The Timken Company - SXCS-6 Type Hubs - Rough Stock Bore

Batch CAD Cart (0) ▾

The SXCS Type is the standard 6 bolt coupling with two hubs, two mounting rings, two disc packs and a split spacer designed for ease of installation and maintenance. Custom spacer lengths can be specified for special applications. The coupling has two flex planes (one at each disc pack) allowing it to accommodate parallel misalignment by the angular misalignment in each disc pack. This configuration will also accommodate axial misalignment within the specified limits.

¹ Operating speed must be equal or less than permissible speed which is limited by the weight and critical speed of the spacer. ² Couplings as manufactured can accommodate maximum speeds as listed. Higher speeds up to the value shown as 'Bal' require special balancing. ³ Weight is given for a complete coupling with minimum BSE and maximum bores. ⁴ Axial misalignment is given for two disc packs ⁵ Angular misalignment is given for one disc pack. ⁶ OAL is measured from the end of the hubs and does not include the bolt heads. ⁷ The maximum bores shown are for cylindrical or taper shafts with keys. ⁸ BSE is the distance between shaft ends and is a variable parameter
