The CLASSICA® synchronous belt, being designed with imperial pitch, is a valid and economical altenative solution in low/medium torque transmission systems.
Reduced elongation, no need of lubrication and low wearing makes this belt an economic and reliable option.
TOP DRIVE® HTD belt is an evolution of standard positive drive belts. The tooth shape is the HTD profile according to ISO 13050.
This profile has been used for many years in a wide range of applications and it is well known for its outstanding performances. Power transmission is much higher compared to the classic inch trapezodial profile.
The circular-arc tooth provides superior tooth jump resistance and provides a smooth tooth engagement. The noise level is remarkably reduced if compared to the classic trapezodial belts.
SIT-LOCK® locking assembly unit consists of four pieces with two inside double-one rings joined through a set of tightening screws. It is recomended for medium torques. Although it is not self centering, it can be easily assembled and diassembled.
SIT-LOCK 14 are shrink discs for external, series "14", are characterised by a single tapered ring instead of opposite tapers of the 3 pieces shrink discs SIT-LOCK series "11". The SIT-LOCK 14 Shrink discs offer a better concentricity and centering and very good balancing. These features make the series highly suitable for mid-high speed applications.
SIT-LOCK 14 are manufactured in five different types :
- 14-21 for mid torque transmission
- 14-22 for high torque transmission
- 14-81 for very high torque transmission
- 14-23 eqivalent in size to the type 14-22 but able to transmit an extra 20-30% of torque
- 14-83 eqivalent in size to the type 14-81 but able to transmit an extra 20-30% of torque
TRASCO® ES is our zero backlash coupling designed to compensate for misalignment and vibration dampening for indexing applications. The compact design of TRASCO® ES makes it the right choice for all precise motion applications.
The TRASCO ES consist of two hubs, which are either made of high-strength aluminium (up to the 38/45 size) or steel (from size 42) that are connected with an elastic element.
