Deep Groove Ball Bearing

1.Product Introduction: Capable of bearing both radial loads and slight axial loads simultaneously. It features a simple structure, high rotational speed, and convenient maintenance, with extremely strong industrial versatility.
2.Structure Type: Inner ring + outer ring (with circular arc raceway) + single-row steel balls + cage. Some are equipped with seals.
3.Size Range: Inner diameter: 10 - 600mm, outer diameter: 26 - 800mm, width: 8 - 150mm.
4.Material: Inner ring / outer ring: GCr15/GCR15SIMN/20Cr2Ni4A, rolling elements (steel balls): GCr15/GCR15SIMN, cage: stamped steel / brass.
5.Accuracy: Conventional P0/P6 grades, precision models are of P5 grade, and high-speed models are of P4 grade.
6.Sealing: Open type / 2RS (double-sided rubber seal) / 2Z (double-sided iron seal).
Application Fields: Motor spindles, water pumps, fans, automobile transmissions, light industrial equipment.
7.Key Inspection Items: Radial clearance, integrity of seals (for sealed models), accuracy of steel ball arrangement, running noise.

Automotive & Appliances: Low-noise DGBB-XT Series bearings enhance efficiency in transmissions and HVAC systems.

Quality Assurance & Global Logistics

Every bearing undergoes 100% testing for noise, vibration, and load capacity to guarantee a 99.9% qualification rate. We maintain 1,000+ standard models in stock for 48-hour global dispatch.

FAQs

Q: Can your deep groove ball bearings handle frequent start-stop cycles in automotive applications?
A: Yes! Our DGBB-XT Series uses hybrid ceramic balls and reinforced cages for 200,000+ operational cycles.

Q: Do you offer food-grade lubrication options for this ball bearing line?
A: Absolutely. We use NSF H1-certified greases for food processing machinery and hygienic bearing units.

Q: What makes your medical-grade deep groove ball bearings unique?
A: Stainless steel construction and ultra-clean packaging eliminate particle contamination in critical bearings.
