6201 Deep Groove Ball Bearing 12x32x10mm
The 6201 bearing closes the gap between miniature bearings and small industrial bearings. At 12mm bore and 32mm OD, its 10mm width gives it 6.82 kN dynamic load capacity in a cross-section that still fits compact motor housings, power tool gearcases, and light conveyor rollers. Compared to a 6001 bearing at the same bore, the 6201 bearing gains 4mm OD and 2mm width for 34 percent more load capacity.
Key Specifications
- Sealing: Open, ZZ (non-contact metal shields), or 2RS (nitrile rubber contact seals). Three configurations for oil-lubricated, dust-protected, and moisture-resistant applications.
- Speed and Load: 20,000 RPM (open) with 6.82 kN dynamic and 3.05 kN static load. 2RS rated to 16,000 RPM due to seal drag.
- Dimensions: 12mm bore x 32mm OD x 10mm width. 10mm radial cross-section provides higher load capacity than 6000-series equivalents at the same bore.
- Temperature Range: -20C to 120C continuous with standard polyurea grease. 150C peak available with high-temperature grease on OEM request.
- Precision: ABEC-1 standard. ABEC-3 available with tighter bore tolerance and reduced radial runout for electric motor and spindle applications.

Shielding and Lubrication
The 6201 bearing ships in three sealing configurations. Open bearings suit gearboxes and oil-mist-lubricated spindles where the system handles contamination; speed reaches 20,000 RPM. ZZ metal shields form a non-contact labyrinth at the outer ring, retaining grease without friction loss. 2RS nitrile rubber seals provide a positive lip contact barrier against moisture, cutting debris, and concrete dust, reducing the speed ceiling to 16,000 RPM. All sealed variants are pre-greased for life with polyurea-thickened mineral grease; no field relubrication is required.
At 10mm width, the 6201 bearing has 2mm more axial cross-section than the 6001 bearing. This extra width accommodates a deeper seal groove with more positive lip contact force without reducing ball diameter. For power tools in construction environments where the bearing faces gypsum dust, concrete slurry, and impact vibration, the 2RS seal is the standard specification. For fan motors and HVAC blowers in relatively clean indoor air, ZZ shields preserve the full 20,000 RPM speed rating while providing adequate dust protection.
Performance
The 6201 bearing carries 6.82 kN dynamic load and 3.05 kN static load at 20,000 RPM in open configuration. Within the 6200-series deep groove ball bearing family, it follows the 6200 bearing (10x30x9mm, 5.10 kN) with a 34 percent load increase from 2mm more bore and OD. The 6202 bearing (15x35x11mm, 7.65 kN) adds another 12 percent with 3mm larger bore. For 12mm shaft applications, the 6201 bearing provides the highest load capacity among standard deep groove bearings at this bore size, exceeding the 6001 bearing (12x28x8mm, 5.10 kN) by 34 percent and the 6301 bearing (12x37x12mm, 9.70 kN) for maximum duty.
Compared to the 6001 bearing (12x28x8mm, 5.10 kN dynamic), the 6201 bearing requires 4mm more housing diameter but delivers 34 percent more capacity. The 2mm width increase from 8mm to 10mm provides a larger ball complement and deeper raceway geometry. In a 0.75 kW power tool motor, upgrading from 6001 bearing to 6201 bearing extends calculated bearing life from approximately 2,000 hours to over 6,000 hours at rated load, a factor of 3 improvement.
OEM and Customization
Yuanhe manufactures the 6201 bearing to customer specifications. Common OEM customizations include C3 radial internal clearance for electric motor and power tool applications where thermal expansion tightens the running clearance under continuous load, C2 clearance for precision spindles, and high-temperature polyurea or fluorinated grease for duty above 120C. Stainless steel (440C) rings and balls serve food processing, marine, and chemical washdown environments; dynamic load rating reduces to approximately 5.5 kN. Cage options include glass-fiber-reinforced PA66 (standard), machined brass, and pressed steel. Non-standard bore tolerances, snap-ring grooves, and extended inner rings are available against drawing review. Standard lead time is 7 to 15 days. Send a part number or drawing for a quote.
Applications
Power tool motors and gearcases (angle grinders, circular saws, hammer drills), small electric motors under 1.5 kW, HVAC fan and blower shaft assemblies, light conveyor head and tail pulleys, domestic appliance drum and motor bearings (washing machines, dryers), fitness equipment pedal cranks and flywheel hubs, small centrifugal pump shafts, textile spinning and winding machine rollers, office equipment paper feed and fuser rollers, and automotive alternator and tensioner pulley bearings where the shaft is 12mm and the housing bore is 32mm.
FAQ
Q1: What is the difference between 6201 bearing and 6001 bearing? +
Both have a 12mm bore. The 6201 bearing measures 32mm OD x 10mm width while the 6001 bearing measures 28mm OD x 8mm width. The 6201 bearing carries 6.82 kN dynamic load, 34 percent more than the 6001 bearing at 5.10 kN. The tradeoff is 4mm more OD and 2mm more width. Choose the 6201 bearing when load capacity exceeds 6001 bearing limits. Choose the 6001 bearing when housing diameter below 30mm is required.
Q2: Can the 6201 bearing replace a 6200 bearing? +
Only with re-machining of the shaft and housing. The 6200 bearing uses a 10mm bore and 30mm OD, while the 6201 bearing requires 12mm bore and 32mm OD. The 6201 bearing carries 34 percent more dynamic load (6.82 vs 5.10 kN) and handles 20,000 RPM compared to 24,000 RPM for the 6200 bearing. If the design can accommodate the larger envelope, the 6201 bearing extends fatigue life by approximately 2.5 times for the same radial load.
Q3: What speed can a 6201 bearing handle in a power tool? +
In open configuration with grease lubrication, the 6201 bearing is rated to 20,000 RPM. Most corded power tools operate at 10,000 to 15,000 RPM, well within the bearing speed rating. In 2RS sealed configuration, the rating drops to 16,000 RPM due to seal lip friction. For angle grinders and circular saws running above 15,000 RPM, ZZ shields or open configuration with external sealing are specified to avoid the seal drag penalty. Contact Yuanhe with your tool speed and duty cycle for a bearing selection review.
Q4: What is the radial internal clearance of a standard 6201 bearing? +
Standard clearance is CN (normal), with radial play of 3 to 18 microns measured under a 5 kgf gauge load per ISO 5753. C3 clearance increases this to 8 to 23 microns, the most common specification for electric motors and power tools where thermal expansion of the shaft reduces running clearance. C2 clearance (0 to 10 microns) serves precision applications requiring minimal radial play. Clearance is verified 100 percent at final inspection and documented in the batch report.
