Single Row Deep Groove Ball Bearing With Full Complements

No cage installed, maximum quantity of balls filled inside raceways

Higher radial dynamic & static load capacity, 30%~60% heavier load than standard caged bearings of identical dimensions

Excellent rigidity and great resistance to shock and vibration loads

Larger internal grease storage space for long-term lubrication & maintenance-free service

Capable of bearing slight bidirectional axial loads besides heavy radial loads

Simplified structure, cost-effective with fewer components

Full complement deep groove ball bearings have obvious performance advantages compared with conventional caged bearings of the same dimensional specification:

Superior Load Capacity: The increased number of rolling balls boosts radial dynamic and static load by 30%–60%, effectively bearing heavy continuous radial loads.

High Rigidity & Impact Resistance: Dense steel ball arrangement optimizes force distribution, delivering excellent stability against vibration, shock and alternating loads.

Extended Lubrication Cycle: Without a cage structure, the internal cavity provides larger grease storage space, supporting long-term maintenance-free operation under harsh working environments.

Simple & Cost-Effective Structure: Fewer components simplify assembly and reduce failure rates, achieving stable performance with lower comprehensive cost.

Dual-direction Auxiliary Axial Load: Retains the deep groove raceway design, capable of bearing small bidirectional axial loads while bearing main radial loads.

Limitations

Low Speed Only: Without cage guidance, steel balls contact and rub against each other. High-speed operation will cause severe heat, abnormal wear and bearing seizure.

Limited Axial Bearing Capacity: The outer ring ball filling slot breaks the complete raceway contour, so the bearing cannot withstand large or pure axial thrust loads.

Higher Operating Friction: Compared with standard caged bearings, it has larger running torque and higher operating temperature rise.

• Kiln cars & transfer carts – support heavy loads at 200–450°C, slow continuous movement.

• Roller hearth furnaces – guide rolls and conveyor rollers under high heat and dust.

• Tunnel kilns & industrial ovens – dampers, door hinges, and auxiliary rotating parts.

• Ceramic/brick kilns – firing zone conveyors and support rollers at 300–500°C.

• High-temperature fans & blowers – furnace circulation fans with limited lubrication access.
