Deep Groove Bearing 6305

The Tritan 6305 2RSL/C3 PRX is a metric radial ball bearing built for rotating equipment that runs in oily or greasy environments. Its 25 mm bore and 62 mm outside diameter fit standard housings using industry number 6305. The double contact seals and Polyrex EM lubricant are factory fitted for contamination resistance.

Contact Seals And Alloy Steel Rings

Both rings and the grade AISI 52100 balls are made from alloy steel with a steel cage, giving a dynamic radial load capacity of 4 640 lbf. The contact seal design retains lubricant and excludes debris during normal operation. ABEC 1 tolerance and a bore tolerance of +0/-0.1 mm provide standard precision for power transmission duties.

Sustained Load In Greasy Conditions

Under continuous load the bearing maintains its rated capacity while the contact seals limit lubricant loss in oily surroundings. The 17 mm outer ring width supports the load across the full complement of steel balls. No retaining ring is included, so axial location must be provided by the housing or shaft design.

Questions about this item

How do I press the 6305 bearing onto a 25 mm shaft without damaging the contact seals?

Support the inner ring only with a sleeve that matches the 25 mm bore and press evenly; forcing the outer ring will crush the contact seals and leak the Polyrex EM grease.

When should I replace the bearing if it runs in oily conditions at the 4,640 lbf dynamic rating?

Replace when vibration or heat rises above baseline; the contact seals and Polyrex EM grease are not serviceable, so the entire unit must be swapped once contamination or fatigue appears.

What is the first limit reached when the bearing runs continuously at the 4,640 lbf dynamic load?

The ABEC 1 tolerance and AISI 52100 balls will generate heat faster than the 17 mm wide rings can dissipate it, making temperature the limiting factor.
