POWER TRANSMISSIONTensioners/Sprockets/Pulleys


Considered to be one of the leading manufacturers of high performance drive belts, the Amtz Optibelt Group products are used where durability and quality are required.

High quality craftsmanship is not a matter of chance, the company is family owned employing 1,900 personnel worldwide. They have 8 production locations in 6 countries, all with the same strict quality code. Being a family business, Optibelt think in terms of generations rather than in terms of quarters and years. They have a principled philosophy, being innovative but not experimental at the expense of their quality ratings. Optibelt has a proven place on the world market as a strong and respected brand.

Optibelt products are extremely versatile and used in many industries; agricultural technology, paper and cement industries and in general machinery. Ranging from the robust Krafbands for agricultural machinery, high performance V-belts in road construction to precision timing belts for the food industry.

Longer Belt Life in Harsh Operating Conditions

HPC Belting is manufactured from high performance polyurethane/polyester composite materials which ensure excellent durability even in the most demanding conditions. HPC Belts from Fenner Drives will outperform conventional rubber belts in handling hostile environments, including exposure to oil, grease, water and most common industrial and agricultural chemicals and solvents. They are also more resistant to abrasion and will operate, with no loss in performance, at a more extreme temperature range - from -40°C to 116°C (-40°F to 240°F).

Reduced Belt Stock - Any Belt, Any Time

With PowerTwist Plus, NuTLink and SuperTLink, there's no need to maintain inventory of numerous different endless rubber belts to cover all your drives. Carry a pack each of A/13 and B/17 in stock and you're almost 100% covered with a significant reduction in working capital tied up in spares.

Easier and Faster Installation

Unique "quick connect" belt designs provide for easier and faster belt installation, even on captured or restricted access drives - no tools required. Belts are easily made up to the required length, by hand, in seconds and can be rolled onto a drive just like a bicycle chain. No need to dismantle drive components or change existing pulleys as HPC Belts run in industry standard pulley grooves.

Minimized Maintenance Time

Like all power transmission belts, Fenner Drives HPC Belts may require retensioning after an initial "run in" period. But unlike conventional belts, with PowerTwist Plus, NuTLink and SuperTLink, retensioning is simple; just roll the belt off, take out a link and roll it back on - no need to move any drive components. No time - no trouble.

Simplified Drive Design

The unique "quick connect" design of the Classical and SP rated composite belts allow designers considerable freedom in their choice of optimum drive configuration and placement with resultant savings in component costs and assembly times.

As PowerTwist Plus, NuTLink and SuperTLink are effectively self-tensioning on installation and exhibit low operational stretch; there is no need to incorporate belt tensioners and sliding motor bases into drive designs. Additionally, drives can be optimally mounted on/in equipment where such positioning would be impossible with conventional belts when considering ease of subsequent field maintenance. Plus, Fenner Drives composite belts can be used on misaligned or angled pulleys up to 17.5 degrees without significant reduction in belt life.

Reduced Drive Vibration & System Noise

PowerTwist Plus, NuTLink and SuperTLink do not have the continuous tension cords found in conventional endless belts. As a result, transmitted vibration in the drive system can be reduced by 50% or more. Consequently, system noise is reduced and, as a bonus, bearing life extended.

The link construction means that belts can be fitted easily and quickly even on inaccessible drives. Belts can be joined around the shafts without dismantling the drive.
