FOR EXPLANATION:

6205-2RZ/TN9/HC5/C3/WT

6205: Hybrid bearings have ISO standard dimensions.(DEEP GROOVE BALL BEARING 6000, 6200, 6300 SERIES)

2RZ: Hybrid bearings are available in sealed or open (unsealed) versions. The BHR service assortment includes sealed bearings fittedwith a low-friction seal at each side (-2RZ) or a rubbing seal at each side (-2RS1). The seals are of steel reinforced nitrile rubber,do not conduct electricity and are specially designed to exclude dust efficiently.

TN9: A glass fibre reinforced polyamide 6,6 cage is standard in hybrid bearings having a bore diameter up to and including 45 mm. This lightweight, flexible, high-strength cage performs very well in high speed deep groove ball bearings. 

HC5: Hybrid bearings > 45 mm use a riveted pressed steel cage (no special designation).Silicon nitride balls (Si3N4) impart:

• electrical insulation properties which eliminate the risk of current passing through the bearing;

• excellent high speed capability thanks to low density and low friction;

• minimum wear because of very high hardness;

• extended grease life and reduced risk of seizure. 

C3: Greater than normal radial internal clearance (C3) is standard for the hybrid bearings normally used for electric motor bearings.

WT: grease for wide temperature range (WT) is standard for sealed hybrid bearings and achieves very long lives even at high speeds and high temperature
