/3981-Single-Cones-(Imperial)-Dimensions.webp)
The 3981 single cones are imperial-sized tapered roller bearings with a 2.3125″ bore, designed for combined loads. Made from chrome steel, they handle dynamic radial loads up to 31200 lbf and static loads up to 43000 lbf.
Their open design and steel cage ensure durability, while the standard radial clearance allows smooth operation. These bearings work well in temperatures from -30°C to 110°C.
Interchangeable with Timken models, they are 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 reliable performance in demanding conditions. The ABEC-1 rating ensures consistent quality for general industrial use.
