 Timing
Belts are a superior alternative
to V-belts, Roller Chains and
Gears in an amazing number of
applications. Embekon Engineers
deals in the entire range of
Rubber and Poly-Urethane (PU)
Timing Belts in standard and
special widths and lengths. We
stock Timing Belts of globally
renowned brands thereby
maintaining our focus on quality
and ensuring customer
satisfaction. The following are
the various types and dimensions
of Timing belts available in
both Rubber and Poly-Urethane. |

Synchro Power
Timing Belts |
|
A synchronous
timing belt is a toothed belt,
usually of reinforced rubber /
poly-urethane that meshes with
the grooves of a pulley in a
synchronous belt drive. It
usually drives the camshaft in
an internal combustion engine.
These belt drives, unlike flat
and V-belt drives are positive
and maintain constant speed
during power transmission,
thereby avoiding slippage.
Synchronous Belts have a
trapezoidal tooth profile. These
belts are based on imperial
(inch) as well as metric (mm)
pitch sizes. |

High Torque Drive
(“HTD”) Timing Belts |
|
HTD timing
belts are metric curvilinear
tooth form synchronous belts for
low speed high torque drives.
HTD belts have a curvilinear
tooth form giving a more uniform
distribution of shear stresses
within the teeth and a
transition of tooth loads to the
tensile members in the belt
which significantly improves
upon classical Timing Belts.
These belts are based on the
metric (mm) pitch sizes: |

Twin Tooth Timing
Belts |
|
  These
distinctive Timing Belts are
recommended for synchronized
serpentine drives where load
transmission is required on both
sides of the belt. It eliminates
the noisy oily chain drives and
offers a long virtually trouble
free service in wide horsepower
range. They are specified the
same way as timing belts except
with a "D" prefix. Double sided
timing belts are available in
the following series: DXL, DL,
DH, DT5 and DT10. Open ended
belts in some of these series
available on request. |
