Decoding the designation

209 — bore code in the MRC 200 medium series, giving a 45 mm bore.

S — Conrad-assembly single-row deep groove construction.

ZZ — two rubber seals, one on each face. On MRC this code is elastomer, not metal.

G — snap ring groove machined into the outer ring, with the retaining ring supplied.

What these specs mean in practice

Closure Type: Two rubber contact seals. A lip riding on the inner ring holds the factory grease charge in and keeps dirt and moisture out, which suits shafts in wash-down, dusty or splash conditions where the housing offers no sealing of its own.

Snap Ring Included: Yes. The groove and ring locate the outer ring axially against a plain housing bore, so the bearing is held in position without a shoulder or an end cap machined into the housing.

Internal Clearance: CN. That is the standard radial clearance band, matched to a normal interference fit on the shaft at ambient running temperature.

Mounting data

Shaft seat 45 mm, straight bore. Housing bore 85 mm. Ring width 19 mm. Total Width: 19 mm. That is the standard ISO 62-series medium section for a 45 mm shaft, so the bearing seats in any housing bored for a 6209.

Quantity and configuration

Unit Quantity: 1 Pc. One sealed bearing with its snap ring.
