Rubber suspension units

Accessories for tensioning elements and vibration dampers

The simple yet convincing possibility of finding solutions to vibration and damping problems with rubber spring elements has become established in many sectors of mechanical engineering.

The simple handling and ease of installation are highly appreciated, especially in mobile applications. All rubber springs are based on the principle developed by Prof. H. Neidhart. The rubber spring elements can be used in all areas of industry. With a torsion angle of +/- 32° and almost unlimited connection options, they are very suitable for modern, maintenance-free mechanical engineering; all the more reason why the elements usually fulfil multiple functions. Clamping, bearing, springing and damping.

The wide variety of applications for spring elements means that ideas are constantly growing and new fields of application are being developed. The best ideas for alternative applications often come from our customers. We are also happy to work with you to further develop the possible applications and, with our basic range, offer an optimum starting point for sophisticated and sustainable solutions to complex drive problems.

Product overview

Rubber suspension unit type LTA

The inner profile type LTA enables fastening with screws. Up to type LTA 7, through srews of quality 8.8 must be used. From type LTA 8 on, there are threads in the inner profile.

Another simple installation option is the mounting bracket type MA. On the outside, the rubber spring element is inserted into a sleeve tube or fastened with the mounting bracket MS.

Rubber suspension unit type LTS

The inner profile type LTS enables a plug-in connection. The insertion depth of the inserted square should be at least 1.8 times the material cross-section (dimension S). The square should be made of bright steel with tolerance h11 and faceted edges.

On the outside, the element is inserted into a sleeve tube or fastened with the mounting bracket type MS. An alternating deflection over the element zero position is not possible.

Rubber suspension unit type LTC

The inner profile type C enables fastening with central screw. Screws of quality 8.8 must be used.
On the outside, the rubber suspension unit is inserted into a sleeve tube or fastened with the mounting bracket MS. Suitable for alternating deflection up to +/-10°.

Rubber suspension unit type LTB-A

The inner profile type LTB-A allows fastening with screws. Up to type LTB-A 7, screws of quality 8.8 must be used. From type LTB-A 8, there are threads in the inner profile.

Another simple installation option up to size LTB-A 8 is offered by the mounting bracket type MA. The outer housing can be fastened directly with quality 8.8 screws through the fastening holes in the flange section. Suitable for alternating deflection over the element zero position.

Rubber suspension unit type LTB-S

The inner profile type LTB-S enables a plug-in connection. The insertion depth of the inserted square should be at least 1.8 times the material cross-section (dimension S). The square should be made of bright steel with tolerance h11 and faceted edges. The outer housing can be fastened directly with quality 8.8 screws through the fastening holes in the flange section. An alternating defl ection over the element zero position is not possible.

Mounting options

We have the right mounting options for the right rubber spring components. We have various standard components that are available here, which enables very easy and flexible attachment options. Many of our customers use their own fastening concepts and integrate the connecting parts of the spring elements directly into their own units.

mounting bracket type MA

The mounting bracket type MA enables easy mounting of the LTA, LTK-A and LTD-A tensioners at right angles to the base surface.

mounting bracket type MS

The mounting bracket type MS allows easy mounting of the ubber spring elements type LTS, LTA and LTC. The rubber spring element type LT can be freely positioned axially in the mounting bracket type MS before tightening the screws.

mounting bracket type CK

The mounting bracket type CK allows easy mounting of the rubber spring elements type LTK-S, LTK-A and LTK-C. The rubber spring element type LTK can be rotated freely in the mounting bracket type CK before tightening the screws. For this purpose, a hook wrench according to DIN 1810 can be used up to type CK 6 or, in the case of the larger types, a strap wrench.
