Product Introduction
The ZARF2575 TN is a robust, high-performance combined bearing crafted for precise axial and radial shaft location. Measuring 25 x 75 x 50 mm, this model features a standard flush shaft washer, making it highly versatile for various industrial machinery designs. The "TN" designation indicates a reinforced polyamide (nylon) cage that guides the rolling elements flawlessly, preventing metal-to-metal contact and drastically reducing operational noise. Produced in our state-of-the-art precision bearing facility, the ZARF2575 TN is engineered to deliver unyielding stiffness and micron-level accuracy, empowering our international B2B clients to build faster, more accurate manufacturing equipment.
Applications
Precision ball screw supports in CNC lathes.
Heavy-duty linear motion systems.
Rotary printing presses and high-speed packaging machinery.
FAQ
Q: What is the difference between TN and TV cages?
A: Both TN and TV denote polyamide (nylon) cages. Different manufacturers use these suffixes interchangeably, but both offer excellent low-friction and high-speed capabilities.
Q: Is the ZARF2575 TN preloaded?
A: Yes, these combined bearings are manufactured with a precise internal preload to ensure immediate rigidity upon installation.
