B Series Short Pitch Chain Simplex Transmission Roller Chain

B Series Short Pitch Chain Simplex Transmission Roller Chain is a single-strand industrial roller chain for power transmission and light-to-medium conveyor drives. Its roller, bush, pin and plate construction transfers rotary motion between sprockets with controlled pitch engagement. Standard 05B–16B sizes are available, with OEM configurations supported for dimensions, materials and attachments.

Factory Pre-Stretching: Pre-loaded to 30%–35% of ultimate tensile strength (UTS) to eliminate initial mechanical elongation and reduce early-stage system tensioning maintenance.
Shot-Peened Components: Link plates and rollers undergo high-intensity shot-peening to introduce compressive surface stress, increasing dynamic fatigue life by up to 25%.
Controlled Hardness Depth: Pins and bushes are case-hardened to HRC 58–62, maintaining high core toughness with superior wear resistance against continuous sliding friction.

Raw Material Inspection - Incoming steel is checked against the specified material grade and purchasing requirements before production.
Blanking & Forming - Inner and outer plates are formed to the required geometry, with dimensional checks performed on critical features.
Precision Machining - Pins, bushes and rollers are machined to controlled dimensions to maintain proper articulation and sprocket engagement.
Heat Treatment - Relevant components undergo controlled heat treatment to achieve the required hardness and wear characteristics.
Component Inspection - Pitch, roller diameter, inner width, pin diameter, plate dimensions and other critical dimensions are checked against the production specification.
Chain Assembly - Pins, bushes, rollers and plates are assembled using controlled processes to maintain consistent joint movement and alignment.
Lubrication & Surface Check - Assembled chains are checked for movement, surface condition, lubrication and visible manufacturing defects.
Tensile / Performance Testing - Testing can be arranged according to the agreed specification or inspection requirement.
Final Inspection - Finished chain length, configuration, appearance, packaging and identification are verified before shipment.
Export Packing Inspection - Polybags, cartons, pallets or wooden cases are checked to ensure the ordered quantity and packaging configuration are correct.
