Bosch Rexroth modified its CKK and CKR Compact Modules for damp environment applications in the food and packaging industries. Key modifications for operating in damp environments include chrome plating of internal components. To reduce the likelihood of corrosion, all external hardware is stainless steel. In addition, holes can be drilled into the anodized aluminum housing to allow fluids to drain safely. The CKK uses a ball screw for system rigidity for heavy payloads or complex end-of-axis tooling. The belt-driven CKR uses a steel-reinforced polyurethane belt with aluminum pulleys. Both models have dual-ball rail system guides. With a load capacity up to 56,530N, the CKR operates at speeds up to 5 m/s. Full-contact seals retain the food-grade grease lubricant for both the ball rail and ball screw. Target applications include cartoners, laners, product sorting or diverting, filling and dispensing machines. For more information, go to http://rbi.ims.ca/4931-510.
