Outside Diameter: 52 mm. Overall Width: 15 mm. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Closure Type: Shields both sides. Cage Material: Pressed steel. Cage Type: Pressed, ball-guided. Bearing Material: Chrome steel. Internal Clearance: CN. Precision Class: ABEC 1 / P0. Series: ISO 62 light.

Decoding the designation

6205 — the ISO 62 light series at bore code 05, giving a 25 mm bore in a 52 mm housing.

S — Conrad-assembly deep groove, non-filling-notch, so both raceway shoulders are unbroken.

FF — two metal shields. On MRC, F and FF are shields and Z and ZZ are rubber seals, which is the reverse of the NSK, SKF and FAG convention.

G — snap ring groove machined in the outer ring, with the snap ring supplied in it. That is the NR execution in ISO nomenclature.

What these specs mean in practice

Dynamic Load Rating: 14,800 N. Static Load Rating: 7,800 N. The dynamic figure sets rating life under rotation; the static figure sets the load the raceways carry at rest or under shock without permanent indentation.

Metal shields run with a small clearance at the inner ring land rather than rubbing on it, so they add almost no running torque and cost the bearing very little speed. They hold the grease charge in and keep coarse contamination out.

The snap ring locates the outer ring axially in a plain, unshouldered housing bore. A through-bored motor endbell or a fabricated housing can then hold the bearing without a machined step.

Internal Clearance: CN. Standard radial clearance. Precision Class: ABEC 1 / P0, standard annular tolerance.

Mounting data

Bore Type: Straight, 25 mm shaft seat. Housing bore 52 mm. Width across the rings 15 mm. Outer ring located axially by the snap ring in its own groove.

Quantity and configuration

Unit Quantity: 10 Pcs. Ten individual bearings, each shielded both sides with its snap ring fitted, supplied as one lot.

Interchange guidance

The 6205 boundary envelope is an ISO standard, so the shielded snap-ring equivalents below share bore, outside diameter and width exactly and interchange in the same housing bore and shaft seat. Searchable variants of the number: 6205SFFG, 6205-S-FF-G, 6205 S FF G, 6205-ZZ-NR, 6205-2Z-NR.
