Single row deep groove ball bearings with filling slots accommodate more balls than standard deep groove ball bearings. They are of a simple, yet versatile, design and are robust in operation, requiring little maintenance. They can accommodate radial and axial loads in both directions. They have a higher radial load carrying capacity than the corresponding bearings without filling slots but have a limited axial load carrying capacity due to the filling slots. Simple, versatile and robust design Accommodate higher radial loads than corresponding bearings without filling slots, with limited axial loads in both directions Require little maintenance

Radial run-out

Deep groove ball bearings are versatile components designed for radial and axial load support in high-speed applications. Their single-row construction with uninterrupted raceways ensures smooth operation under combined loads, while the deep raceway geometry enhances radial load capacity. Precision-ground steel balls and rings minimize friction, reducing energy loss and heat generation. Available in shielded, sealed, or open configurations, these bearings accommodate diverse lubrication needs and contamination protection levels. Common materials include chrome steel for general use and stainless steel for corrosive environments, with optional polymer cages for noise reduction in electric motors.

These bearings excel in efficiency and durability, offering low torque for energy-sensitive applications like HVAC systems or electric vehicle drivetrains. Their ability to handle misalignment (up to 0.5 degree ) simplifies installation in shaft assemblies. With dynamic load ratings reaching 25 kN and speed factors (dn) exceeding 200,000 mm/min, they outperform many bearing types in rotational precision. Pre-greased variants eliminate relubrication needs in sealed units, and advanced sealing technologies (such as triple-lip contact seals) extend service intervals in dusty industrial environments like packaging machinery or conveyor systems.

Cross-Industry Implementation Examples
Widely utilized in automotive alternators, pump shafts, and household appliances (e.g., washing machine drums), deep groove ball bearings also power precision equipment like CNC spindle units and dental handpieces. Their compact design suits robotics joint actuators and drone propulsion systems where weight optimization is critical. In renewable energy applications, specially coated versions withstand moisture in wind turbine yaw systems. Food-grade variants with FDA-compliant lubricants operate reliably in bottling lines, while high-temperature models (up to 150 degree ) serve in oven conveyor rollers, demonstrating adaptability across sectors from aerospace to medical devices.
