Ruland Manufacturing SP-28-A 2-Piece Shaft Collar 1-3/4 in Aluminum

Ruland SP-28-A 2-Piece Shaft Collar

This Ruland Manufacturing SP-28-A is a 2-piece clamp-style shaft collar designed for 1-3/4 inch round bores. It suits maintenance and assembly tasks where a collar must be installed or repositioned without sliding components off the shaft end. The aluminum construction keeps weight low while providing adequate holding power for light- to medium-duty power transmission setups.

Thermals Noise and Power Draw

As a passive mechanical fastener, this collar generates no heat, produces no audible noise and draws no electrical power during operation. Performance depends on correct screw torque and shaft surface finish rather than thermal or electrical limits. The alloy steel screws maintain clamping force without the thermal cycling concerns that affect active components.

Bundled Accessories and Software

The collar ships as a single hardware unit with no bundled software, lubricants or additional hardware. California Proposition 65 notices apply because the material contains a listed chemical, so users handling the part should follow standard workshop hygiene. No driver installation, firmware updates or calibration procedures are required for this mechanical component.
