RULAND MANUFACTURING

Ruland Manufacturing, founded in 1937 in Marlborough, Massachusetts, USA, is a manufacturer of precision shaft couplings and shaft collars. The company focuses on motion control components for applications requiring accurate torque transmission, misalignment accommodation, and secure shaft attachment. Ruland’s product families include beam couplings (both set screw and clamp-on types), rigid couplings, Oldham couplings, and shaft collars. These components are available in inch and metric dimensions, with bore diameters ranging from 1/8 inch to 3 inches and 3 mm to 80 mm, depending on the series. Materials include stainless steel (e.g., 303 and 304 grades) and aluminum (e.g., 2024-T4), selected for corrosion resistance, strength, or weight reduction. Ruland couplings are rated for angular misalignment up to 3 degrees (beam types) and axial motion up to 0.004 inches (Oldham hubs). Shaft collars are offered in one-piece clamp-on designs with round bores, in both inch and metric-with-inch-bore configurations. All components are machined to tolerances typical of motion control equipment, with surface finishes that minimize wear. 3G Electric stocks over 5,400 SKUs from Ruland, covering the full range of coupling types and collar sizes. Inventory includes both standard and less common bore combinations, such as different bore dimensions on each end of a coupling. 3G Electric provides global logistics support, enabling procurement teams to source these precision components for integration into automated machinery, packaging equipment, and other industrial systems where shaft alignment and torque transfer are critical. The catalog includes detailed specifications for each SKU, including bore diameter, material, misalignment ratings, and dimensional data, allowing engineers to select components based on application requirements without additional cross-referencing.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang RULAND MANUFACTURING dari 3G Electric.

What materials are Ruland Manufacturing shaft collars and couplings available in?

Ruland shaft collars are available in stainless steel (typically 303 or 304) for corrosion resistance, and couplings are offered in stainless steel or aluminum (2024-T4). Aluminum couplings are lighter and suitable for lower-torque applications, while stainless steel provides higher strength and durability in harsh environments. The specific material for each SKU is listed in the product specifications.

What is the angular misalignment capability of Ruland beam shaft couplings?

Ruland beam shaft couplings, such as the PSR20-8-5-A and PCR18-8-8-A, are rated for up to 3 degrees of angular misalignment. This allows them to accommodate minor shaft misalignments in motion control systems without excessive stress on bearings or shafts. The exact rating depends on the coupling size and design; always verify the specific SKU's specifications.

Are Ruland shaft collars available in metric bore sizes?

Yes, Ruland offers shaft collars in metric bore sizes, including models like the MCL-36E-ST, which has a metric bore with an inch collar width. The catalog includes both inch and metric options, as well as metric-with-inch-bore configurations, to suit different shaft standards. Check the product specifications for bore diameter and system type.

Can Ruland couplings accommodate different bore diameters on each end?

Yes, many Ruland couplings, such as the PSR20-8-5-A and PSMR22-8-7-A, are designed with different bore diameters on each end. This feature allows them to connect shafts of different sizes, which is common in machinery where a motor shaft and a driven shaft have different diameters. The product specifications indicate whether the bores are the same or different.

What is the difference between set screw and clamp-on Ruland couplings?

Set screw couplings, like the PSR20-8-5-A, use set screws to secure the coupling to the shaft, providing a simple, low-cost attachment. Clamp-on couplings, such as the PCR18-8-8-A, use a clamping mechanism that distributes force evenly around the shaft, reducing the risk of shaft damage and allowing for higher torque transmission. Clamp-on types are preferred for applications requiring frequent disassembly or higher precision.

Does 3G Electric supply RULAND MANUFACTURING products?
