THE EXCEPTIONAL DURABILITY OF PULLERS " is ensured by
choice materials with accessories and with the additional
hardening of exposed parts.
ADDITIONAL PRECISION " as the tip attached to the spindle
allows for precise pulling without slippage.
VARIETY " made possible by a product line that features a
variety of pullers for extracting bearings, bearing rings, pulleys
and joints, as well as for other intended uses.
Premium Flex Plus Carbon Steel
E"ciency and durability under considerable
crushing and deformation stress
Construction and trade steels have special properties that guarantee
their appropriate hardness, ductility and elasticity, as is required for
tools such as setters, hammers and screw clamps, which are exposed
to great force during hammering and clamping. Steels with a medium
carbon content that are used to make tools have a higher carbon
content, resulting in better durability. A suitable manganese content
increases the tensile strength and ductility of the material, which is
particularly important under high load conditions. The chrome content
reduces the susceptibility to cracking, while the silicon content
increases the elasticity of tool materials subjected to strong forces.
Medium carbon steel C45R, according to EU directive
2000/53/EC and the EN 10083-2 standards:
› 0,45% carbon for higher tensile strength and better tempering
› 0,70% manganese for higher tensile strength and ductility
› 0,35% chrome for higher tensile strength and lower susceptibility to
cracking
› 0,20% silicon for higher elasticity
