Product Description

The 6217 is an NSK deep groove ball bearing from the 6217 series: 85 mm bore, 150 mm outer diameter, 28 mm width, open type (no shield, no seal). Basic dynamic load rating Cr is 92.5 kN and basic static load rating C0r is 62 kN (NSK official catalog CAT. No. E1103d). Deep groove ball bearings are simple, low-friction and capable of high speeds while carrying both radial and moderate bidirectional axial loads — the most widely used bearing type, common in motors, gear reducers, pumps, fans and general machinery.

FAQ

What's the difference between the Z, ZZ and DDU suffixes?

Z means a single-side steel shield, ZZ means steel shields on both sides, and DDU means contact rubber seals on both sides. Shields suit general environments and high speeds; rubber seals give better dust and water protection with slightly higher friction torque — choose based on your dust exposure and lubrication method.

When should I choose C3 clearance instead of standard clearance?

For motors or other applications with noticeable temperature rise, or high-speed operation, the inner ring expands from heat and reduces the clearance — choose C3 in that case. Standard clearance is fine for general room-temperature, low-speed use. See Nahshon's technical resources for a clearance selection guide.
