/644-Single-Cones-(Imperial)-Dimensions.webp)
The 644 single cones are tapered roller bearings with a 2.8125-inch bore, designed for combined loads. Made from durable chrome steel, they handle dynamic radial loads up to 62,100 lbf and static loads up to 67,000 lbf.
Their open design and steel cage ensure reliable performance, even in temperatures from -30°C to 110°C. The bearings come in standard radial clearance, with options for C3, C4, or C5 if needed.
These cones are interchangeable with Timken models, making them a practical choice for replacements. Ideal for heavy-duty applications like truck axles or industrial gearboxes where combined loads are common.
Compliant with RoHS and REACH standards, they offer a balance of strength and longevity. The ABEC-1 rating ensures consistent performance for most industrial needs.
