The ROLL-RING® is a simpl♣≤€e yet innovative chain tensioner made&•♦ of a specially formulated polymer. Th•↑‍e unique design is based on‌γ a simple toothed ri∏•☆ng that can be installed to≈α♦‌ a horizontal, vertic"©☆"al or diagonal drive in a matter of sec€∞onds, simply by placing σπit between the two strandγ•​s of the chain, it is also s ¶elf-adjusting and maα intenance-free.

When the driver is in u₹♠<se, the ROLL-RING® deforms to an elli&≥©αptical shape due to comp✔♥ ression between the wires and complε₹etely absorbs any slack in the s'$±∞ystem. The ROLL-RING® cγ>♣ ombines a tensioner and a damper int'λ¶‌o one, making it ide✔‍☆↑al for applications where mai' ntenance is difficult or  φ♠Ωimpossible.

advantage

ROLL-RING® chain tens•∏≈ioners provide cost-effective, ✔↕time-saving installation and ma$≈εintenance.

Compared to other types of chain tδ×ensioners, the advantage>Ωs are:

• The ROLL-RING® can be easily instα'¥¥alled where space is l♦↔imited and traditional chain te>✔₹nsioners cannot be used.
• The ROLL-RING® can be installe&™d in just a few seconds.✔λ×
• Freestanding: No sproc©<​kets, bolts, plates, drilling, or exβαpensive installation required
• It can be used without any tools, te ≥¥±nsioning equipment, orσ  any further alignme‍₹<αnt or adjustment.
• It is fully effectiv ​σ☆e in both vertical and diagonal γ>drives.
• The ROLL-RING® works automatically≈γ¥♠, is maintenance-free and self-‌≤↓lubricating.
• Can be used in dusty, >∑dirty environments.
• The ROLL-RING® is a combinatβ&ion of tensioner and damper in >♦×↕one, which reduces n←$→₩oise levels.
• The ROLL-RING® also works in revβ$£¥erse mode.
• ROLL-RING® chain tensioners r×£<educe chain wear and iε£mprove the quality and e₩€‍¶fficiency of the entγ✘ ire chain drive.
