Sentence examples for hard bearing from inspiring English sources

The results indicate that lower contact pressures may be achieved using a soft layer, compared to conventional disc arthroplasty devices that have hard against hard bearing surfaces.

As a specific example, the introduction of two-nanometre aluminum oxide precipitates into thin films of pure nickel results in yield strengths increasing from 0.15 to 5 gigapascals, which is more than twice that for a hard bearing steel.

The samples were subjected to dry sliding wear tests against hard bearing steel balls (SAE 52100 steel) and softer mild steel pins (AISI 1018 steel) at different sliding speeds and contact loads.

Advantages on wear can be counterbalanced by the use of hard bearing surfaces or highly cross linked polyethylene liners, besides the availability of larger femoral heads improving implant stability further reduces the importance of femoral offset restoration by means of modularity.

As a result, there has been a renewal of interest in hard bearing surfaces for total joint arthroplasty, including both metal-on-metal and ceramic-on-ceramic components.

There is little evidence for any clinical benefit of using hard bearing materials.

Implant survival will be aided by reduced wear rates, either through design and material changes to the bearing on polyethylene or in the use of hard on hard bearings.

The performance of hard bearings is dependent on component positioning.

Following their analysis of the literature, Sedrakyan et al. (2011) found that there were no benefits of using hard bearings instead of PE bearings.

We have started using hard bearings in our younger patients: ceramic-ceramic for females and metal-metal for males, which will hopefully be a better solution than polyethylene.

These problems drove the development of cementless implants; larger, more anatomical head sizes; and hard bearings (Lord et al. 1979, Sedel et al. 1990, Cuckler et al. 2004, Delaunay et al. 2008).
