Heavy-duty straight-plate roller chains are engineered roller chains designed for demanding power-transmission and material-handling equipment. The straight-plate construction shown in the supplied drawing provides a clear, regular chain profile for sprocket engagement, chain routing, and equipment integration.
The technical drawing shows three configurations and reference views:
Chain-plate plan view with height H
SIMPLEX single-strand assembly
DUPLEX double-strand assembly
The supplied table includes six chain families, each with a SIMPLEX row and a DUPLEX row:
Z2814 / Z2814-2
Z3315 / Z3315-2
Z3618 / Z3618-2
Z4020 / Z4020-2
Z4824 / Z4824-2
Z5628 / Z5628-2
All exact dimensions and values in this page are transcribed from the supplied technical image. Public references are used only to supplement general heavy-duty roller-chain and simplex/duplex selection information.
Key Features
Straight-Plate Chain Geometry
The drawing shows straight side plates, rollers, pins, and connecting components arranged around a regular chain centerline. The straight-plate layout is suitable for engineering review, sprocket matching, chain-length planning, and replacement assessment.
SIMPLEX and DUPLEX Configurations
The supplied drawing distinguishes between:
SIMPLEX — single-strand roller chain arrangement
DUPLEX — double-strand roller chain arrangement
The duplex configuration uses two parallel chain rows. Its transverse pitch Pt, pin length L, breaking load Q, and weight per meter q differ from the corresponding simplex row in the supplied table.
Heavy-Duty Dimension Range
The table covers pitches from 88.90 mm to 177.80 mm and lists roller outer diameters from 44.45 mm to 88.90 mm. The exact model should be selected from the complete equipment and drive requirements rather than from pitch alone.
Engineering Reference Dimensions
The drawing includes the following visible dimension references:
H — chain plate height in the plan view
d — pin or component diameter reference shown in the drawing
The -2 model rows correspond to the DUPLEX configuration shown in the supplied drawing. The table’s L, Q, and q values change for the double-strand row. Verify the complete chain arrangement, sprocket width, transverse pitch, and alignment before ordering.
Typical Applications
Heavy-duty straight-plate roller chains are generally considered for industrial power transmission and material-handling equipment such as:
Equipment where straight side plates support the required chain routing
The correct application depends on the complete drive calculation, chain speed, sprocket or wheel design, load profile, shock loading, environmental conditions, lubrication, and maintenance plan.
OEM / ODM and Replacement Support
Custom review can be based on:
Chain number
SIMPLEX or DUPLEX configuration
Pitch
Roller diameter
Inner-plate width
Pin diameter
Pin length
Transverse pitch

Sprocket or wheel drawing
Packaging and delivery requirements
For replacement matching, provide an existing chain sample, sprocket photograph, pitch measurement, pin and roller measurements, chain arrangement, and operating conditions.
Material grade, heat treatment, coating, corrosion resistance, wear life, service life, noise level, and working-load rating are not specified in the supplied image. Confirm these items separately before including them in a purchase specification.
