6001 Deep Groove Ball Bearing 12x28x8mm
The 6001 bearing is the standard 12mm-bore deep groove ball bearing in the ISO 600 series: 28mm OD, 8mm width, 5.10 kN dynamic load at 28,000 RPM. Weighing 22 grams with a radial cross-section of 8mm, it steps up from the 6000 bearing (10mm bore) for applications requiring a larger shaft. 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 28,000 RPM with non-contact labyrinth protection. 2RS rated to 20,000 RPM with positive contact sealing against moisture and fine dust.
Speed and Load: 34,000 RPM (open) with 5.10 kN dynamic and 2.37 kN static load. ZZ configuration rated to 28,000 RPM with grease. 2RS configuration rated to 20,000 RPM due to seal friction.
Radial Fit: 12mm bore, 28mm OD, 8mm width. 8mm radial cross-section; 22 grams. 8 balls of 4.762mm diameter, pressed steel two-piece riveted cage. The 12mm bore is the standard step up from the 10mm-bore 6000 bearing.
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 6001 bearing ships in three sealing configurations. Open (no suffix) suits oil-bath and oil-mist lubricated housings where speed is the priority; it reaches 34,000 RPM with oil and 28,000 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, matching the open variant grease speed at 28,000 RPM. 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 20,000 RPM.
At 8mm width and 28mm OD, the 6001 bearing has a radial cross-section of 8mm. The 2RS bearing seals do not compromise the load path; the full 5.10 kN dynamic rating applies regardless of seal type. Factory fill is lithium soap grease for standard applications. Polyurea, fluorinated high-temperature, and food-grade NSF H1 greases are available for volume orders.
Performance
The 6001 bearing carries 5.10 kN dynamic and 2.37 kN static load at 28,000 RPM in ZZ bearing configuration. Part of the deep groove ball bearing family, the 60xx extra-light series spans bore sizes from 3mm to 30mm. GCr15 chrome steel rings hardened to 60-64 HRC through controlled-atmosphere austenitizing at 840C, oil quench, and temper at 160C. The 8mm radial cross-section provides sufficient ring stiffness that the full rated load applies without de-rating for housing compliance.
Compared to the 6201 bearing (12x32x10mm, 6.82 kN dynamic), the 6001 bearing gives up 1.72 kN of capacity but saves 4mm in OD and 2mm in width, weighing 22g versus 37g. For a 12mm shaft where space and weight are constrained, the 6001 bearing delivers comparable performance in a lighter package. Compared to the 6000 bearing (10x26x8mm, 4.55 kN), the 6001 bearing adds 0.55 kN capacity and 2mm bore diameter. L10 life at rated load and 3,000 RPM is approximately 5.5 hours; at half load (2.55 kN), L10 exceeds 8,000 hours with clean lubrication and proper mounting.
OEM and Customization
Through custom bearing manufacturing, Yuanhe produces the 6001 bearing to your specifications. Common OEM requests include C2 or C3 internal clearance grades, polyurea low-noise grease for electric motor applications, fluorinated grease for continuous operation above 100C, NSF H1 food-grade grease, black oxide or zinc-nickel surface treatment, FKM seals as an alternative to standard NBR, 440C stainless steel rings and balls for washdown environments, and private labeling with laser marking. Standard lead time is 7 to 15 days. Batch-level dimensional reports and material certifications ship with every order.

Conveyor rollers, pumps, and textile machinery
Frequently Asked Questions
What is the difference between 6001 bearing and 6201 bearing? +
Both have a 12mm bore. The 6001 bearing has a 28mm OD, 8mm width, and 5.10 kN dynamic load. The 6201 bearing steps up to 32mm OD, 10mm width, and 6.82 kN dynamic. The 6001 bearing saves 4mm in OD and 2mm in width, weighing 22g versus 37g. Choose the 6001 bearing when enclosure diameter and weight are the limiting factors; choose the 6201 bearing when maximum load capacity takes priority.
How does the 6001 bearing compare to the 6000 bearing? +
The 6001 bearing has a 12mm bore versus 10mm for the 6000 bearing. OD increases from 26mm to 28mm. Dynamic load rises from 4.55 kN to 5.10 kN, a 12 percent gain. Static load increases from 1.96 kN to 2.37 kN. Weight goes from 19g to 22g. If your shaft is 10mm, use the 6000 bearing. If you need a 12mm shaft with more capacity, the 6001 bearing is the direct step up in the extra-light series.
Can the 6001 bearing handle radial and axial loads simultaneously? +
Yes. As a deep groove ball bearing, the 6001 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 to determine actual life reduction. The deep groove geometry supports moderate axial thrust in both directions without modification.
What grease options are available for the 6001 2RS bearing? +
Standard fill is polyurea-thickened mineral grease, approximately 100 cSt at 40C, rated -20C to 120C. Custom options include filtered low-noise polyurea for motor applications, fluorinated high-temperature grease for continuous operation to 150C, and food-grade NSF H1 aluminum-complex grease.
