Toothed roller chains
Toothed roller chains (also known as sharp-top or saw-tooth chains) are purpose-built for gentle, slip-free transport in sawmills, particle board plants and the timber processing industry. Unlike standard drive roller chains, the toothed plates grip directly into the conveyed material — logs, boards, glulam, particle board, MDF panels or coated aluminium profiles — ensuring positional accuracy with minimal slip. SENN supplies toothed roller chains in common pitches 24B (38.1 mm), 32B (50.8 mm) and special pitches, as single or multi-strand designs with block link plates. Available tooth profiles include pointed teeth for log turners and root reducers, flat teeth for board separators, and hardened infeed teeth for profile chippers and cut-off saws. Plastic clips and rubber pads are available for surface-sensitive goods. All chains are dynamically pre-stretched and delivered with optimised hot-dip initial lubrication — reducing chain elongation in service by up to 30% compared to standard chains. Standard types ex stock, custom designs to drawing. Typical wood-industry applications and internal references are summarised on the wood industry conveyor chains hub.
