R165352310 Original Rexroth Linear Bearing Block Parameters

Parameter Value Explanation
Nominal Size 55 mm (2.165 in) Defines the size category, ensuring compatibility with corresponding guide rails.
Format FLS – Flange, Long, Standard Height Indicates flanged width, extended length, and standard height for robust applications.
Material Carbon Steel High-strength material ensures durability and resistance to wear.
Preload Class C2 – Medium Preload Provides balanced rigidity and smooth motion for heavy loads.
Accuracy Class H – Highly Accurate Ensures precise positioning, critical for high-precision machinery.
Seal SS – Standard Seal Protects against contaminants, extending service life.
Ball Chain Without Ball Chain (Standard) Simplifies design, reducing friction and maintenance.
Width of Runner Block 140 mm (5.512 in) Wide base enhances stability and load distribution.
Length of Runner Block 199 mm (7.835 in) Extended length supports higher load capacities.
Height of Runner Block 57 mm (2.244 in) Standard height ensures compatibility with various systems.
Height with Guide Rail 70 mm (2.756 in) Total height including rail, critical for system design.
Dynamic Load Capacity C100 139,000 N (31,248 lbf) Maximum load for 100,000 m travel, per DIN ISO 14728-1.
Dynamic Load Capacity C50 175,000 N (39,342 lbf) Maximum load for 50,000 m travel, offering higher capacity for shorter distances.
Static Load Capacity C0 245,000 N (55,078 lbf) Maximum static load the block can withstand without deformation.
Maximum Acceleration amax 250 m/s² (820 ft/s²) Supports high-speed operations; reduces to 50 m/s² under specific load conditions.
Maximum Linear Speed vmax 5 m/s (16.4 ft/s) Ensures efficient motion in dynamic applications.
Permissible Ambient Temperature -10 °C to +80 °C (14 °F to 176 °F); 100 °C (212 °F) for short periods Wide temperature range supports diverse industrial environments.
Friction Coefficient μ 0.002 to 0.003 Low friction enhances efficiency and reduces wear.
Weight 6.8 kg (14.99 lb) Balanced weight ensures stability without excessive bulk.
