Ruland Shaft Collars And Couplings

Product Description

Ruland is a domestic manufacturer of shaft collars in multiple styles to fit shafts ranging from 1/8 to 6" and 3mm to 150mm. Shaft collars play a critical role in most industrial equipment, where they are used for guiding, spacing, locating, component alignment, and axial stopping. Ruland shaft collars are trusted in thousands of applications worldwide to operate without failure. We take extra care in the design and manufacturing of our shaft collars to maximize their performance in any application, including:
Ruland shaft collars are available in various materials and finishes

303 & 316 stainless steel with hardware of like material for consistent corrosion resistance.

1215 lead-free steel with proprietary black oxide or yellow zinc plated finish for compliance in all applications.

RIGID COUPLINGS

Rigid shaft couplings are available with or without keyways in one- and two-piece and set screw designs. Ruland manufactures them from select North American bar stock in 2024 aluminium for lightweight and low inertia, 1215 lead-free steel for general purpose use, and 303 stainless-steel for high corrosion resistance. Straight and step bore type rigid couplings are standard products for shafts ranging from 1/8" to 2" and 3mm to 50mm. Inch to metric conversion couplings are available by special order. Each rigid coupling is stamped with the Ruland name and the bore sizes for ease of identification.

RULAND SERVO COUPLINGS

Servo couplings from Ruland are available in a wide variety of styles, sizes, and materials to match differing application requirements. Choosing the correct servo coupling can be a difficult process that involves many performance factors including: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these factors is critical to system performance. Ruland offers servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types allowing the user to select the coupling that best fits their application.

A) OLDHAM COUPLING - Ruland oldham couplings are a three-piece assembly with a balanced design comprised of two hubs and a center disk. This allows for a highly customizable coupling that allows the user to combine clamp and set screw hubs with inch, metric, keyed, and keyless bores in sizes ranging from 1/8" to 1-1/8" and 3mm to 30mm. The center disk is available in three materials to allow designers to fit the coupling to their application requirements. While oldham couplings can accommodate small amounts of angular and axial misalignment, they are especially useful in parallel misalignment accommodating up to 10% of their OD in misalignment. 

B) BELLOWS COUPLING

C) CONTROLFLEX COUPLINGS
