Plain bearings
In harsh operating conditions, equipment components are subject to increased loads, overheating, and accelerated wear. In such cases, NTE plain bearings provide an optimal solution, ensuring low friction and stable performance under intensive operating modes.
Size range
A wide range of sizes makes it possible to buy plain bearings for both light-duty drives and heavy equipment with high requirements for accuracy and service life:
- Bore diameter: from 10 mm to 1000 mm – for shafts of various classes.
- Outside diameter: from 30 mm to 560 mm – universal housing fit.
- Bearing width: from 10 mm to 1320 mm – flexibility for specific tasks.
Design and operating principle
- Bearing base: cylindrical or spherical bushing that supports the shaft and provides controlled sliding.
- Working surface materials: bronze, metal-polymer compounds, or PTFE-based composites, which increase wear resistance and allow operation under high loads and temperature fluctuations.
- Anti-friction coating: special treatment or self-lubricating composite that minimizes friction and heating.
- Bearing geometry: tight and precise fit on the shaft and in the housing for uniform load distribution.
Technical specifications
- Maximum rotational speed: up to 17,000 rpm – at nominal loads.
- Operating temperature range: from −30 °C to +120 °C (depending on the material and design of the bearing).
- Basic dynamic load rating: up to 40.5 kN under nominal operating conditions.
Industrial advantages
- Smooth and quiet operation of equipment – due to minimal friction and optimal design.
- Load stability – optimized bushing geometry and precise fit reduce backlash and vibration.
- Self-lubricating properties – some models operate without additional lubrication, which simplifies maintenance of hard-to-reach components.
- Easy installation and replacement – bushings are easily mounted on shafts and in housings.
- Resistance to misalignment – spherical plain bearings compensate for installation inaccuracies and ensure smooth rotation.
Fields of application
Wholesale plain bearings are widely used across multiple industrial sectors:
- Mechanical engineering.
- Metallurgy.
- Agriculture.
- Energy.
- Mining.
Plain bearings types
The catalogs of plain bearings from NTE include the following types:
- Spherical plain bearings – for assemblies with rotary or overloaded movements. They compensate for shaft misalignment and installation inaccuracies, and are resistant to sudden impacts and high loads.
- Dry sliding bushings – metal-polymer models, sliding washers, products with a PTFE layer, and special composite designs do not require lubrication throughout their entire service life or for most of it.
