Chain is treated for long-life performance

A Rexnord UK product story
Edited by the Engineeringtalk editorial team Dec 6, 2005

Available as both roller and leaf chains, RexPro is fabricated from selected steels with all components heat treated in-house using the latest advanced technology.

RexPro, the new chain from Rexnord, has been developed to provide superior performance and durability combined with excellent green credentials.

It also offers significant financial savings compared with similar duty stainless steel or coated chains from alternative manufacturers.

The company is launching and supporting RexPro via a new and expanding nationwide network of distributors.

Available as both roller and leaf chains, RexPro is fabricated from selected steels with all components heat treated in-house using the latest advanced technology.

Manufacturing processes include shot peening for enhanced material strength, high-preloading to minimise elongation and ball drifting together with seamless rollers to ensure smooth articulation.

These features are enhanced by a special lubricant coating that is applied after assembly.

Tests have proven RexPro chain to have up to 12% improved wear resistance plus 150% higher protection against cold welding (DIN51834) compared with its predecessor.

In addition, it performs 8-10x better in the DIN salt spray test (DIN50021 SS/ISO9227 SS), providing up 100% better link articulation even with long term exposure to aggressive and corrosive environments during use or equipment storage.

Environmentally, the new chain employs no heavy metals, no PTFE and no silicon, thereby exceeding all current environmental standards (NSF-H2 Certification for food industry and RoHS/2005 for electric/electronic equipment) thereby satisfying the environmental expectations of market leading manufacturers.

Maintenance of these high standards is assured thanks to an environment management system (ISO14001:2005) and quality management system to ISO9001.

Rexnord's RexPro roller chains are available in sizes (BS and ANSI) from 04 to 72 B-3 and leaf chains in sizes from AL422 to F76-99.
