PTFE Sliding Bearing Rattle Testing
- 50 Hz sine wave excitation at 40 ms-2 acceleration
- 0.2 mm clearance
- all values shown are dB(A) and are the average of 5 tests each
NORGLIDE® Bearings provide superior vibration dampening properties which reduce the risk of irritating rattling noises.
View the videos below to hear how four competing bearings with PTFE sliding layers compare with three different NORGLIDE® materials.
Competitor Bearing 1
Steel backing.
Layer of porous sintered bronze is fused to the steel backing. Sliding surface is PTFE with filler.
Competitor Bearing 2
Steel alloyed backing.
Layer of porous sintered bronze is fused to the steel backing. Sliding surface is PTFE with filler.
Competitor Bearing 3
Steel backing.
Layer of porous sintered bronze is fused to the steel backing. Sliding surface is PTFE with filler.
Competitor Bearing 4
Steel alloyed backing.
Layer of porous sintered bronze is fused to the steel backing. Sliding surface is PTFE with filler.
