/869-Single-Cones-(Imperial)-Dimensions.webp)
The 869 single cones are tapered roller bearings designed for combined loads, with a 3.4375″ bore and made from durable chrome steel. They handle dynamic radial loads up to 103,000 lbf and operate smoothly in temperatures from -30°C to 110°C.
Their single-row construction and open design make them easy to maintain, while the steel cage ensures reliable performance. The bearings are interchangeable with Timken models, offering flexibility for replacements.
Ideal for heavy-duty applications like industrial gearboxes or axle systems, where combined loads are common. They come in standard radial clearance but are also available in C3, C4, or C5 options for specific needs.
Compliant with RoHS and REACH standards, these cones are a practical choice for engineers and maintenance teams. Their robust design balances strength and longevity in demanding environments.
