Description
The KH2540 NTN Ball Sleeve (Linear Ball Bushing) is engineered for precision linear motion in industrial and automation systems. Designed according to ISO dimensional standards, this ball sleeve delivers smooth and efficient linear movement with minimal friction.
Constructed with a hardened steel outer sleeve and a durable PA (polyamide) cage, the KH2540 ensures strength, stability, and long service life. Its six rows of recirculating balls provide even load distribution, enhancing performance and reliability under dynamic operating conditions.
Although supplied without initial greasing, the bearing is fully relubricable, allowing for easy maintenance and extended operational life. This makes it suitable for use in linear guides, automation equipment, packaging machines, and other applications requiring accurate and consistent linear motion.
