LFZB (straight type) LFZF (with flange type) LFZW

Outer diameter chamfer:
When T = 1.0, a0.5
When T = 1.5, a0.8
When T = 2.0, a1.0
When T = 2.5, a0.8

[ M ]Material
: Filler-filled tetrafluoroethylene resin layer, sintered
bronze layer,
steel back metal layer (SPCC: tin plated)
Heat resistance temperature
: -200 to 280°C
[ ! ] Linear and rotational use possible
*1) Chamfering of inner and outer diameters of inner diameters less than d10 is performed to remove burrs and burrs.
2) For inner diameters of d10 or more and plate thickness of 1.0, chamfering is C0.3.

*The housing diameter and shaft diameter are recommended dimensions.
The inner diameter tolerance is a reference value after press-fitting, not a guaranteed value.
[ ! ] Since the LFZB is a wound bushing with a slit, the tolerance of D is a reference value after press-fitting into a ring gauge (±0.002). It is not the outer diameter tolerance before press-fitting.
