R162321320 Original Rexroth Linear Bearing Block Specifications

Specification Details Explanation Industry Standards
Nominal Size 25 mm Represents the size of the linear bearing block, critical for compatibility with linear rails. DIN ISO 14728-1
Accuracy Class H (High) Indicates the high precision of the linear motion system, ensuring smooth and accurate travel. ISO 14728
Preload Class C1 (Low Preload) Low preload ensures minimal friction, optimizing speed and reducing wear over time. DIN 6485
Dynamic Load Capacity 37,300 N Indicates the maximum load the bearing block can handle during dynamic motion. ISO 14728-1
Static Load Capacity 52,500 N The maximum load the bearing block can bear while at rest without any movement. DIN ISO 14728
Friction Coefficient 0.002 – 0.003 Represents the resistance to motion between the linear bearing block and guide rail, contributing to energy efficiency. ANSI/B93.55M
Lubrication Type Initial lubrication with Dynalub 510 Ensures the smooth operation of the bearing block upon installation, with minimal maintenance required. ISO 14728
