Angular Contact Ball Bearing 3306/5306

The Tritan 5306 2RS/C3 PRX is a new angular contact ball bearing designed for power transmission applications. It suits engineers and maintenance teams who need a double-row unit with a 30 mm bore and 72 mm outside diameter. The bearing carries industry numbers 3306 and 5306 for direct replacement identification.

Double Sealed Polyamide Cage Construction

The bearing features a double-sealed closure that retains SRI 2 and Polyrex EM grease while keeping contaminants out. A polyamide cage separates the two rows of alloy steel balls, and both inner and outer rings are made from alloy steel. This construction supports a maximum speed of 7,600 RPM and an operating temperature range from -40 to 175 degrees Celsius.

Verify Shaft and Housing Fits Before Ordering

Confirm that your shaft diameter matches the 30 mm bore and that the housing can accommodate the 72 mm outside diameter with a 30.2 mm overall width. The bearing is supplied as a single, unmatched unit, so it is not intended for paired mounting arrangements. Check that the speed and temperature limits suit your application requirements.

Questions about this item

What does the 7,600 RPM maximum speed mean for continuous operation?

The bearing is rated for up to 7,600 RPM under proper lubrication with SRI 2 or Polyrex EM grease. Exceeding this limit can cause overheating and premature wear of the alloy steel balls and polyamide cage.

What shaft and housing tolerances suit the 30 mm bore and 72 mm outside diameter?

The 30 mm bore requires a shaft tolerance such as h5 or h6 for a secure interference fit. The 72 mm outside diameter typically pairs with an H7 or H8 housing bore to prevent rotation of the outer ring.

How do I install this double-sealed angular contact bearing without damaging the seals?

Press only the inner ring onto the shaft and only the outer ring into the housing using a sleeve or driver that contacts the ring face evenly. Never apply force through the rolling elements or the polyamide cage, and keep the double seals free from sharp tools.
