6202 Deep Groove Ball Bearing 15x35x11mm
The 6202 bearing is the most widely specified 15mm-bore deep groove bearing in small motors, pumps, and power transmission. At 35mm OD and 11mm width, it carries 7.65 kN dynamic load, 12 percent more than the 6201 bearing from only 3mm additional bore. For design teams moving up from a 12mm shaft, the 6202 bearing is the standard 6200-series step that keeps housing OD under 40mm.
Key Specifications
- Sealing: Open, ZZ (non-contact metal shields), or 2RS (nitrile rubber contact seals). Three configurations for oil-bath, dust-protected, and wet operating environments.
- Speed and Load: 18,000 RPM (open) with 7.65 kN dynamic and 3.75 kN static load. 2RS rated to 14,000 RPM due to seal lip drag.
- Dimensions: 15mm bore x 35mm OD x 11mm width. 10mm radial cross-section balances load capacity against housing envelope for compact motor designs.
- Temperature Range: -20C to 120C continuous with standard polyurea grease. 150C peak with high-temperature synthetic grease on OEM request.
- Precision: ABEC-1 standard. ABEC-3 and P6 (ISO class 6) available for reduced noise and vibration in electric motor applications.

Shielding and Lubrication
The 6202 bearing ships in three sealing configurations. Open bearings suit oil-lubricated gearboxes and engine accessory drives where the system provides contamination control; speed reaches 18,000 RPM. ZZ metal shields form a non-contact labyrinth at the outer ring, retaining grease without friction loss, suited for clean indoor environments. 2RS nitrile rubber seals provide positive lip contact against water splash, agricultural dust, and road debris, reducing the speed rating to 14,000 RPM. All sealed variants are pre-greased for life; no field relubrication needed.
The 11mm width provides 1mm more axial cross-section than the 6201 bearing, allowing a slightly deeper seal groove and larger grease reservoir. For alternator bearings in automotive applications where under-hood temperatures reach 120C and belt dust is present, the 2RS seal is the standard choice. For electric motor applications in clean factory environments, ZZ shields maintain the full speed rating while providing adequate protection against airborne workshop dust.
Performance
The 6202 bearing carries 7.65 kN dynamic load and 3.75 kN static load at 18,000 RPM in open configuration. Within the 6200-series deep groove ball bearing family, it follows the 6201 bearing (12x32x10mm, 6.82 kN) with a 12 percent load increase from 3mm more bore. The 6203 bearing (17x40x12mm, 9.58 kN) adds another 25 percent with 2mm larger bore. For 15mm shaft diameters, the 6202 bearing provides 50 percent more dynamic load capacity than the 6002 bearing (15x32x9mm, 5.10 kN) at the same bore, making it the default choice when housing diameter can accommodate 35mm instead of 32mm.
Compared to the 6002 bearing (15x32x9mm, 5.10 kN dynamic), the 6202 bearing requires 3mm more OD and 2mm more width but delivers 50 percent more load capacity. In a 0.5 kW water pump, upgrading from 6002 bearing to 6202 bearing extends calculated bearing life from approximately 8,000 hours to 25,000 hours under the same radial load. The 2mm width increase from 9mm to 11mm accommodates a larger ball diameter, which reduces contact stress at the raceway for the same applied force.
OEM and Customization
Yuanhe manufactures the 6202 bearing to customer specifications. Common OEM customizations include C3 radial internal clearance for electric motor and alternator applications where thermal expansion reduces running clearance under continuous load, C2 clearance for precision spindle assemblies, and high-temperature grease for duty above 120C. Stainless steel (440C) rings and balls are available for water pump, marine, and food processing applications; dynamic load rating reduces to approximately 6.1 kN. Cage options include glass-fiber-reinforced PA66 (standard), machined brass for high-temperature service, and pressed steel. Non-standard bore tolerances, snap-ring grooves, and double-sealed configurations are available against drawing review. Standard lead time is 7 to 15 days. Send a part number or drawing for a quote.
Applications
Small electric motors under 2.2 kW, automotive alternator and water pump bearings, domestic appliance drum and motor bearings, light conveyor head and tail pulleys, agricultural implement disc and roller bearings, HVAC condenser and evaporator fan motors, small centrifugal and peripheral pump shafts, power tool motor and spindle bearings, fitness equipment crank and flywheel assemblies, and office equipment fuser and paper feed rollers where the shaft is 15mm and the housing bore is 35mm.
FAQ
Q1: What is the difference between 6202 bearing and 6002 bearing? +
Both have a 15mm bore. The 6202 bearing measures 35mm OD x 11mm width while the 6002 bearing measures 32mm OD x 9mm width. The 6202 bearing carries 7.65 kN dynamic load, 50 percent more than the 6002 bearing at 5.10 kN. The tradeoff is 3mm more OD and 2mm more width. Choose the 6202 bearing when load or fatigue life requires it. Choose the 6002 bearing when housing diameter is limited to 32mm.
Q2: Can the 6202 bearing replace a 6201 bearing? +
Only with re-machining. The 6201 bearing uses a 12mm bore and 32mm OD, while the 6202 bearing requires 15mm bore and 35mm OD. The 6202 bearing carries 12 percent more dynamic load (7.65 vs 6.82 kN). If the shaft and housing can be resized, the 6202 bearing extends fatigue life by approximately 1.4 times for the same radial load.
Q3: What is the maximum speed for a 6202 2RS bearing in a pump? +
The 6202 2RS bearing is rated to 14,000 RPM. Most centrifugal water pumps operate at 1,500 to 3,600 RPM, well within the rating. Seal friction temperature rise is under 5C at pump speeds. For boiler feed pumps at 7,200 RPM (2-pole motor), consider ZZ shields with external labyrinth sealing to avoid the 2RS speed penalty.
Q4: What is the standard grease fill for a 6202 2RS bearing? +
Standard fill is polyurea-thickened mineral grease, viscosity approximately 100 cSt at 40C, 25 to 35 percent of free internal volume. For high-speed applications above 10,000 RPM, fill is reduced to 20 to 25 percent to limit churning losses. Custom greases (low-noise, food-grade, wide-temperature synthetic) are available for OEM orders with minimum quantity requirements.
