Rigid couplings and shaft collars from Ruland ensure precision, hygiene and reliability
Ruland’ s shaft collars and rigid couplings are engineered to meet the demanding needs of food processing, packaging, and handling systems, offering solutions that enhance efficiency and reduce downtime.
Rigid couplings are available in a wide variety of sizes and styles for food packaging applications such as case erectors, cartoners, and form, fill, seal equipment. The couplings are ideal for shaft-to-shaft connections and precise servo driven applications as they do not introduce misalignment, vibration, or bearing noise into the system. They have precision honed bores, anti-vibration hardware, and opposing hardware on two-piece styles to ensure superior fit, alignment and holding power. Ruland offers 303 stainless steel couplings with hardware of like material as standard stock items. Proprietary Nypatch antivibration hardware is used to prevent galling, provide event seating of the screw, and allow for repeated screw installations.
Clamp style shaft collars are commonly used for guiding, spacing, stopping, mounting and component alignment. The shaft collars have a tightly controlled face to bore perpendicularity( TIR of ≤ 0.05 mm) which is critical when used as a load bearing face or for aligning components such as bearings or gears. They are machined to a fine burr free finish that reduces the likelihood of metallic system contamination. Shaft collars made from 303 and 316 stainless steel utilize hardware of like material for consistent corrosion resistance and to meet regulatory standards. Plastic shaft collars can be used as a costeffective alternative to stainless steel at the expense of performance. They are supplied with stainless steel hardware for corrosion resistance. Ruland also offers anodized aluminium shaft collars with stainless steel hardware for areas of the system where stainless steel or plastic is not required.
