Product Description

Product Description

NO 1. Application of cylindrical roller bearings

Large and medium-sized motors, locomotives, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and lifting and transporting machinery

NO 2. Features of cylindrical roller bearings

1. The roller and the raceway are in line contact or repaired offline contact, with large radial bearing capacity, suitable for bearing heavy loads and impact loads.
2. The friction coefficient is small, suitable for high speed, and the limit speed is close to the deep groove ball bearing.
3. The N-type and NU-type can move axially, can adapt to the change of the relative position of the shaft and the housing caused by thermal expansion or installation error, and can be used as a free end support.
4. The processing requirements for the shaft or the seat hole are relatively high, and the relative deflection of the outer ring axis after the bearing is installed must be strictly controlled to avoid contact stress concentration.
5. The inner ring or outer ring can be separated for easy installation and disassembly.
 
A wide range of applications:

• agriculture and forestry equipment
• automotive and industrial gearboxes
• automotive and truck electric components, such as alternators
• electric motors
• fluid machinery
• material handling
• power tools and household appliances
• textile machinery
• two Wheeler.

Application Industry

Applications:

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.
