Sertifikalı Standart

B Series Short Pitch Precision Roller Chains are the global standard for European-dimensioned power transmission drives. Available in Simplex (–1), Duplex (–2), and Triplex (–3) configurations across 16 pitch sizes from 6 mm (04B) to 114.3 mm (72B), these chains cover applications from lightweight agricultural conveyors up to heavy industrial crawlers demanding over 3,000 kN tensile capacity.

All chains conform to ISO 606:2015 / DIN 8187 and are dimensionally interchangeable with any manufacturer producing to the same standard. Manufacturing controls include precision-ground pins and bushings, induction-hardened wearing surfaces, shot-peened link plates for fatigue resistance, and pre-loading during assembly to minimise initial elongation in service.

Chain Selection Guide

Calculate Design Load

Find peak chain pull (kN). Multiply by service factor: 1.0 smooth / 1.3–1.5 moderate shock / 1.7–2.0 heavy shock. Select chain where Q min exceeds result.

Choose Strand Count

Duplex ≈ 1.8× simplex load; Triplex ≈ 2.6×. A smaller pitch duplex often saves space and sprocket weight versus a larger simplex at the same load.

Match Sprocket & Centre Distance

Standard sprockets for all B-Series pitches are stocked. Confirm tooth count and centre distance before finalising pitch. Custom tooth counts available.

Specify Connecting Links

Standard slip-fit links supplied. Request press-fit or cotter-pin links for high-speed or vertical drives. Note straight-plate (06B) requires matched link type.

Manufacturing & Quality Standards

⚙

Precision Ground Components

Pins and bushings ground to ISO 606 tolerance classes for consistent roller articulation and minimal noise.

🔥

Induction Hardened Wearing Surfaces

Pin and bushing contact surfaces hardened to 58–62 HRC for extended wear life under high-cycle operation.

🛡

Shot-Peened Link Plates

Compressive residual stress from shot-peening increases fatigue life significantly, particularly on reversing and shock-load drives.

📐

Pre-Loaded Assembly

Each chain is pre-stretched under controlled load to reduce initial service elongation and ease tensioner setup.

✅

Batch Tensile Testing

Every production batch proof-tested against ISO 606 minimum breaking load. Test certificates available on request.

🔗

DIN/ISO 606 Interchangeable

Drop-in replacement for any chain built to DIN 8187. No sprocket changes required when switching suppliers.

Typical Applications

🌾 Agricultural Machinery

Combine harvesters, grain conveyors, bale handlers, planter drives, row-crop equipment with ISO sprockets.

📦 Material Handling

Pallet conveyors, live-roller tables, bucket elevators, and overhead trolley systems for multi-shift schedules.

📋 Packaging Machinery

Indexing drives, pushers, synchronised multi-axis conveyors where pitch precision and low elongation are critical.

⚙ General Power Transmission

Machine tools, pumps, fans, compressors, and gearbox-to-shaft drives across all industrial sectors.

🏗 Heavy Construction Equipment

32B–72B used in crawler undercarriage assemblies, crane slewing drives, and tracked vehicle final drives.

🏭 Food & Beverage Processing

Stainless-steel and nickel-plated variants available on request for wash-down and corrosion-resistance requirements.
