GQZ 6021-2Z Single Row Deep Groove Ball Bearing 105×160×26mm Double Sided Metal Dust Shields For Industrial Equipment

6021-2Z is single-row deep groove ball bearing equipped with double-sided stamped metal dust shields. It can withstand radial load and moderate bidirectional axial load at the same time, featuring low friction coefficient, stable high-speed operation and reliable dust blocking performance. Metal shields only block dry dust and particles without waterproof performance, ideal for dry, clean medium-heavy load industrial machinery.

1. Double thin metal shields isolate dry dust, metal scraps and dry impurities, greatly extending bearing service life under dry working conditions
2. Continuous deep raceway structure supports composite radial-axial load, suitable for both horizontal and vertical shaft mounting
3. Light stamped steel cage reduces friction heat and guarantees smooth long-time high-speed rotation
4. Standard ISO metric dimension, fully interchangeable with all mainstream brand 6021-2Z bearings
5. Pre-filled universal lithium grease during production, lowering frequent relubrication maintenance work
6. Customizable options: C3 clearance, high-temperature grease, OEM laser marking, P6 / P5 precision grade

Effectively reduce abnormal vibration, running noise and equipment maintenance frequency.

• Large industrial driving motors, ventilation fans and blowers
• Heavy-duty water pumps, medium-sized air compressors and power machinery
• Textile, printing and packaging equipment rotary rollers
• Conveyor rollers, large fitness equipment and industrial household appliances
