The Bosch Rexroth R162421820 high-precision ball slide is a 25-size narrow-profile extended SLH ball slide with a carbon steel construction, suitable for applications with limited lateral space and high rigidity requirements.
The Rexroth SLH ball slide is an extended, high-center-of-gravity, narrow linear guide slide. It offers extremely high load capacity and rigidity, and is widely used in automated and CNC machinery with stringent precision and space requirements.
SLH R162421820 Ball Slide Core Features and Benefits
High Load Capacity and High Rigidity: Offers equally high rated loads in all four main load directions, with extremely high rigidity and torque load capacity.
Excellent Dynamic Performance: A special ball circuit design minimizes friction and vibration, ensuring smooth and quiet operation.
Long Life and Low Maintenance: Factory pre-lubrication and optimized raceway and seal design allow for years of maintenance-free operation.
High interchangeability: Sliders and guides of the same precision grade can be freely combined, allowing for interchangeable parts.
Flexible sealing options: Supports a variety of seals including standard seals (SS), low-friction seals (LS), double-lip seals (DS), and front seals.
