The Bosch Rexroth R162341222 is a high-precision, heavy-duty ball slide block suitable for 45-inch linear guideways. It features a four-row circulating ball structure and low preload design, and is characterized by high rigidity, high load capacity, low friction, and smooth and quiet operation. It is widely used in CNC machine tools, automated equipment, and precision linear motion systems.
The Bosch Rexroth R162341222 has the following key features:
High load capacity: Utilizing a four-row ball recirculation design, it can simultaneously withstand vertical, horizontal, and overturning loads, making it suitable for heavy-duty, high-rigidity operating conditions.
Smooth operation and low noise: Built-in ball chain technology reduces collisions and friction between the balls, resulting in smoother and quieter operation at high speeds.
High-precision positioning: P-level precision combined with a C1 low preload design ensures smooth movement while improving the equipment's operational accuracy and repeatability.
Due to its high rigidity, high precision, and high load-bearing capacity, R162341222 ball bearing slides are mainly used in the following industrial automation and machinery manufacturing industries:
1. CNC machine tools and metal processing industry
2. Laser technology and advanced manufacturing
3. Semiconductor, electronics, and microelectronics industry
4. Industrial robots and automated production lines
5. Precision measuring and testing instruments
6. Woodworking and plastics processing machinery
