6003 Deep Groove Ball Bearing 17x35x10mm
The 6003 bearing is the 17mm-bore deep groove ball bearing in the ISO 600 series: 35mm OD, 10mm width, 6.00 kN dynamic load at 22,000 RPM. Weighing 39 grams with a radial cross-section of 9mm, it carries the highest absolute load in the 60xx extra-light family. The 10mm width and 9mm section height give it enough ring mass to sustain 6.00 kN without de-rating. Open, ZZ, and 2RS configurations cover clean high-speed, dust-protected, and washdown environments.
Key Specifications
Sealing: Open, ZZ (metal shields), or 2RS (rubber seals). ZZ reaches 22,000 RPM with non-contact labyrinth protection. 2RS rated to 16,000 RPM with positive contact sealing against moisture and fine dust.
Speed and Load: 26,000 RPM (open) with 6.00 kN dynamic and 3.25 kN static load. ZZ configuration rated to 22,000 RPM with grease. 2RS configuration rated to 16,000 RPM due to seal friction.
Radial Fit: 17mm bore, 35mm OD, 10mm width. 9mm radial cross-section; 39 grams. 9 balls of 5.556mm diameter, pressed steel two-piece riveted cage. The 17mm bore is the largest standard size in the extra-light 60xx series.
Temperature Range: -20C to 120C with standard polyurea grease. 150C peak available with high-temperature fluorinated lubricant.
Precision: Standard ABEC-1. ABEC-3 available for tighter bore tolerance (+0/-0.008mm) and reduced radial runout.

Shielding and Lubrication
The 6003 bearing ships in three sealing configurations. Open (no suffix) suits oil-bath and oil-mist lubricated housings where speed is the priority; it reaches 26,000 RPM with oil and 22,000 RPM with grease. ZZ bearing uses double SPCC steel shields pressed into the outer ring. These non-contact labyrinths block coarse debris with zero seal drag. 2RS bearing uses NBR rubber contact seals riding on the inner ring shoulder for positive protection against moisture, fine dust, and light liquid splash at 16,000 RPM.
At 10mm width and 35mm OD, the 6003 bearing has a radial cross-section of 9mm. The seals do not compromise the load path. Factory fill is lithium soap grease. Polyurea, fluorinated high-temperature, and food-grade NSF H1 greases are available for volume orders.
Performance
The 6003 bearing carries 6.00 kN dynamic and 3.25 kN static load at 22,000 RPM in ZZ bearing configuration. Part of the deep groove ball bearing family, it is the largest bore in the 60xx extra-light series. GCr15 chrome steel rings hardened to 60-64 HRC. Nine balls of 5.556mm diameter distribute contact stress across a larger rolling element than the 4.762mm balls in smaller 6000-6002 bearings.
Compared to the 6203 bearing (17x40x12mm, 9.55 kN dynamic), the 6003 bearing gives up 3.55 kN but saves 5mm in OD and 2mm in width, weighing 39g versus 65g. Compared to the 6002 bearing (15x32x9mm, 5.58 kN), the 6003 bearing adds 0.42 kN capacity and 2mm bore diameter. L10 life at rated load is approximately 5.5 hours; at half load, L10 exceeds 8,000 hours with clean lubrication and proper mounting.
OEM and Customization
Through custom bearing manufacturing, Yuanhe produces the 6003 bearing to your specifications. Common OEM requests include C2 or C3 clearance grades, polyurea low-noise grease for electric motors, fluorinated grease for operation above 100C, NSF H1 food-grade grease, black oxide or zinc-nickel surface treatment, FKM seals, 440C stainless steel rings and balls, and private labeling with laser marking. Standard lead time is 7 to 15 days with batch-level reports.
Applications
Small electric motors, HVAC fans, and condenser units
Power tools, circular saws, and angle grinders
Bicycle hubs, bottom brackets, and pedal assemblies
Conveyor rollers, pumps, and textile machinery
Frequently Asked Questions
What is the difference between 6003 bearing and 6203 bearing? +
Both have a 17mm bore. The 6003 bearing has a 35mm OD, 10mm width, and 6.00 kN dynamic load. The 6203 bearing steps up to 40mm OD, 12mm width, and 9.55 kN dynamic. The 6003 bearing saves 5mm in OD and 2mm in width, weighing 39g versus 65g. Choose 6003 bearing when space and weight are constrained; choose 6203 bearing when maximum load capacity takes priority.
How does the 6003 bearing compare to the 6002 bearing? +
The 6003 bearing has a 17mm bore versus 15mm for the 6002 bearing. OD increases from 32mm to 35mm. Width goes from 9mm to 10mm. Dynamic load rises from 5.58 kN to 6.00 kN. Ball size increases from 4.762mm to 5.556mm. If your shaft is 15mm, use 6002 bearing. If your shaft is 17mm, 6003 bearing is the largest bore in the extra-light 60xx series.
Can the 6003 bearing handle radial and axial loads simultaneously? +
Yes. As a deep groove ball bearing, the 6003 bearing handles combined loading with axial capacity at roughly 25 to 30 percent of the radial dynamic rating. For combined loads, calculate the equivalent dynamic load per ISO 281. The deep groove geometry supports axial thrust in both directions.
What grease options are available for the 6003 2RS bearing? +
Standard fill is polyurea-thickened mineral grease, 100 cSt at 40C, rated -20C to 120C. Custom options include filtered low-noise polyurea for motor applications, fluorinated high-temperature grease to 150C, and food-grade NSF H1 grease.
