ZIBOO NTN 6412 ZZ Deep Groove Ball Bearings 60x150x35mm

Industrial Deep-Groove Ball Bearings

The NTN 6412 ZZ units are precision-engineered rolling elements built for electricians and maintenance crews who need reliable radial-load handling in motor, pump or gearbox rebuilds. Each box contains a single bearing pack finished in a red coating for quick visual identification on the bench. The 60 mm inner diameter, 150 mm outer diameter and 35 mm width suit standard metric housings found in industrial power-tool servicing.

Sustained Load Behaviour

Under continuous rotation the double metal shields keep lubricant in and contaminants out, reducing wear during extended duty cycles typical of conveyor drives or compressor shafts. The deep-groove geometry distributes stress evenly across the raceways, limiting temperature rise when the bearing runs at constant speed for long shifts. Shield retention remains secure even when vibration levels increase on ageing equipment.

Dimensional Fit Limits

The fixed 60x150x35 mm envelope dictates housing bore and shaft tolerances; any deviation beyond standard metric fits will cause preload loss or excessive clearance. Axial displacement is not accommodated, so the bearing must be located against a shoulder or snap ring on both inner and outer rings. Users requiring misalignment compensation or higher axial capacity must select a different bearing type.
