Design variables:
Types N and NU: These types allow for axial displacement between the inner and outer rings, adapting to axial expansion caused by temperature changes. This is useful in applications with large thermal variations.
Type NJ: Provides axial load capability in one direction, making it suitable for applications requiring limited axial support.
NUP type: Provides axial load support in both directions and axial positioning in applications requiring light axial guidance.

Structure and components:
Separable: Single-row cylindrical roller bearings are usually separable, which means that the inner and outer rings can be removed independently. This design simplifies installation, inspection and maintenance.
Roller profile: Rollers are precision-machined with slightly raised tops to prevent edge stress, enhance load distribution, reduce wear and extend bearing life.

Application program:
Motors: Ideal for high-speed motors because they are able to reduce friction while supporting significant radial loads.
Gearboxes and transmissions: Often used for gearboxes with high radial loads because they provide stability under heavy and fluctuating loads.
Pumps and compressor shafts: Common in applications that require reliability, low friction and high durability under constant radial loads.

Advantages:
High radial load capacity: These bearings can support higher radial loads compared to ball bearings due to the linear contact of the cylindrical rollers.
Low friction: They have low rolling friction, making them efficient for high-speed applications.
Thermal expansion adjustment: Some designs (N and NU) allow for axial movement that helps accommodate thermal expansion without putting pressure on the bearing.

More Industry knowledge

At Shaoxing Shangyu Flight Seiko Machinery Co., Ltd. (FTM), we leverage over 30 years of technical expertise to engineer Single Row Cylindrical Roller Bearings that define reliability and precision. Designed to thrive in demanding environments, these bearings are engineered to manage substantial radial loads while maintaining exceptional performance at high rotational speeds.

The core of our design lies in the linear contact between the cylindrical rollers and the raceways. Unlike standard ball bearings, this configuration ensures optimal load distribution across a larger surface area, significantly reducing stress points and minimizing friction. This makes our bearings an essential component for high-stakes industries including automotive transmissions, aerospace turbines, and heavy industrial machinery.

Why Choose FTM for Your Bearing Solutions

As a specialized manufacturer, FTM goes beyond off-the-shelf products. We bridge the gap between standard requirements and high-precision import substitution.

Precision Engineering: We offer ultra-high accuracy levels of P2 and P4, ensuring our bearings meet the tightest tolerances required for CNC machinery and high-speed spindles.
Material Versatility: From standard Gcr15 bearing steel for high durability to stainless steel for corrosion resistance and 45 steel for specific structural needs, we match the material to your environment.
Advanced Surface Treatments: Our in-house processing includes heat treatment, electroplating, and blackening to enhance wear resistance and longevity.
Customization and Geometry: Whether you require specific chamfers, threads, grooves, or complex shapes through specialized casting and forging, FTM provides tailor-made mechanical solutions that integrate seamlessly into your assemblies.

Technical Deep Dive: Extended Knowledge

Single row cylindrical roller bearings are classified based on the presence or absence of ribs on the rings (NU, NJ, NUP, or N types). This determines whether the bearing can accommodate axial displacement in both directions, one direction, or act as a locating bearing. At FTM, our technical team works closely with you to determine the ideal configuration for your lubrication system and housing constraints, ensuring maximum thermal stability and service life.

Frequently Asked Questions (FAQ)

1. What is the maximum precision level FTM can provide for these bearings?
FTM specializes in high-precision manufacturing, offering accuracy grades up to P2 and P4. These levels are ideal for applications requiring minimal runout and high rotational accuracy, often serving as high-quality substitutes for expensive imported brands.

2. Can FTM customize bearings for small-scale equipment?
Yes. We offer specialized sizing for smaller applications, with inner diameters ranging from 10mm to 25mm. Despite their compact size, these bearings maintain the high load-bearing characteristics inherent to the cylindrical roller design.
