provide:

    • GCr15 / 100Cr6 bearing steel, super-finished raceways and convex rollers

    • 100% inspection before shipment

    • MOQ from 1 pc, 30–60 days lead time, >99% on-time delivery from Shanghai / Ningbo / Qingdao

    • OEM / ODM private label (HECTO, neutral, or customer brand)

    • Batch-level traceability and inspection / material documents on request
      Buyers get factory-direct pricing with documented quality control, not just a low quote.
