PB Radial Pretensioning Bolts (RPB)

for combined axial and radial pretensioning

The unbeatable combination of all advantages for combined axial and radial pretensioning on large couplings:

– PM Multi-Jackbolt Pretensioners (MJP)

in conjunction with

– Conical Bolt and Conical Split Sleevee

PB Radial Pretensioning Bolts (RVB) are an exclusive development from PLOKE Engineering and are especially suitable for the positive pretensioning of highly dynamic components such as flange couplings or dynamically loaded foundations. They also compensate for misalignments, eliminating the need for time-consuming machining of the flange bores.

Mechanical Radial Pretensioning Bolts (RPB) are used for highest strengths bolting in all areas of industry. Due to the captive mounted Mammoth™ Jackbolts, RPB are best suited for highly dynamic applications such as turbine runners.

  • International PCT Patent Application WO2018/065898
