Leschuplast Reinforced Slip Spacers

Type B1EG reinforced elastomer point slip spacers

Product description
The type B1EG reinforced elastomer slip spacers are point spacers manufactured of polychloroprene rubber, reinforced with sheet steel. The slip plate is made of stainless steel, and bonded with a PTFE layer it makes up the slip component of a spacer. They are used as bearings for stays, beams, joists, ceilings, for shift values of up to ±20 mm and tension values up to 15 N/mm2.
Note:
A spacer for a shift of up to ±30 mm may be designed.
Thanks to perfect slip material selection for components making up the spacer, the friction coefficient is minimised, while the correct bearing properties are maintained.

Reinforced elastomer slip spacers compensate horizontal supported component shifts through free movements of the slip board over the layer of elastomer with the vulcanised PTFE plate. At the same time, they ensure transfer of loads and  component turning on the support part in line with assumptions; they also reduce roughness of the bearing surfaces.
Type B1EG reinforced elastomer slip spacers are manufactured as square, rectangular or circular pieces, with holes or without holes. Optional openings are made in the elastomer core - a circular opening, in the slip plate an oval opening in line with the shift direction.

Dimensions:

  • thickness t: 14, 18, 23, 25, 32, 34, 39, 45, 56mm
  • thickness d: 10, 14, 19, 21, 28, 30, 35, 41, 52mm
  • side dimensions:

              minimum width b: 140 mm
              minimum length l: 140 mm
              maximum size: 1000 x 1000 mm

Designation:

t - spacer thickness, mm
d – elastomer block thickness, mm 
b – spacer width, mm
l – spacer length, mm
d1- spacer core opening diameter, mm
D - spacer diameter, mm
d2- length of the slip panel oval opening

Note:
The B1EG type spacers are manufactured in any freely selectable size. The minimum size of the elastomer core is 100 mm x 100 mm.

 

Technical and assembly notes

Elastomer spacers must be placed on support components close to the reinforcement bars of the support component.

Reinforced spacers may be used at spots, where dynamic loads may arise.
