![]() ![]() ![]() If the operation sets an internal state flag that was registered with member exceptions, the function throws an exception of member type failure. Multiple flags may be set by a single operation. When set, the integrity of the stream may have been affected. The construction of sentry failed (such as when the stream state was not good before the call).Įrror on stream (such as when this function catches an exception thrown by an internal operation). No character could be peeked because the input sequence has no characters available (end-of-file reached). If there are no more characters to read in the input sequence, or if any internal state flags is set, the function returns the end-of-file value ( EOF), and leaves the proper internal state flags set: The next character in the input sequence, as a value of type int. Then (if good), it reads one character from its associated stream buffer object by calling its member function sgetc, and finally destroys the sentry object before returning.Ĭalling this function sets the value returned by gcount to zero. Internally, the function accesses the input sequence by first constructing a sentry object (with noskipws set to true). If any internal state flags is already set before the call or is set during the call, the function returns the end-of-file value ( EOF). This PEEK bearing modification, TECAPEEK PVX black, was developed for use under high loads and speeds in harsh environments and can also be operated under continuous exposure to hot water or steam.Īs with all Ensinger PEEK materials, we can confirm that our bearing grade TECAPEEK PVX black meets the limitations imposed by RoHS Directive 2011/65/EU Restriction of Hazardous Substances in electrical and electronic equipment.Returns the next character in the input sequence, without extracting it: The character is left as the next character to be extracted from the stream. It can be used dry or with the application of an external lubricant. ![]() At the same time, excellent chemical resistance is maintained. PEEK PVX also offers outstanding tribological performance properties when used with non-metallic mating partners. The tests were carried out on a steel shaft Ø 4mm, at sliding speeds of 0-22 mm/s and a load of 30 N. It also results in thermal conductivity that is three times higher than what we find in standard PEEK natural.įor bearing and sliding applications, the resistance to high PV loads is particularly remarkable.Ī comparison between TECAPEEK natural (unfilled PEEK) and TECAPEEK PVX black (PEEK bearing) also shows the differences relative to the coefficient of friction, depending on the number of cycles and different sliding speeds. In particular, the carbon fibre and graphite fillers in TECAPEEK PVX black help ensure improved thermal conductivity of this PEEK bearing grade. The reinforcement by means of carbon fibre and graphite in low friction PEEK plastic also ensures higher mechanical properties than is normally seen with unfilled PEEK.įurthermore, it is helpful for a PEEK bearing material to have improved thermal conductivity in order to dissipate the frictional heat generated on the component as much as possible, thus avoiding thermal overload or overheating. In addition, a comparatively higher dimensional stability under thermal load is achieved. Compared to all PEEK modifications, TECAPEEK PVX black has the lowest coefficient of friction, and shows higher wear resistance. It combines the properties of a high-grade matrix material with special, wear-improving additives. It is based on a PEEK polymer that has been modified with 10% each of PTFE, graphite and carbon fibres. Created by Boss Design, this modern seating reflects the change towards a. TECAPEEK PVX black was developed especially for bearing and sliding applications. Peek and Boo are a playful duo ideally suited to the contemporary workplace. TECAPEEK PVX black is a modified PEEK material using Victrex® PEEK 450 or Solvay KetaSpire® KT-820 and is classified in the same performance category as Victrex® PEEK™ FC30.
