MOTORS & DRIVES & CONTROLS
Sovereign wear-resistant chain and the Timken Quick- Flex couplings. The Gates Quad-Power 4 V-belt is designed to
off er a way to cut back on belt replacements and deliver a higher performance. It is the fi rst bandless, no-maintenance V-belt. Its new generation EPDM rubber compound provides a long service life and a wear-resistant belt under extreme temperatures from -50°C to 130°C. It features minimal-elongation polyester tensile cords for stable tension over the entire lifetime. It also has a blue adhesion layer for an extra strong bonding of the tensile cords and the rubber compound. Meanwhile, the next generation of Red Power
3 V-belts from Optibelt off er up to 50% more performance, while at the same time cut costs by up to 35%. Providing a maintenance-free option, the V-belt maintains optimum tension throughout its service life and has an increased temperature range from -40°C to 100°C, as well as increased life due to dual wrap. It is also shock resistant and energy effi cient.
LUBE-FREE ROLLER CHAIN Tsubaki’s Lambda chains were the fi rst to use a special oil-impregnated bush, making them ‘lube-free’. The company’s new BS Lambda chain, can be disassembled quickly and safely without damaging the bushes and has excellent performance in temperatures up to 150°C.
Benefi ts include cost savings on maintenance, reduced labour costs and overall purchasing cost savings due to its overall lifetime value and lower frequency of replacements. The new Renold Sovereign chain includes a surface
treatment that greatly increases wear resistance, making it suitable for aggregates, agriculture and construction. It is ideal for restricted maintenance situations and suitable for high speed or heavy load applications. Off ering resilient and durable components, its lifetime wear is up to four times longer than lower quality chains in harsh environments, providing excellent reliability and contributing to reduced maintenance costs. Designed for high and low torques as well as variable
speeds, Timken Quick-Flex couplings can handle tough challenges with little or no maintenance. Easy-to-install and requiring no lubrication, their lifespans match those of rotating equipment to help keep the overall cost of ownership low. They off er effi ciency, through the easy replacement of urethane inserts without the need of removing the hubs and durability, as the design can eliminate the interference between coupling hubs and can withstand up to two degrees of misalignment. ●
