Trelleborg product range
Cylindrical and spherical bushes
Supports consist of two concentric cylindrical bushes or a spherical bearing. Natural or synthetic rubber is vulcanized between the metal bushings, allowing “buoyancy” between parts. Some models are capable of working with “cardan deflection” loads.
Types of loads: radial and axial compression, torsion and shear / cardan.
Machine mounts
Conical, V-shaped and machine supports. Some models are of “active safety” which allows the assembly on mobile structures and offer a great resistance to lateral shocks. Others have different stiffnesses according to X, Y or Z directions. There are executions with zinc and phosphated metal surfaces that make them suitable for applications in corrosive environments.
Types of loads: shear, compression.
Cylindrical and conical stoppers
They are the most used elements for vibration isolation. They consist of a conical or cylindrical piece of vulcanized rubber between two plates provided with threaded connections: male – male; female – female and male – female. Versions without a threaded connection are available and are then used as an end stop for shock absorption.
Types of loads for cylindrical stoppers: radial, axial and shear.
Types of loads for conical stoppers: axial.
Conical mounts
Elastic union elements, formed by two conical bushings vulcanized with natural or synthetic rubber. This design allows it to absorb progressive loads in the Z axis and shocks or misalignments in the X, Y axis. Some models are of “active safety”, since in case of deterioration of the support, the motor or machine fixed to it cannot be detached from the structure.
Types of loads: axial and radial.
Instrument mounts
Instrument supports are used to isolate vibrations from electronic components, measuring devices and pressure vessels. The U-shaped supports isolate vibrations and impacts in such a way that the elasticity in the three load directions is different. The O-supports are soft in X, a little more rigid in Y and have maximum stiffness in Z.
Types of loads: compression and shear.
Hydraulic mounts
Supports consist of two concentric conical bushes, vulcanized with natural or synthetic rubber and with an intermediate filling of hydraulic fluid. This support is recommended to isolate low frequencies or when working near the resonance zone. Some models are of “active safety”, since in case of deterioration of the support, the motor or machine fixed to it cannot be detached from the structure.
Types of loads: torsion, axial and radial.
Feet for machines leveling
They are supports that isolate the vibrations of the equipment, at the same time that they allow its leveling being adjustable in height. The base of the element in contact with the floor is usually made of NBR elastomer as it is resistant to contact with oils and hydrocarbons. We can provide articulated units to better adapt to the inclinations of the floor. All stainless steel versions are available.
Types of loads: axial.
Specific designed supports
Supports with different designs to solve different problems. In all of them, the metal components are vulcanized with natural or synthetic rubber.
Types of loads: depending on the solution adopted (compression, torsion, shear).
Cable entry products
Generic name of the range of solutions for the sealing and protection of wiring in the machines installation. In environments with high contamination due to dust, splashes, vibrations or extreme temperatures, Trelleborg’s range of cable entry products solve the traditional problem of wall grommets. Modular, robust designs and easy installation.
