NDH7119Deep Groove Ball Bearing 10x26x8 mm, One Steel Shield with Opposite Face Open, 6000 Envelope, Set of 7 Pcs

Product Description

What this part is

An NDH 7119 single-row deep groove ball bearing — 10 mm bore, 26 mm outside diameter, 8 mm width — with one steel shield fitted and the opposite face open. This is the 6000 envelope, the standard small-shaft radial bearing used in fractional horsepower motors, fans, instrument drives and light gearheads. New Departure Hyatt was the bearing division of General Motors.

Decoding the designation

7119 – NDH catalogue number for the 6000 envelope: 10 mm bore, 26 mm OD, 8 mm width
Single shield – one steel shield, opposite face open. A single Z denotes one shield; a double shield would be marked ZZ or 2Z
No clearance suffix, so internal clearance is normal (CN)

What these specs mean in practice

A steel shield is non-contact: it runs with a small clearance at the inner ring land, so it keeps coarse debris out and holds grease in without adding rubbing friction or limiting speed. With a shield on one face only, the open face still lets lubricant in from the housing cavity, which is why this configuration is common where the bearing sits against a gear or oil-fed cavity on one side and needs protection on the other. Orientation therefore matters: the shield faces the contamination or the outside of the machine.

Quantity and configuration

Sold as a set of 7 Pcs. Seven individual bearings, each with one shield and one open face. No snap rings, seals or spacers are included.

Fitting notes

Mounting force is applied to the ring being fitted so that no load passes through the balls, and the shield is not a press surface. The bearing is fitted with the shield toward the side needing protection and the open face toward the lubricant supply.

Interchange guidance

The direct equivalent is a single-shielded 6000 in the 10 x 26 x 8 mm envelope: SKF 6000-Z, FAG 6000-Z, NSK 6000Z, NTN 6000ZZ single-shield equivalent 6000LB, Koyo 6000Z. A double-shielded 6000-2Z or 6000ZZ and a sealed 6000-2RS share the envelope but close both faces, so those are related versions rather than equivalents where the open face is needed for lubrication. An open 6000 offers no shielding at all.
