Roller Chain with Vulcanised Elastomer Profiles

Raydafon vulcanised elastomer roller chains combine precision-engineered steel roller chain with vulcanised NBR rubber profiles (80 Shore A hardness) that prevent scratching, marring and surface damage during conveyor transport. Available in sizes 08B to 24B with G1 (single-side) and G2 (double-side) profiles, pitch 12.7mm to 38.1mm. Operating temperature range: -30°C to +100°C. The rubber profile delivers high cohesive friction to grip and advance fragile goods — coated sheet metal, planed timber, glass panels, pipes, cartons and food packaging — without marking or deformation. Standard carbon steel, alloy steel (42CrMo/20CrMo) or stainless steel (SS304/SS316) base chain. Custom profile shapes, natural rubber or polyurethane alternatives, and OEM branding available. Send chain size, profile type, quantity and destination port for a confirmed quotation within 24 working hours.

Typical Applications

Vulcanised elastomer roller chains are specified wherever conveyed products must remain unmarked, unscratched and undamaged. These chains are widely used for transporting goods that should not be scratched, such as coated or thin sheet metal, planed timber planks or pipes.

Glass & Ceramics Gentle transport of glass panels, ceramic tiles and fragile components without surface marks.
Coated Sheet Metal Pre-painted or coated metal sheets are moved without scratching the finish.
Planed Timber Finished wood planks and panels retain their surface quality during conveyor transfer.
Pipes & Profiles Plastic pipes, aluminium profiles and extrusions are gripped and advanced without deformation.
Food Packaging Cartons, trays and packaged food items are moved quietly and hygienically.
Pharmaceutical Vials, blister packs and medical devices are conveyed without vibration or surface damage.

Rubber Material Comparison

Choose the right elastomer compound for your specific conveyor environment. NBR is standard; natural rubber and polyurethane are available on request.

Best For	General industrial, oily environments	High-grip, low-temperature	Heavy abrasion, cutting edges

How to Select the Right Elastomer Roller Chain

Identify conveyed material Glass, sheet metal, timber, pipe, food packaging — determines grip and hardness requirements.
Select rubber hardness Softer (65 Shore A) for delicate surfaces; harder (80–85 Shore A) for heavier loads.
Determine chain size 08B to 24B depending on load, speed and sprocket dimensions.
Choose profile type G1 (one side) or G2 (both sides) — or provide a drawing for custom geometry.
Confirm temperature Standard NBR covers -30°C to +100°C; alternatives available outside this range.

Why Choose Raydafon Vulcanised Elastomer Roller Chains?

Vulcanised Bond Rubber is vulcanised directly onto the chain link, creating a permanent bond that resists peeling and detachment under load. All chain plates are tapered and shot-blasted for high contact ratio.

Precision Base Chain Heat-treated alloy steel pins and bushings ensure high tensile strength and long service life in continuous operation. Seamless cold-extruded rollers with extremely regular wall thickness.

Frequently Asked Questions

What is a roller chain with vulcanised elastomer profiles used for?

Vulcanised elastomer roller chains are used in conveyor systems where fragile or surface-sensitive goods must be transported without scratching, marring or deformation. The vulcanised rubber profiles on the chain surface grip and advance items such as coated sheet metal, planed timber planks, glass panels, pipes, cartons and food packaging through the production or logistics line.

What rubber material is used and what is its hardness?

The standard elastomer profile is made from nitrile butadiene rubber (NBR) with a hardness of 80 Shore A. NBR combines cohesive friction, abrasion resistance and durability. The available hardness range is 65–85 Shore A. Natural rubber or polyurethane profiles are available on request for applications requiring different friction or chemical resistance characteristics.

What chain sizes and pitch options are available?

Sizes range from 08B (12.7 mm pitch) to 24B (38.1 mm pitch), covering both ISO/DIN and ANSI standards. G1 profile (rubber on one side) and G2 profile (rubber on both sides) are standard. Custom profile shapes can be manufactured from drawings for specific conveyor applications.

What is the operating temperature range?

The standard NBR elastomer profile operates from -30°C to +100°C. At the extreme ends of this range, hardness and friction values may change. For applications outside this range, alternative rubber compounds can be evaluated.

Can you customize the rubber profile shape or chain material?

Yes. We support full OEM/ODM customization including custom rubber profile geometry, rubber compound selection (NBR, NR, PU), base chain material (carbon steel, 42CrMo alloy steel, SS304/SS316 stainless steel), and branded packaging. Send your drawing or sample for engineering review.
