An MRC 5205M double-row angular contact ball bearing — 25 mm bore, 52 mm outside diameter, 20.6 mm (13/16 in) width, open on both faces. Two rows of balls run on opposed angled raceways inside one pair of rings, so the bearing carries radial load together with thrust in both directions from a single seat. It is the standard choice where a shaft has to be axially located and radially supported without room for a second bearing.
5205 – MRC double-row angular contact ball bearing, 25 mm bore; the same envelope as the ISO 3205 designation
M – machined brass cage
MRC 5200-series nominal contact angle: 30°
No closure suffix, so both faces are open
No clearance suffix, so internal clearance is normal (CN)
A double-row angular contact bearing takes thrust in both directions, which is what lets it replace an opposed pair of single-row bearings and shorten a shaft assembly. The 20.6 mm width is the double-row width; a 6205 deep groove bearing in the same 25 x 52 mm envelope is 15 mm wide and takes far less thrust. The machined brass cage suits higher temperature, higher speed and marginal lubrication better than a pressed steel cage, and it resists cage failure under vibration.
Bore: 25 mm (0.9843 in)
Outside diameter: 52 mm (2.0472 in)
Width: 20.6 mm (13/16 in)
Rows: 2
Contact angle: 30°
Cage: machined brass
Closure: open both faces
Internal clearance: CN
Material: through-hardened bearing steel
Sold as 1 Pc. One complete double-row bearing, open on both faces. No seal ring, shield, snap ring or lock nut is included.
The bearing goes onto a clean shaft seat and mounting force is applied to the ring being fitted, never through the balls. Because the unit locates the shaft axially in both directions, the housing bore should locate it against a shoulder or end cap on both sides. The open faces need grease or oil supplied by the surrounding arrangement.
The direct equivalent is a 3205 double-row angular contact ball bearing from another maker in the same 25 x 52 x 20.6 mm envelope with an open configuration — SKF 3205, FAG 3205B, NSK 3205, Nachi 5205. Sealed and shielded variants (3205-2RS, 5205-2Z, MRC 5205MFF) share the envelope but differ in closure and running friction, so those are related versions rather than drop-in equivalents. A 6205 single-row deep groove bearing is not an interchange.
