Metric pitch timing belts

Metric pitch omega-tooth profile timing belts: 2M 3M 5M 8M 14M S2M S3M S5M S8M S14M
Metric pitch omega-tooth profile double timing belts: D5M D8M DS8M D14M DS14M
Their teeth have a rounded, so-called omega shape, with pitch measured in millimetres (from tooth centre to tooth centre). They are generally made of neoprene with tension cords. Based on tooth shape, we distinguish HTD and STD versions. HTD belts can usually be used in both HTD and RPP pulleys.

Metric pitch polyurethane timing belts: T2.5 T5 T10 T20 AT3 AT5 AT10 AT20
Metric pitch polyurethane double timing belts: DT2.5 DT5 DT10
Their teeth are trapezoidal, with pitch measured in millimetres (from tooth centre to tooth centre). They are typically made of polyurethane, with tension members made from steel, aramid, or Kevlar cords.

Metric pitch polyurethane timing belts with carbon reinforcement: 8MDC 14MDC
Among the strongest polyurethane timing belts. Their teeth are trapezoidal, with pitch measured in millimetres (from tooth centre to tooth centre). The belt body is polyurethane with carbon fibre tensile cords.
