Ruland Manufacturing SP-7-ST 2-Piece Clamp Shaft Collar 7/16 in 316 SS

Precision Shaft Collar for 7/16 Inch Round Bore

The Ruland SP-7-ST is a two-piece clamp collar machined from 316 stainless steel for a 7/16 inch round bore. Its 15/16 inch outside diameter and 11/32 inch width suit precision shaft positioning in compact assemblies. The 1.08 inch clearance diameter provides room for adjacent hardware. This collar serves maintenance crews and OEM builders who need corrosion-resistant retention without shaft marring.

Consistent Clamping Force Under Continuous Operation

The two-piece design distributes clamping load evenly around the shaft, resisting axial shift during sustained vibration or torque cycles. Stainless steel screws maintain preload without galling, so the collar holds position through extended duty periods. The 316 grade resists chemical attack that can weaken lesser alloys over time. No keyway or threaded bore means the grip relies purely on uniform radial pressure.

Split Construction Enables In-Place Installation

The hinged two-piece body opens fully, allowing fitment or removal without sliding components off the shaft end. This saves disassembly time on gearboxes, conveyors or pump drives where bearings or couplings block axial access. The 316 stainless material withstands wash-down environments and outdoor exposure. California Proposition 65 labelling notes a reproductive-harm chemical; handlers should follow site safety protocols.
