Specialized Pocket-Tooth Sprockets

The interaction between the drive system and the chain is the most decisive wear-point in any high-torque production line. WELSCH manufactures sprockets engineered to maintain absolute profile integrity and provide mechanical safety, even in environments saturated with abrasive concrete dust or extreme thermal loads.

Specifically developed for the unique engagement geometry of our Rolling Block Link Chains, these bespoke sprockets are the kinetic heartbeat of the WELSCH drive system. Our pocket sprockets do not conform to generic industry standards; they are surgically defined by the specific chain, drive, and machine architecture of the client. With outer diameters up to 740 mm and pitch-circle diameters up to 690 mm, these double-track sprockets are manufactured either as monolithic units or as high-strength assemblies consisting of hub and twin pocket-toothed discs.

Parallel alignment mastery is achieved through high-strength tool steels and post-hardening EDM recutting, ensuring that the pockets in both discs are perfectly parallel. This eliminates chain pin misalignment, a critical failure point that is often ignored by standard manufacturers but is disastrous for system longevity.

WELSCH maintains a massive logistical hub of high-performance sprockets, stocking all standard sizes from 04B to 32B in simplex, duplex, and triplex configurations. We also manufacture specialized Push-Pin Sprockets for converting rotary motion into high-force linear motion, and Shear Pin Sprockets with calibrated failure points to protect mission-critical machinery during overload events.
