About this model

BL823 Leaf Chain (model BL823) is a standard item in the KEDI Leaf Chains range, with Series BL Series; Lacing 23; Material Heat-treated alloy/carbon steel; Application Forklift / mast lifting. It is produced to drawing and standard, inspected for dimensions and hardness before shipment, and can be supplied alone or as a matched set with mating transmission parts. Material, heat treatment, bore and surface finish can be adapted to the application.

Material & process

Material	Carbon steel or alloy steel plates, case-hardened pins, bushings and rollers
Heat treatment	Through-hardened plates; carburised pins and bushings for wear resistance
Surface	Pre-lubricated; black, shot-peened, zinc or nickel plated and stainless versions on request
Standards	ISO 606 / DIN 8187 (B series) and ANSI B29.1 (A series) dimensions
Custom options	Attachments (A/K/SA/SK), extended pins, hollow pins, special lengths and connecting links

Quality control

Pitch length measured under specified load
Tensile strength sampling per batch
Hardness of pins, bushings and plates checked after heat treatment
Visual check of riveting, rotation and lubrication before packing

How to select

Calculate design power: motor power multiplied by the service factor of the driven machine.
Choose pitch and number of strands from the power rating at the small sprocket speed.
Use at least 17 teeth on the small sprocket; keep a single-stage ratio below 7:1.
Set the centre distance at 30 to 50 pitches and plan lubrication for the running speed.
Order chain and sprockets together so pitch, roller width and tooth form match.
