Timken 2788-3 is a precision tapered roller bearing cone (inner ring) for industrial applications requiring high accuracy. This single cone features a Precision Class 3 (ABEC 5 equivalent) rating, suitable for gearboxes, pump shafts, and machine tool spindles where tight runout control is critical. It is designed for use with a matched cup to form a complete bearing assembly, typically in applications with cup outside diameters under 4 inches.

1/3 Through 5 HP, “A” and “B” Belts

The Econoline Pulley series provides reliable variable speed service with a proven design at an economical cost. The wide selection of models feature compact size and reliability, which make them ideal for both adjustable and fixed center drives in all types of applications using classical “A” and “B” (or 4L and 5L) section drive belts.

Belt Selection

Econoline pulleys are designed specifically for “A” and “B” section drive belts, though they can also be used with “4L” and “5L” belts if necessary. Cogged, raw-edge belts have a definite advantage over wrapped types because they readily form around small pitch diameters, and provide a better arc of contact and provide best possible transmission of torque. If a “slip clutching” effect is desirable to protect machinery in the event of overload, a wrapped belt is recommended.

How do I choose the right type of bearing for my application?

Start with the load and how it’s applied. You need to know if you’re dealing with radial loads, axial loads, or a mix of both. Then look at speed, operating environment, and space constraints. For example, ball bearings are great for high speed and lighter loads, while roller bearings handle heavier loads but usually at lower speeds. If there’s contamination, moisture, or heat involved, you may need sealed bearings or specific materials. In most cases, the right choice comes down to matching load type, speed, and environment to the bearing design.
