Angular Contact Ball Bearing

The Tritan 5208 ZZ/C3 PRX is an angular contact ball bearing designed for applications that require combined radial and axial load support. It suits maintenance teams, machinery builders and industrial equipment operators who need a precision rolling element for pumps, gearboxes or electric motors. The double-shielded closure helps retain lubricant and exclude contaminants in demanding environments.

Bore Diameter 40 mm Outside Diameter 80 mm Width

The single specification that decides fitment is the bearing geometry: a 40 mm bore, 80 mm outside diameter and 30.2 mm overall width matching industry numbers 3208 and 5208. Buyers must verify these three dimensions against the housing and shaft seats before ordering, as no other size variants are described in the data.

Sustained Operation Up To 6 600 RPM And 175 °C

Under continuous load the bearing is rated for a maximum speed of 6 600 RPM and a maximum operating temperature of 175 °C, with a polyamide cage and SRI 2 Polyrex EM grease fill. The alloy steel rings and balls maintain structural integrity at the upper thermal limit, while the double shields preserve grease life during extended duty cycles. The minimum operating temperature is -40 °C.

Questions about this item

What does the 6 600 RPM speed rating mean once the bearing is installed?

The 6 600 RPM figure is the manufacturer's maximum permissible rotational speed for this angular contact bearing under standard operating conditions. Actual running speed in your machine will depend on load, lubrication condition, alignment, and temperature. Exceeding this limit can cause overheating and premature failure.

What does the double-shielded closure cap in practice?

The double-shielded (ZZ) closure uses metal shields on both sides to retain the factory-filled SRI 2 and Polyrex EM greases while excluding larger contaminants. It is not a contact seal, so fine dust or liquids can still enter, and the shields do not increase the 6 600 RPM speed limit.

What shaft and housing dimensions are needed to mount this 40 mm bore, 80 mm OD bearing?

The bearing requires a 40 mm shaft seat and an 80 mm housing bore. The overall width is 30.2 mm, so the housing must provide at least that much axial space. Proper fit tolerances for the shaft and housing should follow standard angular contact bearing mounting practices for the intended load and speed.
