Ruland Manufacturing 2-Piece Clamp Shaft Collar 50 mm 303 SS

Precision shaft collar for metric shafts

The Ruland Manufacturing 2-Piece Clamp Shaft Collar fits a 50 mm round bore and is machined from 303 stainless steel. Its two-piece construction allows installation or removal without sliding the collar along the shaft, which is useful when adjacent components cannot be disassembled. The collar suits power-transmission and machine-shop applications that require a secure axial stop or positioning reference on metric shafts.

Two-piece clamp with stainless fasteners

A 19 mm wide body provides a 78 mm outside diameter and an 84.7 mm clearance diameter for tool access. Both the collar and its socket-head cap screws are 303 stainless steel, giving corrosion resistance in wash-down or humid environments. The split design with recessed screw heads reduces snag risk and allows the collar to be tightened in place around existing shafts, bearings or gears.

Stable holding force with minimal maintenance

The clamp action distributes holding force evenly around the 50 mm bore, preventing shaft marring while resisting axial loads and vibration. Stainless steel construction eliminates the need for protective coatings that can wear off, so the collar maintains its grip and appearance through repeated adjustment cycles. No lubrication is required, and the material withstands typical industrial temperatures without degradation.
