Neoprene Synthetic Elastomeric Bearing Pads
Neoprene Synthetic Elastomeric Bearing Pads can be used for bridges, viaducts, buildings, storage tanks, sealing elements, isolation, etc.
Neoprene Synthetic Elastomeric Bearing Pads are made of an elastomer containing neoprene (polychloroprene) as the base polymer. Neoprene Synthetic Elastomeric Bearing Pads are available primarily in 55 durometer hardness (Shore A) and meet the CAN/CSA-S6-06 standard, or in hardness meeting Ontario OPSS 1202. Neoprene Synthetic Elastomeric Bearing Pads are available in roll form, sheet form or cut to specific bearing pad sizes with or without holes or slots.
Elastomeric Bearing Pad Manufacturing in Canada
Benchmark can cut our Elastomeric Bearing Pads to any shape you require including rectangle, circles, squares etc. We can also cut holes and slots into the Elastomeric Bearing Pads as required or we can bond the bearing pad materials to carbon steel or stainless steel.

Benchmark accepts no responsibility for individual results obtained. Everyone is strongly recommended to verify data and obtain their own independent test results. This data is subject to change without notice.
Elastomeric Bearing Shape Factor Considerations:
Elastomeric Bearing Shape Factor (S):
The behavior / deflection of an elastomeric bearing under compression is influenced by the shape factor (S), which is defined as the ratio between the loaded area of the bearing and the area which is free to bulge / deflect.
SF = Loaded Area / Bulge Area
SLS = Serviceability Limit State
ULS = Ultimate Limit State
Maximum pressure under permanent load = 4.5 MPa (SLS), 7.0 MPa (ULS)
Maximum pressure under total load = 7.0 MPA (SLS), 10.0 MPa (ULS)
Maximum Shear Deformation of Elastomeric Bearing Pads:
Maximum shear deformation of a plain elastomeric bearing pad is limited to 50% of the total pad thickness.
