Features:
1. Low density. This reduces centrifugal force at high speeds, allowing the bearing to operate more efficiently and at higher RPMs.
2. Moderate elastic modulus. Prevents stress concentration and improves load distribution, increasing the bearing's durability.
3. Low thermal expansion coefficient. Ensures stable performance across a wide temperature range, ideal for high-temperature environments.
4. High compressive strength. Makes it suitable for heavy-duty applications where high stress is involved.
5. High hardness and toughness. Offers excellent surface finish and resistance to external damage, such as particles or shocks.
6. Good fatigue resistance. Provides long service life with minimal wear and tear, even under continuous operation.
7. Suitable for special conditions. It can withstand high temperatures, corrosion, and maintain stability in harsh environments.
Applications:
Silicon nitride ceramic balls are widely used in bearings due to their low density, moderate elastic modulus, small thermal expansion coefficient, high hardness, and good heat and corrosion resistance. These properties significantly improve the contact fatigue life of bearings and expand their use in various high-precision, high-speed applications such as machine tools, automotive systems, racing, subway systems, motors, aerospace engines, petrochemical equipment, and metallurgical machinery.

Expansion joints reduce vibration, dampen sound, and accommodate movement in piping systems.
There are two primary types of expansion joints-metal and non-metallic or elastomeric. Metal expansion joints are constructed in a bellows configuration from thin-gauge material designed to absorb mechanical and thermal movement. Elastomeric expansion joints, by contrast, are fabricated from natural or synthetic rubber and fabric. Consisting of an inner elastomeric tube fused to a metal-reinforced fabric body and an elastomeric cover, these types of expansion joints accommodate greater pipe movement and provide more abrasion resistance than metal joints.
