Decoding the designation

1900 — MRC ultra-light thin-section series.

19 — bore code, giving a 95 mm bore.

S — Conrad-assembly single-row deep groove ball bearing in MRC’s identification system.

What these specs mean in practice

Bore Diameter: 95 mm. Outside Diameter: 130 mm. Overall Width: 12 mm. Closure Type: Open. Rolling Elements: Ball.

A thin-section bearing puts a 95 mm shaft inside a 130 mm housing bore in a 12 mm wide ring, which is roughly half the section of a standard 6019. That saves weight and radial envelope where the housing is the constraint rather than the load — rotary tables, robot joints, optical and instrument mounts, gimbals. Deep groove geometry takes radial load with a share of thrust in either direction. Open faces let the housing supply grease or oil directly to the raceways.

Mounting data

Straight bore, seated directly on the shaft. Thin-section rings deflect to the shape of what they are clamped to, so bore and housing roundness carry more of the running accuracy than they do on a heavy-section bearing.

Quantity and configuration

Unit Quantity: 2 Pcs. Two complete bearings.

Interchange guidance

The MRC 1900 Type S envelope is an MRC series rather than an ISO one, so the 95 x 130 x 12 mm section does not land on an ISO 60, 61, 69 or 618 number. The direct equivalents are within MRC’s own thin-section range: 1919S is the same bearing under SKF’s MRC Bearing Services line, and the neighbouring sizes are 1918S and 1920S.
