The Bosch Rexroth LR-WAGEN U-FORM AL LWA-020-SNS-FN-E-0 (R190511900) is a high-performance cam roller runner block designed for use in handling and automation technology applications. This U-type runner block boasts a slimline width and standard length and height, making it a compact yet robust component for linear motion systems. Constructed from aluminum, the runner block offers an economic accuracy class E, ensuring cost-efficient operation without compromising on quality.
The LR-WAGEN U-FORM AL LWA-020-SNS-FN-E-0 is designed to work with size E profiled rail systems and is capable of enduring standard load capacities. It features a dynamic load capacity in the z-direction and y-direction, as well as static load capacities in both directions, ensuring reliable performance under various loading conditions. The unit's maximum operating temperature range extends from -20°C to 80°C, accommodating a variety of environmental conditions.
This model comes without initial lubrication or preservation, allowing for customization based on the specific lubrication needs of the application. It also excludes attachment elements on both left and right front reference edges for streamlined integration into existing systems. A lube nipple is included for maintenance ease.
The Bosch Rexroth LR-WAGEN U-FORM AL LWA-020-SNS-FN-E-0 has been engineered to provide smooth motion with its cam roller guides while maintaining durability and reliability over time. Its self-aligning capabilities allow it to compensate for any misalignments in the system, ensuring consistent operation and extending the lifespan of both the runner block and rail system. With its economic precision and robust construction, this runner block is an essential component for various linear motion applications within automation technology.

Rigidity
An increased rigidity can be achieved with higher pre-tensioning force by using eccentric setting.
Acceleration
High accelerations are permitted if slippage is avoided. For this, the pre-tensioning force FV by increasing the eccentric setting; see diagram.
Attention: The maximum permissible load is reduced by the increase of the pre-tensioning force.
