Karver - KBRC Carbon Titanium Blocks
The KBRC blocks are Karver’s most innovative and top performing blocks. The design philosophy behind this range is: an ultra-light weight and compact lashing block capable of handling high loads (up to 40T) with the lowest friction possible (2%). All of the KBR blocks feature titanium sheave and roller bearing as well as ceramic ball bearing for side loads.
The KBRC blocks are made of the most successful features from the other KBR blocks: an ultra-lightweight and compact lashing block capable of handling high loads (1.5 to 40T), with the lowest friction ratio possible (2%). All of the KBR blocks feature titanium sheave and roller bearing as well as ceramic ball bearing for side loads. The KBRC block set themselves apart with carbon side plates for a very modern and racing look.
The KBRC is certainly the most efficient block on the market.
- Used on many racing yachts & super yachts
- Reliable and resistant even under very heavy load Carbon sides
- Titanium sheave for weight and resistance
- Titanium roller bearing and lateral ceramic balls on treated titanium raceways (Karver patent)
- Compact tulip sheaves
- Minimal friction even under very high load (2%)
- Impressive longevity of the bearings (due to the low friction)
- Anti-overturning shape. The pulley remains straight whatever the direction of the effort
- Very generous central space to come and fix several lashings (low runners for example)
- The lashing in the middle is also too big a guarantee of safety. If the pulley breaks (for external reasons of course!) The lashing will still retain the rope while the installation is secure.
- A real design that stands out from other pulleys on the market
- Range from 1.5 T to 40 T. We keep ALL models up to KBRC160 (16T) in stock).
- Available with a leather (KBRCL) or wood (KBRCW) finish – Also available with aluminium (KBR A) or stainless steel (KBR M) sides)
- Delivered without textile shackle
- The blocks are delivered with the bearings lightly greased which has the effect of an impression of significant friction when one tries to make them turn by hand (without load). Our goal is not to have low friction at no load, but very low friction at high loads.
- The 2 flanges are fixed by very tight Dyneema® lashes. It is possible to remove one of its fasteners to allow more open angles.
- In case of opening the KBRC blocks (service/maintenance), make sure to properly tighten the lashing of the flanges as originally set to avoid a slight opening under load that could cause premature bearing wear.
- For complex purchase system assemblies ensure that each block is naturally and freely aligned in its axis. A perfect natural alignment will reduce friction and extend the lifespan of the blocks.
