TSBF-C TSBR-C Self centering Floating jaws Self centering Rigid jaws
High precision pull-down chuck Ø 220 - 330 mm
■ Active pull-down ■ Tongue & groove ■ Large through-hole ■ 3 jaws
Application/customer benefits • Clamping of workpieces with highest demand for parallelism • Highest productivity with long maintenance intervals • Constant gripping force and long lifetime ensure constant quality of workpieces • Through-hole to insert long workpieces or for special clamping applications TSBF-C: Floating base jaws to clamp raw and easy deformed workpieces (6-point-contact) TSBR-C: Rigid base jaws for precise clamping on pre machined diameters Technical features • Active pull-down • Permanent grease lubrication • Centrifugal force compensation • Large through-hole • TONGUE & GROOVE base jaws • proofline ® chucks = fully sealed - low maintenance Standard equipment Ordering example 3-jaw chuck 3-jaw chuck TSBF-C 220 / A6 Mounting bolts or 3-jaw chuck TSBR-C 330 / Z300

■ Use of the larger space between the master jaws for bulky parts.
■ Use of the bore for shaft or special locators or centering equipment.
Principle of function: ■ 1 pre-clamping - 2 active pull-down - 3 clamping ■ For O.D. and I.D. clamping.
TSBF-C
TSBR-C
TSBF-C: Floating jaws for clamping raw / easy deformed workpieces with 6-point-contact.
TSBR-C: Rigid jaws for precise clamping on premachined diameters with 3-point-contact.
■ TSBF-C and TSBR-C chucks operated with a SIN-S cylinder with central bore for air sensing / coolant flush.
