Product Details

Established in 1937, Ruland focuses on the design and manufacturing of high performing shaft collars and couplings. All products are carefully manufactured in Marlborough, Massachusetts factory under strict controls using proprietary processes.
PRODUCTS

SHAFT COLLARS

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. Ruland shaft collars are available in various materials and finishes, including:
• 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

D) DISC COUPLING

E) JAW COUPLING 

F) BEAM COUPLINGS 

G) SLIT COUPLINGS


UNIVERSAL JOINTS

Ruland universal joints are available in single and double configurations with friction or needle bearings. Single U-joints are comprised of two yokes and a trunnion assembly to allow for use in confined spaces and angular misalignment up to 45°. Double U-joints are comprised of two yokes, two trunnion assemblies, and a center yoke to allow for larger gaps between shafts, parallel misalignment, and angular misalignment up to 90°. U-joints are manufactured from high-grade alloy steel for high strength and stainless steel for corrosion resistance.
