Deep Groove Ball Bearings
Deep groove ball bearings are the most common rolling bearing design, featuring deep raceway grooves that enable them to carry radial loads and moderate axial loads in both directions. SKF deep groove ball bearings are available in a vast range of sizes, with open, shielded (Z), and sealed (RS, RSH, RZ) variants, and can be pre-greased for life. Their simple, robust design and low friction make them suitable for high-speed applications like electric motors, fans, and pumps. SKF Explorer quality bearings offer improved steel cleanliness and optimized raceway geometry, resulting in significantly longer service life and quieter operation. Cages are available in polyamide, steel, or brass depending on temperature and speed requirements. Whether for a small appliance or a large industrial gearbox, deep groove ball bearings provide a reliable, cost-effective solution for a wide variety of rotating machinery.

Sealed Deep Groove Ball Bearings vs. Shielded: Which to Choose?
Shielded bearings (suffix 2Z) are suitable for clean environments where low friction is critical, while sealed bearings (2RS, 2RSH) are preferred in dusty or wet conditions. Contact seals provide better contamination protection but increase friction slightly; non-contact RZ seals offer a compromise. SKF guides help you select the right closure for your operating environment.
Applications of Deep Groove Ball Bearings in Industrial Machinery
From blower motors in HVAC systems to gearbox input shafts and conveyor idlers, deep groove ball bearings are found everywhere. Their adaptability, combined with standard dimensions and worldwide availability, makes them the default choice for rotating shaft support in machines designed for standard operating conditions.
