Why Choose Howcroft for Renold
Renold is a name most plant engineers know from their own apprenticeship, and we have supplied it for decades.
Chain is a system, not a part number: pitch, strength, sprocket wear and lubrication together decide how long a drive lasts. We quote the complete drive and help identify a chain from a pitch, a broken link or a photograph.
Chain specification
Standard and heavy duty chain, sprockets, attachments and tensioners specified together.
Sprocket and drive matching
Advice on tooth counts, alignment and lubrication that stops premature wear.
Long-standing supply
A brand our team has handled for years, with fast identification of older and obsolete parts.
RENOLD
The World's Best Transmission Chain
Since 1879, Renold has defined the global standard for precision roller chain and gearbox engineering. From the first-ever standardised roller chain (BS, ANSI) to today's aerospace-grade nickel-alloy variants, Renold remains the technical benchmark for industries where transmission failure is not an option.
Three Technical Reasons to Choose RENOLD
Proven engineering superiority backed by measurable performance data
Syno & Synergy Chain Precision
Laser-measured pitch accuracy to ±0.08mm (3x tighter than ISO 606) eliminates polygon effect and premature sprocket wear in high-speed conveyors.
Renold Gears Division Expertise
Integrated chain + gearbox engineering optimises torque transmission for industries from food processing to automotive assembly—reducing total system complexity.
Triple Fatigue Life
Shot-peened link plates and case-hardened pins withstand 3x standard ISO 606 fatigue cycles—validated in cement, steel, and aggregate conveyors.
