説明
24B-G1 — ISO Heavy Series
The 24B-G1 Rubber Top Roller Chain is a heavy-duty conveyor chain for transporting surface-sensitive materials — varnished timber, float glass, laminated board and composite sheet — without marking, scratching or denting the product surface. A bonded NBR or NR rubber overlay on each link provides a compliant, non-abrasive contact surface. The alloy steel body underneath delivers the full 160 kN (36,363 lbf) tensile strength of a standard 24B-1 chain. No special sprockets needed — it runs on any ISO 606 / DIN 8187 24B-1 sprocket.
✓ 160 kN tensile strength
✓ Oil & heat resistant (NBR)
✓ ISO 9001 certified

Why specify rubber top chain?
Conventional steel roller chain leaves pressure marks, indentations and micro-scratches on finished surfaces. For production lines handling varnished timber, polished glass or laminated panel, even minor surface damage causes rejection and rework cost. The rubber top layer on the 24B-G1 distributes load across a compliant surface rather than a hard steel contact point — without sacrificing any structural capacity of the chain itself.
No surface marking
Flat NBR or NR overlay contacts the workpiece across the full plate width. No gouges, scratches or pressure marks on varnished, lacquered or polished material.
160 kN tensile strength
Thermally treated alloy steel chain body and pins handle continuous heavy-load conveyor duty. The soft contact surface does not reduce structural capacity.
Noise & vibration damping
The rubber overlay acts as a damping layer between chain and conveyed material, reducing operational noise versus bare steel chain under load.
Oil & heat resistance
NBR compound withstands contact with light oils and elevated temperatures common in timber mill, laminate press and plywood production environments.
Standard sprocket fit
Runs on any ISO 606 / DIN 8187 24B-1 sprocket at 38.1 mm pitch. No special sprockets or modified drives needed for most retrofits.
Custom configuration
Extended pins, K-attachments, special rubber widths and stainless steel chain bodies available to match machine-specific designs and OEM drawings.
Typical applications
Wood panel & plywood production
Transporting varnished, lacquered or sanded board between press, cooling and stacking stations.
Float glass handling
Carrying glass sheet between cutting, washing and stacking stations without surface contact damage.
Laminate & HPL conveyors
Protecting decorative surface layers of high-pressure laminate and composite sheet during processing.
Furniture component lines
Moving primed or painted parts through drying ovens where contact marks would require rework.
Aluminium profile cooling tables
Soft contact prevents scoring on anodised or powder-coated aluminium extrusion surfaces.
Matching sprockets
Any standard 24B-1 sprocket (ISO 606, 38.1 mm pitch, plain bore, pilot bore or taper-lock) is fully compatible with the 24B-G1 rubber top chain. For applications where further noise and impact reduction are required — particularly high-speed glass handling lines — rubber-cushioned sprockets (incorporating an elastomeric layer between hub and tooth ring) can be paired with this 鎖. Contact us with your shaft diameter, tooth count and centre distance and we will confirm the correct sprocket specification.
How to order
Provide the following details when you enquire:
- Chain model — 24B-G1 (or state the pitch if comparing sizes)
- Total length in metres, or number of links required
- Rubber compound — NR (natural, general purpose) or NBR (nitrile, oil-resistant)
- Chain body material — carbon alloy steel or stainless steel (SS304 / SS316)
- Any special attachments — extended pins, K-attachments, inner/outer plate tabs
- Surface treatment, if different from standard blackening
Sample orders: approx. 20 working days. Production orders: approx. 45 days from order confirmation. Mill test certificates available on request. OEM and own-brand labelling accepted.
