R162342222 is a high-precision carbon steel ball slide block manufactured by Bosch Rexroth, with a specification of 45, narrow and extended standard height (SLS), featuring a low-noise ball chain and C2 average preload. R162342222 ball slide blocks are characterized by high rigidity, ultra-low stroke error, and long service life with no maintenance required. They are specifically designed for high-precision automation and mechanical transmission systems where lateral installation space is limited.
The Bosch Rexroth R162342222 slider has the following key features:
High load capacity: Utilizing a four-row ball recirculation design, it can simultaneously withstand vertical, horizontal, and tilting 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: H-class accuracy combined with a C1 low preload design ensures smooth movement while improving equipment operating accuracy and repeatability.
Low friction and long service life: The low coefficient of rolling friction reduces drive energy consumption and component wear, supports long-term lubrication, and extends service life.
Good high-speed performance: Suitable for high-speed linear motion environments, meeting the speed and stability requirements of automated equipment and CNC machine tools.
Strong installation compatibility: Compatible with various Rexroth standard guide rail specifications, facilitating installation and maintenance, and can be directly used in automated production lines and mechanical equipment upgrades.
Wide range of applications: It is widely used in CNC machine tools, automation equipment, electronic manufacturing, precision machining equipment, heavy-duty linear modules and industrial robots.
Due to its high rigidity, high precision, and high load-bearing capacity, R162342222 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
