/749-Single-Cones-(Imperial)-Dimensions.webp)
The 749 single cones are tapered roller bearings designed for combined loads, with a 3.3475-inch bore and made from durable chrome steel. They handle dynamic radial loads up to 84,700 lbf and operate smoothly in temperatures from -30°C to 110°C.
Their open design and steel cage ensure easy maintenance and long service life. The bearings come in standard radial clearance but are also available in C3, C4, or C5 options for different needs.
These cones are interchangeable with Timken models, making them a reliable 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 performance for demanding environments. The ABEC-1 rating ensures consistent quality for most industrial uses.
