CST SERIES COMPACT SLIMLINE BOLT TENSIONERS

CST Series are slimmer, variable type Bolt Tensioners consisting of five parts - Puller, Puller Nut, Load Cell, Bridge & Nut Driver as shown below:

Features

• Versatile Design: Designed to provide a wide range of flexibility, covering stud sizes 3/4” to 2.1/2” (M-20 to M-64).
• High Strength Alloy Steel Construction: All Parts are made from high strength Aircraft Quality alloy steel for long lasting performance and better safety factor.
• Stroke Indication: Marked Piston indicates stroke and provides an over stroke indication.
• Safe Design: Designed to release high pressure hydraulic oil inwards in event of over-stroke, thus saving the operator from exposure.
• Anti Roll, Composite Material Seals: Fitted with Anti Roll, Composite Material seals for longer life and high reliability. The seals used have a low coefficient of friction so that the piston can be returned to a closed position with minimal effort. Sub Sea tensioners can be provided with machined PU (poly urethane) seals if requested by the customer.
• Floating Piston: The unique piston design allows 2º tilt without any loss of load and prevents piston seizure or damage of piston bore.
