TRITAN 5205 Angular Contact Bearing

The TRITAN 5205 2RS/C3 PRX is a new, double-row angular contact ball bearing designed for precision rotational applications. It suits engineers and maintenance teams who need a single, pre-sealed unit with a 25 mm bore and 52 mm outside diameter. The polyamide cage and alloy steel rings deliver consistent performance in power transmission equipment.

Upgrading From Single-Row Or Open Bearings

This two-row design replaces single-row bearings where higher axial load capacity in both directions is required. The jump is worth it when an application demands the combined radial and thrust capability of a matched pair without the complexity of mounting two separate units. It is not for buyers who need a self-aligning bearing or a unit pre-matched for tandem mounting.

Limits Of The Double-Sealed Grease Fill

The factory SRI 2 and Polyrex EM grease fill operates between -40 °C and 175 °C with a maximum speed of 9,800 RPM. The double seals retain lubricant but prevent relubrication, so service life is fixed by the grease condition. Builders who require oil lubrication, higher speeds or continuous relubrication intervals must select an open or shielded alternative.

Questions about this item

What shaft diameter does the 25 mm bore of this angular contact bearing fit?

The 25 mm bore is designed for a 25 mm shaft; the outside diameter is 52 mm and the overall width is 20.6 mm, so verify your housing can accommodate those dimensions.

How do I press-fit this double-sealed bearing without damaging the polyamide cage or the SRI 2 / Polyrex EM grease fill?

Apply even pressure only to the inner ring when mounting on the shaft and only to the outer ring when seating in the housing; never strike the seals or cage, and keep the bearing clean to avoid contaminating the factory grease.

When should I replace this bearing given its 9,800 RPM speed rating and -40 °C to 175 °C operating range?

Replace it if you detect abnormal noise, vibration, excessive heat, seal wear or grease leakage; the double seals and factory grease are not user-serviceable, so the whole unit must be swapped once any of those signs appear.
