SBT - Spring return topside bolt tensioner - Imperial range

Featured Brand: Hi-Force  

The SBT imperial spring return bolt tensioners have all of the qualities and advantages of our standard STS range, with the added benefit of a spring assisted return hydraulic pistons. Designed mainly for topside operation, the spring return feature will reduce bolt tensioning cycle times significantly. This is due to fact that tensioner pistons will immediately start to retract, following the release of hydraulic pressure. This range consists of 22 models suitable for standard size bolts from 11/4” to 4” diameter. The flexibility of the SBT bolt tensioner is similar to our standard STS models with various exchangeable threaded pullers and nut rotating sockets which are offered either as bolt size conversion kits or individual parts. For more information, please check on SBT imperial conversion kits. All SBT bolt tensioners operates at maximum pressures up to 1,500 Bar and are designed with a wear coated piston, maximum stroke indicator, self energizing high pressure seals, dual quick connect couplers for quick multiple tensioner hook up.
