6006 Deep Groove Ball Bearing 30x55x13mm
6006 Deep Groove Ball Bearing 30x55x13mm
At 30mm bore and 55mm OD, the 6006 bearing is the first in the 6000-series to cross the 50mm OD threshold, entering the medium-size industrial bearing class. It carries 13.2 kN dynamic load at 12,000 RPM, serving as the default choice for shaft diameters between 25mm and 35mm where a 6206 bearing would overshoot the housing envelope by 7mm.
Key Specifications
- Sealing: Open, ZZ (non-contact metal shields), or 2RS (nitrile rubber contact seals). Three configurations matched to oil-bath, dust-protected, and wet environments.
- Speed and Load: 12,000 RPM (open) with 13.2 kN dynamic and 8.3 kN static load. 2RS rated to 9,500 RPM due to seal lip drag at this diameter.
- Dimensions: 30mm bore x 55mm OD x 13mm width. 12.5mm radial cross-section supports industrial motor, pump, and gearbox loads without excessive housing diameter.
- Temperature Range: -20C to 120C continuous with standard polyurea grease. 150C peak available with high-temperature synthetic grease on OEM request.
- Precision: ABEC-1 standard. ABEC-3 available for tighter bore tolerance and reduced runout. P6 (ISO class 6) on request for electric motor use.

Shielding and Lubrication
The 6006 bearing ships in three sealing configurations. Open bearings suit gearboxes and oil-bath pump housings where system lubrication provides continuous oil flow; this reaches 12,000 RPM. ZZ metal shields use a non-contact labyrinth gap, retaining grease with negligible friction penalty. 2RS nitrile rubber seals form a positive lip contact against moisture and particulate ingress, reducing the speed ceiling to 9,500 RPM due to the larger seal contact circumference at 55mm OD. All sealed variants ship pre-greased for life with polyurea-thickened mineral grease; no field relubrication is required under normal conditions.
At 55mm OD, seal drag becomes a measurable factor in torque budget. The 2RS seal lip circumference at this diameter generates approximately twice the friction torque of the same seal on a 6002 bearing (32mm OD). For continuous-duty motors above 9,500 RPM, ZZ shields eliminate this drag while retaining grease. For agricultural and construction equipment exposed to dust, mud, and pressure washing, specify 2RS regardless of the speed penalty.
Performance
The 6006 bearing carries 13.2 kN dynamic load and 8.3 kN static load at 12,000 RPM in open configuration. Within the 6000-series, it marks the transition from light to medium duty. The 6005 bearing (25x47x12mm, 10.1 kN) serves compact motor frames; the 6006 bearing adds 31 percent more capacity with 5mm larger bore and 8mm larger OD. The 6007 bearing (35x62x14mm, 16.0 kN) gains another 21 percent. For 1 to 7.5 kW motor frames, the 6006 bearing provides load margin a 6005 bearing cannot sustain at full rated torque.
Compared to the 6206 bearing (30x62x16mm, 19.5 kN dynamic), the 6006 bearing saves 7mm OD and 3mm width at 32 percent lower load capacity. When a design team has tooled a housing for 55mm OD, retooling to 62mm for a 6206 bearing means new end bells, gearbox cases, or bearing seats. The 6006 bearing preserves that tooling investment. In conveyor pulley applications where multiple bearings share a common housing bore, the narrower 13mm profile reduces total axial tolerance accumulation compared to the 16mm 6206 bearing.
OEM and Customization
Yuanhe manufactures the 6006 bearing to customer specifications beyond standard catalog items. Common OEM customizations include C3 radial internal clearance for electric motors, C4 clearance for agricultural equipment with wide temperature swings, and high-temperature grease for continuous duty above 120C. Stainless steel (440C) rings and balls are available for food processing and marine environments; note that 440C reduces dynamic load rating to approximately 10.6 kN. Cage options include glass-fiber-reinforced PA66 (standard to 120C), machined brass for high-temperature service, and pressed steel. Snap-ring grooves, extended inner rings, and non-standard bore dimensions are available against drawing review. Standard lead time is 7 to 15 days. Send an existing part number or drawing for a quote.
Applications
IEC-frame electric motors (IEC 112 and 132 series, 2.2 to 7.5 kW), industrial centrifugal and gear pumps, conveyor drive pulleys and idler rolls, light industrial gearbox shafts, agricultural PTO shaft supports and tiller rotors, HVAC air handling unit fan shafts, textile machinery take-up rollers, woodworking planer cutter blocks, small wind turbine main shafts under 5 kW, fitness equipment flywheel assemblies, and hydraulic pump drive shaft supports where the shaft is 30mm and the housing bore is 55mm.
FAQ
Q1: What is the difference between 6006 bearing and 6206 bearing? +
Both have a 30mm bore. The 6006 bearing measures 55mm OD x 13mm width while the 6206 bearing measures 62mm OD x 16mm width. The 6006 bearing is narrower, rated at 13.2 kN dynamic load. The 6206 bearing carries 19.5 kN dynamic load at the cost of 7mm more OD. Choose the 6006 bearing when the housing bore is tooled to 55mm or when weight and axial space matter. Choose the 6206 bearing when load demands the additional 48 percent capacity.
Q2: Can the 6006 bearing replace a 6005 bearing in an existing design? +
Only if the housing bore and shaft diameter are re-machined. The 6005 bearing uses a 25mm bore and 47mm OD, while the 6006 bearing requires 30mm bore and 55mm OD. The 6006 bearing carries 31 percent more dynamic load (13.2 vs 10.1 kN). If the shaft and housing can accommodate the larger dimensions, the upgrade extends fatigue life by approximately 2.2 times for the same applied load. Contact Yuanhe with your load spectrum for a bearing life comparison.
Q3: What is the maximum axial load for a 6006 bearing? +
The 6006 bearing accepts axial loads up to 25 to 30 percent of the unused radial capacity. With a 13.2 kN dynamic radial rating, pure axial capacity under light radial load is approximately 3.3 to 4.0 kN. For sustained axial loading above 2 kN, consider paired mounting or angular contact alternatives.
Q4: What lubrication options does Yuanhe offer for the 6006 bearing? +
Standard fill for sealed variants is polyurea-thickened mineral grease, viscosity approximately 100 cSt at 40C, rated for -20C to 120C. OEM options include low-noise polyurea for electric motor quiet operation, synthetic hydrocarbon grease for extended range (-40C to 150C), fluorinated grease for chemical resistance, and food-grade aluminum-complex grease for food processing. Open bearings ship with a light preservative oil; the end user applies the operating lubricant. Grease fill quantity is 25 to 35 percent of free internal volume.
