10PCS OWC511 OWC511GXLZ OneWay Needle Roller Bearings 5x11x5.4 Product overview Compact oneway needle roller clutches designed for precise rotation control in small electromechanical equipment. Supplied as a set of 10 pieces, models OWC511 and OWC511GXLZ match the 5x11x5.4 size specification for direct replacement in compatible assemblies. Key benefits Oneway engagement for controlled freewheeling and indexed motion, preventing reverse drive when engaged. Compact 5x11x5.4 profile fits tight spaces and small shafts where footprint is critical. Set of 10 allows multiple replacements or spare stock to reduce maintenance intervals. Precision rolling elements deliver consistent engagement and repeatable operation in cycle applications. Straightforward swapin replacement for devices designed for the OWC511 size, minimizing downtime. Features and attributes Function: Oneway needle roller bearing clutch for unidirectional drive and freewheeling. Models: OWC511 and OWC511GXLZ included, matching the specified dimensions and function. Size: 5x11x5.4 (inner diameter x outer diameter x width). Quantity: 10 pieces per pack. Performance: Engineered for precise engagement and reliable operation in compact mechanisms. Compatibility: Intended for chip mounter printers and other small automation equipment that accept 5x11x5.4 oneway roller clutches. Typical applications Replacement clutch elements in SMT chip mounter heads and pickandplace modules to restore correct feed and release behavior. Drive and indexing components in small conveyor sections or rotary tables that require oneway engagement. Hobby and industrial robotics where compact oneway clutches are needed for wheel drives, actuators, or tensioning mechanisms. Installation and usage notes Designed as a direct replacement for assemblies that accept the OWC511 size and specifications. Verify shaft diameters and housing clearances before installation. Install with appropriate press or fit tools to avoid damage to rolling elements. Follow machine manufacturer guidance for lubrication and torque settings if applicable. Keep a set of spares on hand for routine maintenance to minimize production interruptions. What this product solves Restores unidirectional drive control in compact mechanical systems. Provides a uniform, replaceable component that simplifies maintenance for machines using 5x11x5.4 oneway roller clutches. Enables consistent performance in cycle environments where precise engagement is required.
