The JSLT-CG-CT2-12B2 is a mid-duty double-row CT-type steel-backed guideway matched to 3-strand ISO 12B-2 chain (pitch 19.05 mm — the global workhorse pitch for food, beverage, and assembly conveyors). The UHMWPE PE1000 wear-strip (30 × 20 mm overall) carries 3 chain pockets (2.9 × 8.0 mm), locked into an SS304 tube C2911 via a 13.0 mm slot so the cap overhangs and seals the SS tube from above.
Cross-section — all dimensions in mm. Drawn to 1:1 scale (within page width).
This is the twin-strand rail you'll see in heavy-duty European bottling and assembly plants where chain replacement intervals matter more than initial cost. The SS304 tube takes the chain pull (over 30 kN per strand allowable); UHMWPE only sees abrasion and friction. When the polymer wears out at 18–36 months, slide a fresh strip in from the tube end face — no machine downtime longer than a coffee break, no machining on site. The 12.0 mm shoulder height gives chain plates a dedicated wear surface so they never contact the SS edge.
ISO 12B-2 3-strand roller chain (pitch 19.05 mm). Compatible with all chains conforming to ISO 606 / DIN 8187 / BS 228 envelopes, including ANSI #60, BS 12B-2, JIS RC76 equivalents. Roller, plate, and pin geometry of these standards are interchangeable; the JSLT-CG-CT2-12B2 guideway profile accepts any of them across all 3 parallel pockets without modification.
CNC-milled groove with R-radius transitions, surface roughness Ra ≤ 1.6 µm typical. Polished groove option available for sticky-product lines.
