Fixing Bushings

What are fixing bushings?

The bushes of clamping are a highly significant component of industrial machinery, yet they often do not receive the attention they merit, and their intricacies may not be widely understood. For this reason, we aim to provide further insight into their functions and the benefits they offer.

The bushes of clamping are machine elements upon which shafts are supported and rotate. While this may seem relatively straightforward, it is crucial to recognize that the bushes of clamping can range from a simple component designed to secure a metal cylinder to an intricate assembly of diverse elements. The bushes of clamping are also known as sleeves of clamping, and given their critical importance, they are among the most frequently utilized components for securing bearings with a tapered bore onto a cylindrical seat, a key characteristic being their applicability to both plain and stepped shafts.

Another significant characteristic of  bushes of clamping is their inherent ease of installation, requiring no supplementary fastening mechanisms. They unequivocally represent an optimal solution for motion transmission, effectively augmenting the load-bearing cross-section between the shaft and the motor's transmission system. Furthermore, it is important to highlight another advantage: their capacity to distribute pressure uniformly across the entire surface of the components to which they are coupled.

Regarding the assembly of the bushes of clamping, it is important to note that sequentially tightening the screws will reinforce the two conical sections. This action will, in turn, generate pressure on the two components to be coupled, allowing for their secure fixation in the most appropriate position.

Types of fixing bushings

When selecting between different types of bushes of clamping , it is essential to recognize that various configurations exist, each optimized for superior performance in distinct operational scenarios.

Initially, a distinction must be drawn between the bushes of clamping metric and the bushes of clamping in inches. Both are supplied with a locking nut and a locking device. For smaller sizes, this device is a washer, whereas for larger sizes, it is a retaining element. It is important to note that the bushes of clamping in inches are typically coated with a solvent-free antioxidant.

Furthermore, it is essential to highlight the bushes for injection of oil, which enable the utilization of the oil injection method for the mounting and dismounting of bearings. Additionally, this type of bushes are equipped with oil supply ducts and distribution grooves.

Next on the list are the bushes for bearings of rollers toroidal, which are specifically designed to prevent the clamping device from interfering with the cage. Within this type of bushes, we find the bushes with suffix of designation E, the bushes with suffix of designation L and the bushes with suffix of designation TL.

Finally, we must address the topic of bushes for sealed bearings, which are specifically engineered to prevent the fastening mechanism from interfering with the seals of sealed spherical roller bearings and ball bearings.

Uses of fixing bushings in industry

As previously discussed, the bushes of clamping are crucial components in various types of industrial machinery, and are extensively utilized across numerous sectors in all their configurations.

The bushes of clamping are prevalent in any machinery employing traditional fastening methods such as welding, pins, or conical shafts. Furthermore, it is crucial to emphasize that these bushes of clamping offer superior safety and enable the transmission of higher torques compared to more conventional systems.
