High Temperature Deep Groove Ball Bearing With Double Metal Shields

Product Introduction

High temperature deep groove ball bearings are designed based on standard single-row deep groove ball bearings, with an optimized structure to ensure reliable performance under extreme temperature conditions. Their overall geometry is similar to standard bearings, but internal components and clearances are specifically adapted for high-temperature operation.

These bearings are not designed with filling slots, allowing them to withstand moderate radial loads as well as axial loads in both directions. By incorporating extra-large internal clearance and a special high-temperature cage, they effectively prevent seizure caused by rapid heating or cooling cycles.

Operating Conditions

• Operating Temperature: Suitable for continuous operation at elevated temperatures

• Load Conditions: Moderate radial loads and bidirectional axial loads

• Speed: Medium to high speed depending on bearing series and lubrication

• Environment: Suitable for high-temperature, dry, or polluted environments

• Thermal Cycling: Designed to withstand rapid temperature changes without sticking

Key Advantages

• Extra-large internal clearance
  Clearance up to four times C5 clearance, effectively preventing bearing seizure during rapid cooling or thermal expansion.

• Special high-temperature cage design
  Ensures structural stability and reliable operation at elevated temperatures.

• Excellent load-carrying capability
  Can handle both radial loads and axial loads in two directions.

• Multiple high-temperature series available
  Covers a wide range of temperature, speed, and environmental requirements.

• Optional double metal shields (2Z)
  Provides additional protection against dust and solid contaminants.

Structural Types

• VA201 – Most commonly used high-temperature deep groove ball bearing

• 2Z/VA201 – High-temperature bearing with double metal dust shields

• 2Z/VA208 – Suitable for higher operating temperatures

• 2Z/VA228 – Designed for higher temperatures and higher speeds (advanced high-temperature solution)

• 2Z/VA216 – Designed for severely polluted or contaminated environments

Applications

High temperature deep groove ball bearings are widely used in applications such as:

• Industrial ovens and furnaces

• Drying equipment

• Conveyor systems in high-temperature environments

• Steel and metallurgy equipment

• Cement and glass manufacturing machinery

• Heat treatment equipment

• High-temperature fans and motors

OEM / Customization

This bearing supports OEM services and customization, allowing customers to specify brand labeling, lubrication options, precision tolerances, or packaging according to their requirements. It can be tailored to meet unique operational needs, ensuring optimal performance and full compatibility with customer-specific equipment.
