TS (Single Row Tapered Roller Bearings) (Imperial) 776-772

The 776-772 is a single-row tapered roller bearing with a 3.75″ bore and 7.125″ outer diameter, crafted from sturdy chrome steel. It handles combined loads up to 77800 lbf radially and 13300 lbf in thrust, making it versatile for heavy-duty use.

Its open design allows for easy lubrication, while the steel cage ensures durability under high stress. The bearing operates smoothly in temperatures ranging from -30°C to 110°C.

This model is interchangeable with Timken bearings, offering a reliable replacement option. Ideal for industrial machinery, gearboxes, or automotive applications where robust performance is needed.

Weighing 11.9 lb, it’s built to last while maintaining precision. Compliant with RoHS and REACH standards for safe and eco-friendly use.

The standard radial clearance can be adjusted to C3, C4, or C5 for specific needs. Its tapered roller design ensures even load distribution, reducing wear over time.

Perfect for setups requiring both radial and thrust load support, such as conveyor systems or heavy equipment. The ABEC-1 rating balances precision and cost-effectiveness for most industrial uses.
