Shear Bolt Torque Limiter SB Series for PTO Drive Shafts

The shear bolt torque limiter SB series of Ever-Power Transmission is a device that interrupts power transmission when the transmitted torque exceeds a set value.
This power interruption is caused by the shearing of the bolt. This bolt must be replaced before power can be restored.
The use of a shear bolt torque limiter is recommended to avoid damage to the drive system of a machine mounted on a machine subjected to unexpected overloads or torque peaks.

Shear Bolt Torque Limiter SB Series for PTO Drive Shafts

The shear bolt torque limiter SB series of Ever-Power Transmission is a device that interrupts power transmission when the transmitted torque exceeds a set value.
This power interruption is caused by the shearing of the bolt. This bolt must be replaced before power can be restored.
The use of a shear bolt torque limiter is recommended to avoid damage to the drive system of a machine mounted on a machine subjected to unexpected overloads or torque peaks.

The torque setting of the shear bolt torque limiter is usually double or triple the intermediate torque M and must not exceed the maximum torque of the drive train. The standard settings for each size SFT driveline are shown in the table to the right. SB Torque Limiter sizes S1 through S4 have a pinned attachment to the spline shaft. Larger sizes use a tapered pin attachment.

Note: For operator safety and reliable driveline function, replace only one bolt of the same length, diameter, and grade as the original.

Advantages of Shear Bolt Torque Limiter 

One of the biggest advantages of PTO shear bolt torque limiters is that they protect against overload. They work in a similar way to a 1:1 transmission when the torque is less than a predetermined value. Once the torque exceeds the limit, the limiter acts as a clutch and removes inertial energy from the drive train. They operate in milliseconds, making them suitable for a wide range of applications, including conveyors, assembly lines, textile machinery, and printing machines.

This torque limiter is usually made from hardened steel and is backlash-free. It features additional springs for adjusting the limit. It is available in several models, including pneumatic, hydraulic, and mechanical. It can be installed in a variety of positions, depending on the torque limiter's purpose. During normal use, it does not need to be adjusted. During a malfunction, the user can simply disconnect the auger to restore PTO functionality.

One of the advantages of the shear bolt torque limiters for PTO tractor drive shaft is that they don't waste any energy, allowing you to tow the vehicle. Without this technology, towing would be impossible. Besides, a PTO shear bolt torque limiter is more durable than a manual limiter.

Another major benefit of a PTO shear bolt torque limiter is that it offers a safety measure if a PTO-driven implement jams. A small farm tractor can give up when running at 3800 RPM, and if it suddenly stops, the PTO shaft can also fail. The torque limiting device is the first line of defense against such catastrophic failures, and this slip clutch device eliminates the need to change pins.

Agricultural Gearbox and PTO Shaft

Agricultural gearbox and PTO shaft: These components work together to transfer mechanical power between farm tractors. A PTO shaft converts engine energy into hydraulic pressure. This is what allows the tractor to pull heavy loads. When properly functioning, it reduces the risk of damage to the tractor and to the operator. When used properly, it is an important component of a tractor, but it can also become defective. When choosing an agricultural gearbox, consider the durability and mechanism of the product, as well as its materials. A durable gearbox will last for many years, avoiding repeated replacements. A high-quality agricultural gearbox will be durable for many years to come, and you don't want to end up replacing it for a while. This can be costly, so consider your needs when purchasing an agricultural gearbox and PTO shaft.
