ZIBOO NTN 6819 ZZ Deep Groove Ball Bearings 95x120x13mm

NTN 6819 ZZ Deep Groove Ball Bearings

The ZIBOO NTN 6819 ZZ is a deep groove ball bearing supplied new in a single box. It suits maintenance engineers and electricians who need a direct replacement for worn units in motor shafts or gear assemblies. The sealed ZZ design helps retain lubricant and exclude contaminants during operation.

Dimensions 95x120x13mm

The bearing fits a 95mm bore, a 120mm outside diameter and a 13mm width, so the housing and shaft must match those figures exactly. Axial play and radial clearance follow the standard 6819 series tolerances, which limit misalignment and high-speed capability compared with wider series. No adapter sleeves or shims are included for non-standard seats.

Load capacity and service life

The 6819 size handles moderate radial loads and light axial loads in both directions, making it suitable for electric motor rebuilds and light industrial gearboxes. It runs out of capacity when subjected to heavy shock loads, sustained high speeds beyond the series rating, or misalignment exceeding the internal clearance. For those conditions a larger or higher-capacity series is required.
