LBCR30D Ewellix Closed Linear Ball Bearing 30x47x68mm
The LBCR30D Ewellix Closed Linear Ball Bearing is a medium-sized precision linear bearing engineered for reliable performance in demanding industrial applications. Designed and manufactured by Ewellix, this bearing combines robust construction with exceptional load-carrying capabilities in a 30x47x68mm form factor, making it ideal for applications requiring smooth, precise linear motion with moderate to heavy loads.
Product Overview:
The LBCR30D features a cage and raceway segment design that effectively guides the balls while delivering outstanding load-carrying capacity. Built with an exceptionally long track length and machined raceway osculation, this closed linear bearing provides enhanced raceway segments positioned for maximum load carrying capacity, making it suitable for installation in both closed and adjustable housings.
Key Features:
- Medium-sized compact dimensions (30mm inside diameter, 47mm outside diameter, 68mm width) for versatile installation options
- Exceptional load-carrying capacity thanks to long track length and precision raceway design
- Closed design for protected operation in demanding industrial environments
- Steel and plastic construction for durability and lightweight performance
- Open bearing design without seals for minimal maintenance requirements
- Enhanced raceway segments positioned for maximum load carrying capacity
- No misalignment compensation - requires careful alignment during installation
- Wide operating temperature range: -30°C to +80°C

Applications:
The LBCR30D is well-suited for a wide range of industrial machinery and equipment requiring smooth linear motion with moderate to heavy load capacity, including:
- Industrial automation and conveyor systems
- Machinery requiring smooth, reliable linear motion with significant load support
- Precision positioning and assembly equipment
- Manufacturing and production line equipment
- Heavy-duty machinery operating across wide temperature ranges
- Applications where space efficiency and load-carrying capability are both critical
Installation Notes:
The LBCR30D must be positioned in the axial direction during installation, typically via the grease fitting or fixation pin. When mounted in closed housings, the bearing tolerance and operating clearance are determined by the housing bore tolerance, ensuring precise performance and reliable operation. When mounted in slotted or adjustable housings, the linear bearing can be altered to provide either operating clearance or pre-load depending on specific application requirements.
