Boltite BT Series
1.Misalignment Compensation ① –
The unique floating piston design allows a 30 tilt (in any direction) without loss of load, preventing piston seizure or damage to the cylinder bore.
2.Piston Stroke Indicator ②
The integral piston stroke indicator allows piston stroke to be viewed, measured and controlled.
3.Seals ③
Low friction, anti-roll/non-spiraling seals and rigid back-up rings are incorporated within a unique piston/cylinder design for improved life and reliability.
4.Conventional Adaptor Kit ④ ⑤ ⑦
The interchangeability of adaptor kits, including bridges, nut rotating disc and puller sleeve, enables a number of different bolt sizes to be tensioned using a single load cell. Boltite offers maximum economy and versatility by the conventional adaptor kits.
5.Nut Rotating Disc ⑦
A range of nut rotating discs are incorporated to eliminate the need for, and preparation of pre-drilled nuts.
6.Dual port design ⑧
The Boltite tensioner with dual ports offer the tightening bolts connections simultaneously without tee-block, allows two time faster operation than single port tensioner.
