POLYURETHANE TIMING BELTS
TENSION MEMBER ARRANGEMENT
Balanced Tension Member Arrangement for true tracking -
Bifilar Design
The bifilar tension member arrangement is the most
advanced concept in tension member placement. Tension
members with “S” (left-hand lay) and “Z” (right-hand lay) are
used alternatingly to balance the timing belt for true tracking.
BRECO V spliced and welded endless belts and BRECO M
open ended belting are produced in the bifilar tension
member arrangement spaced parallel and symmetrical
across the timing belt width. The tension member diameter
and cable spacing determine the tensile strength which is
appropriate for each timing belt pitch.
BRECOFLEX truly-endless timing belts are manufactured with
two helically wound tension members in the bifilar
arrangement across the entire timing belt width. The result is a
completely continuous uninterrupted timing belt with no
joints. Tracking is greatly improved with the BRECOflex CO.,
L.L.C. truly endless bifilar design compared to standard single
lay tension member designs.

Tension Free Zones
Tension free zones are available with most timing belts. Special
processes allow sections of timing belt widths to be
manufactured with no tension member reinforcement.Tension
free zones allow for very clean vacuum hole perforation,
longitudinal grinding or virtually no tension member
penetration with truly endless BRECOFLEX timing belts.

Sealed Edges
BRECO M open ended and BRECO V spliced and welded
endless timing belts are designed with tension member
arrangements that provide the advantage of sealed edges
for standard belt widths. Special belt widths are possible.
Minimum quantities are required.
Sealed
Edges
Advantages of sealed edges:
• reduce belt edge wear
• prevent pulley damage
• smoother running
• safer operation
