Precision Radial Bearing 6209

The Tritan 6209 ZZ/C3 PRX is a metric radial ball bearing built for rotating equipment that runs in oily or greasy environments. Its 45 mm bore and 85 mm outside diameter fit standard housings specified by industry number 6209. Maintenance teams and OEMs use it to replace worn units in conveyors, gearboxes and electric motors.

Double Shielded Steel Cage

Twin metal shields keep lubricant in and coarse contaminants out while the steel cage maintains ball spacing at speed. The Polyrex EM grease fill suits high-temperature operation and the ABEC 1 tolerance class delivers standard running accuracy. Alloy steel rings and AISI 52100 balls rated at 7,300 lbf dynamic capacity handle heavy radial loads without excessive heat or noise.

Direct 6209 Replacement

This bearing matches the 6209 envelope exactly, so it drops into existing bores and housings without machining changes. The jump is worth it when the original unit shows shield damage, grease breakdown or raceway wear that raises vibration. Buyers needing a sealed variant or a higher ABEC class for precision spindle work should look elsewhere.

Questions about this item

How do I press the 6209 bearing onto a 45 mm shaft without damaging the double shields?

Use a press tool that contacts only the inner ring; pushing on the outer ring or shields will dent the steel cages and ruin the Polyrex EM lubricant film.

When should I replace the bearing if it runs in an oily environment at the 7 300 lbf dynamic rating?

Plan replacement once vibration or temperature rise signals raceway fatigue; the AISI 52100 balls and alloy-steel rings have no user-serviceable lubrication interval.

What is the first limit reached when the 6209 runs continuously at full 7 300 lbf radial load?

The ABEC 1 tolerance band and +0/-0.012 mm bore fit allow enough internal clearance for heat growth, so material fatigue in the alloy-steel races appears before clearance loss.
