Bearing Solutions For The Ceramic Industry
The machinery and equipment used in the ceramic tile industry have evolved with time, requiring high-performance bearings that can cope with the challenges present inside the plant. Therefore, NBC Bearings offers sustainable and comprehensive bearing solutions that can sustain harsh operating conditions.
Features & Benefits
Here are some reasons why bearings offered by us are the best solutions fitting for long term use in the ceramics industry:
- An extensive range of products suitable for demanding environments.
- Longevity of service life as it can withstand humidity, dust and high-speed application.
- Special products are made of advanced materials, special seals, and lubricants.
- Condition monitoring service to prevent any unplanned stoppage
- Low maintenance and maximized uptime makes it economical and reliable.
Bearing Applications
The ceramic industry also has a lot of underlying operating challenges which pose a roadblock in smooth processing of the manufacturing process. The most significant challenges are:
- Low speed due to various reasons
- Contamination that can lead to major downtime
- Vibration that is directly related to increased friction
- Heavy loads which need careful monitoring and maintenance.
- Optimized internal geometry for lowered friction and improved precision
- Seal design to prevent environmental contaminants
- Special heat treatment to prevent overheating and eliminating downtime to great extent
- High-load carrying capacity for proper flow
- High-operational reliability which means low on maintenance
Ceramic Bearing Styles and Sizes
Steel Cage Bearings:
- Surface hardened and lightweight cage design
- Suitable for high-speed applications
- Gives adequate performance for majority of applications
Brass Cage Bearings:
Brass cage bearings can deliver extra durability in extreme operating conditions
- Better performance in shock load applications
- Suitable for high centrifugal loading
- Better performance in reversing application
- Two-piece cage design: This allows both rows to run independently, avoiding the risk of roller slippage, smearing and cage damage.
- Enhanced roller finishing to reduce friction: Enhanced race/roller surface finish results in improved lubrication film, which avoids metal-to-metal contact and lowers bearing operating temperature.
- Improved and robust cage design: Helps in better roller cage interaction and can accommodate more rollers and longer cage life by providing surface treatment.
- Central Guide Ring/Flange: The central guide ring/flange provides optimal guidance to the rollers and limits rollers skew thus, avoids unnecessary force on the cage.
- Maximum and Larger Rollers: This enhances load carrying capacity.
- Size range: 30-2000 mm OD
- Variants: Straight bore, Tapered bore (1:12, 1:30)
- Cage: Brass, Steel
- Clearances: C2, CN, C3, C4, C5
HCR Wear Resistant Bearings
Wear resistance coating on rolling elements helps avoid metal to metal contact in low film thickness and protects against adhesive and abrasive wear.
Features & Benefits
Features & Benefits
- Optimized coating with metal-containing amorphous carbon with a multilamellar structure
- No columnar structure provides high adhesion strength
- High dimensional accuracies
- Low coefficient of friction even in dry condition: Resistant to adhesive wear and micro pitting
- Enhanced fatigue life in insufficient lubrication condition
- Debris tolerance: removes dents created in the contaminated application
Oil Impregnated Bearings
Features & Benefits
Oil impregnated bearings composed of 70-80% of lubricating synthetic oil. Oil is moulded and solidified with polymer to form a casing which acts as a lubricant reservoir throughout the bearing’s life.
