559 Single Cones (Imperial)

559 Single Cones (Imperial)

The 559 single cones are tapered roller bearings with a 2.5″ bore, designed for combined loads and made from durable chrome steel. They handle dynamic radial loads up to 50,800 lbf and are suitable for temperatures from -30°C to 110°C.

Their open design allows easy maintenance, while the steel cage ensures reliable performance. The bearings come in standard radial clearance, with options for C3, C4, or C5 clearances if needed.

These cones are part of the 555 series and are interchangeable with Timken bearings, making them a practical choice for replacements. Ideal for heavy-duty applications like truck axles or industrial machinery where robust performance is required.

Compliant with RoHS and REACH standards, they offer a balance of strength and longevity. The ABEC-1 rating ensures consistent quality for general industrial use.
