Precision Angular Bearing for High-Speed

The Tritan 5203 ZZ/C3 PRX is a double-shielded angular contact ball bearing designed for precision machinery requiring accurate axial load handling. Its 17 mm bore and 40 mm outside diameter suit standard housings in motors, pumps and spindles where rigid radial and thrust capacity are needed. The polyamide cage and alloy steel rings deliver smooth operation in new equipment builds or as direct replacements for industry numbers 3203 and 5203.

Speed and Temperature Envelope

Factory-filled with SRI 2 and Polyrex EM grease, the bearing operates continuously from minus 40 to 175 degrees Celsius without relubrication. The double shields retain lubricant while excluding contamination, supporting a maximum rated speed of 13 000 RPM for the two-row assembly. Engineers must verify that the application shaft speed and thermal environment remain within these published limits to avoid premature wear or cage deformation.

Load Capacity and Operational Headroom

The angular contact geometry and two-row construction provide substantial combined radial and axial load capacity for its 17.5 mm width, handling typical spindle and gearbox duties with reserve. Single-row or matched-pair arrangements are not represented by this unit, so designs requiring paired preload or higher moment stiffness will need a different configuration. The unmatched, single-bearing supply simplifies inventory for maintenance crews replacing one unit at a time.

Questions about this item

Which bore size and industry number match this TRITAN angular contact bearing?

This bearing has a 17 mm bore and carries industry number 3203/5203, so choose it when your shaft is 17 mm and the housing calls for that number.

What does the 13 000 RPM rating mean once the bearing is installed?

It is the maximum speed the bearing can sustain with its SRI 2 and Polyrex EM grease; actual operating speed will be lower depending on load, alignment and lubrication condition.

How does the double-shielded closure affect contamination protection and speed limit?

The double shields keep debris out while retaining the factory grease, and the 13 000 RPM limit already accounts for this shielded design.
