BLASI – Inner drive lever, A<1500
The BLASI – Inner drive lever A<1500 is a precision mechanical lever used inside BLASI revolving door drive assemblies for rotor actuation and linkage control on doors with lever length under 1500 mm. Machined from high‑strength steel and finished to resist wear and corrosion, the inner drive lever locates onto the drive shaft with keyed or bolted attachments to transmit torque to arms or linkages while maintaining alignment under dynamic loads. The compact profile and serviceable mounting points make the BLASI – Inner drive lever A<1500 suitable as an OEM replacement part for smooth, low‑play door operation.
Product Details
The BLASI – Inner drive lever A<1500 is an internal drive component engineered to transfer drive torque from the central motor shaft to the door’s internal linkage system on BLASI revolving doors where the lever arm length is less than 1500 mm. Designed for repeated cyclic loading, the lever is manufactured from hardened steel and treated for corrosion resistance; surfaces that interface with bearings or bushings are precision‑machined to preserve concentricity and minimise wear. Mounting is via standardised bores and keyways or high‑strength fasteners so the lever can be removed and replaced quickly during maintenance while maintaining accurate positioning relative to the drive geometry.
The lever’s geometry balances stiffness and clearance to avoid interference with adjacent components and to limit added inertia on the drive system, helping keep motor torque and control responses predictable. For field service, the BLASI – Inner drive lever A<1500 includes clear attachment points for safety springs or limit stops where used, and its robust construction reduces the risk of mechanical play that could otherwise cause vibration or uneven door motion.
