Product Description

What this part is

The MRC 308MFG is a single-row, maximum-capacity filling-notch deep groove ball bearing from the MRC 300-M Medium Series, with one shield and a snap-ring groove in the outer ring. Bore Diameter: 40 mm. Outside Diameter: 90 mm. Overall Width: 23 mm. The filling notch admits a larger ball complement than a Conrad bearing of the same envelope, raising radial capacity.

Decoding the designation

308 — 300 medium series, 40 mm bore.

M — maximum-capacity filling-notch (Max type) construction.

F — one shield; the opposite face is open.

G — snap-ring execution, with a groove in the outer ring for axial location in the housing.

What these specs mean in practice

Dynamic Load Rating: 46,800 N. Static Load Rating: 36,000 N. Limiting Speed: 6,200 rpm grease; 7,500 rpm oil. Closure Type: Shield one side. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. The Max type suits very heavy radial loads, or combined radial and thrust loads where the radial load predominates.

Mounting data

Max Fillet Radius: 1.5 mm (maximum shaft or housing fillet the bearing corner clears).

Quantity and configuration

Unit Quantity: 1 Pc. This piece is supplied without the snap ring fitted.

Interchange guidance

Filling-slot equivalent: NSK BL308ZNR. The Conrad-type 6308-Z/NR shares the 40 x 90 x 23 mm envelope with a smaller ball complement and lower load ratings.
