• Lubrication: Pre - lubricated with grease , no relubrication needed

Load Ratings & Performance

• Basic dynamic load rating (C): ≈ 5.4 kN

• Basic static load rating (C₀): ≈ 2.36 kN

• Fatigue / endurance load limit (Pᵤ): ≈ 0.10 kN

• Reference (rated) speed: ~ 60,000 rpm

• Limiting (maximum) speed: ~ 30,000 rpm

• Approximate mass: ~ 0.022 - 0.023 kg

Dimensions / Fit Details / Additional Info

• Minimum chamfer / fillet radius on inner/outer ring (r₁, r₂ min): ~ 0.3 mm

• Minimum shaft - shoulder diameter (da,min): ~ 14 mm

• Maximum housing - shoulder diameter (Da,max): ~ 26 mm (typical housing fit clearance)

Characteristics & Typical Applications

• As a shielded deep - groove bearing, 6001-2Z/C3 supports primarily radial loads , and can also carry limited axial loads in both directions.

• The metal shields provide moderate protection from dust/contaminants while allowing low friction and good high-speed capability - more suitable for relatively clean or protected environments (not extremely dirty or wet).

• The increased internal clearance (C3) gives extra room for thermal expansion or shaft/housing deformation under load - useful in applications with temperature variation or slight misalignment.

• With its compact size (12 × 28 × 8 mm), balanced load capacity and high-speed rating, 6001-2Z/C3 is a good fit for small motors , tools , light machinery , appliances , and other mechanical applications where shielded , low-maintenance bearings are desired.
