Product Description

Cylindrical roller bearings are designed with a straightforward structure that consists of cylindrical rollers in contact with linear raceways. One of the key features of cylindrical roller bearings is their high load capacity, especially under mainly radial loads. The roller and ring ribs offer low friction, making these bearings suitable for high-speed rotation
N type:
The inner ring has two integral flanges and the outer ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. The bearings are therefore used as non-locating bearings.
NU type:
The outer ring of bearings of the NU design has two integral flanges and the inner ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself.
NJ type:
The outer ring has two integral flanges and the inner ring one integral flange. The bearings are therefore suitable for the axial location of a shaft in one direction.
NUP type:
The outer ring has two integral flanges and the inner ring one integral flange and one non-integral flange in the form of a loose flange ring. The bearings can be used as locating bearings, i.e. they can provide axial location for a shaft in both directions.
RN type:
No outer ring and the inner ring two integral flanges.

Features:
Excellent Sealing
The potential entry of water and foreign matter is a common concern for many bearings. However, with the use of contact seals, this issue is significantly reduced. By minimizing the risk of contamination, the bearings benefit from a longer lifespan and enhanced durability.

Crane sheaves are often subject to significant radial and thrust loads, which can lead to premature wear and tear if the bearings are not up to the task. Fortunately, these bearings are specifically designed to handle these high demands without any loss of performance.

Related Models

Single-row bearings are classified as NU, NJ, NUP, N, or RN, while double-row bearings are classified as NNU or NN, depending on the use of side ribs. All types of bearings enable the outer and inner rings to be separated.

Application Industry

Applications:
Full-complement cylindrical roller bearings come without cages to allow for maximum roller capacity, which significantly increases their load capacity. However, their high-speed performance is slightly lower than that of bearings with cages. These CRBs are mainly used in applications that require handling of heavy loads at low speeds.

Playground Equipment

Slewing bearing can provide excellent performance experience and safety guarantee for amusement equipment, and the durability of slewing bearing is also the main concern of technical engineers. For more than 20 years, slewing bearing solutions have been used in many key applications of large amusement equipment. reflect.

We designed the cross-sectional area to remain the same as the raceway center distance increased, and the slewing ring achieves better dynamic capabilities with less mass.

Key advantages include:
* Lighter weight
* Save spaighter weightce
* Long life and lower maintenance costs
* Better stiffness
* Better lubrication in extreme conditions

Medical Device
With the comprehensive development of scientific and technological strength, the social economyu has been improved faster, and the medical equipment has also been comprehensively improved.

Mining & construction machinery

Mining machinery and heavy construction machinery industry uses a range of different types of highly specialized mobile machinery. . The places where mining machinery and construction machinery are active are mostly mining sites such as mountains and deserts that are far away from ordinary human life. These heavy machinery work in the harshest environments and require continuous low-friction work without reducing load capacity and minimum. assembly and adjustment time. Solving the bearing heating problem caused by the large exciting force, high vibration frequency and continuous operation of vibratory rollers for users has become the focus of the work. Mineral crushing machinery, cutting machinery, screening machinery, loading machinery, conveying machinery and other equipment in the use environment of bearings, users desire products with robustness, durability and high reliability to resist these harsh working conditions.

Transportation vehicle

Metric and inch needle roller bearings have various structural types, mainly including open drawn cup needle roller bearings, closed drawn cup needle roller bearings, needle roller bearings with inner ring and needle roller bearings without inner ring/without inner ring Cage needle roller bearings, caged and cageless needle roller bearings. Widely used in automobiles, motorcycles, mopeds, power tools, textiles, agricultural machinery, printing machinery, construction machinery, automatic instruments and other fields.

Automatic machinery

Industrial robot bearings mainly include two categories: one is thin-walled bearings, and the other is crossed cylindrical roller bearings. In addition, there are harmonic reducer bearings, linear roller bearings, spherical plain bearings, etc. Bearings with good performance have large bearing capacity, good rigidity, high rotation precision and easy installation.
