The Bosch Rexroth C.ROL.R.BLOCK AL LWA-020-SNS-FN-E-0 (R190211900) is a high-quality cam roller runner block designed for linear motion systems. This component is part of the size E profiled rail systems and is constructed with an aluminum body for a lightweight yet durable structure. The runner block features a slimline width, standard height, and normal length, falling under the economic accuracy class E. It boasts a standard load-carrying capacity suitable for various applications. Equipped with a two-row angular-contact ball bearing, this runner block is sealed and lubricated for life, ensuring reliable performance and minimal maintenance requirements. The guide tracks are secured and made from corrosion-resistant precision steel shafts, enhancing the system's longevity. Notably, the runner block can be adjusted to zero clearance using eccentric spigots, allowing for precise movement control. The Bosch Rexroth C.ROL.R.BLOCK AL has interchangeable elements that withstand high loads in all four main directions, including moments about all axes. It includes wiper and lubrication units on both sides with large oil reservoirs, further contributing to its efficiency and extended service life. With its self-aligning capabilities, the runner block compensates for any misalignments in the system, ensuring smooth operation even under less-than-ideal conditions. The product operates effectively within a temperature range of -10°C to +100°C and can handle maximum permissible speeds (vmax) for average loads without preload clearance. This cam roller runner block is part of product group ID 20 and has been specifically developed by Rexroth for use in handling and automation technology applications due to its robust design and dynamic performance capabilities. With an overall weight of 0.3 kg (nominal size), it offers an optimal balance between strength and maneuverability within linear motion systems.

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.
