Design
Deep groove ball bearings are widely used in many industries for decades. A deep groove is formed on each inner and outer ring of the bearings enabling them to sustain radial and axial loads or even combinations of both. As the leading deep groove ball bearing factory, TPI Bearings owns abundant experience in designing and producing this type of bearing.

Inner and outer rings

• Standard bearing steel with a content of carbon and chromium was selected and hardened to withstand the intense pressure between the rolling elements and bearing rings.
• Carbonitriding on both inner and outer rings is a basic hardening process for TPI deep groove ball bearing factory. Through this special heat treatment, hardness on the raceway surface is increased; which reduces wear accordingly.
• Ultra-clean steel is available in some product series from TPI ball bearings suppliers now, higher wear-resistance is obtained accordingly. Since contact fatigue is often caused by hard non-metallic inclusions, deep groove ball bearings nowadays require exceptional levels of cleanliness.

Rolling element

• Steel balls with up to G3 grade ensure TPI deep groove ball bearing factory has the best stability and this also reflects in bearing performance under high speed rotation.
• Ceramic balls is an additional option, when it comes to severe operating conditions. Extreme high speed rotation, heavy-duty applications and high heat generation while operating are some stiuations that ceramic balls can definitely help.
