Product Introduction

The ZARF2068 L-TV-A is an advanced super-precision bearing designed to support multi-directional loads in high-end automation and machining centers. With dimensions of 20 x 68 x 60 mm, this bearing effectively merges radial needle rollers with bidirectional axial cylindrical rollers. The "A" suffix denotes an optimized internal geometry designed to maximize load capacity and extend fatigue life under heavy, continuous operation. Equipped with a stepped, extended inner washer (L) and a low-friction polymer cage (TV), the ZARF2068 L-TV-A is precisely calibrated to eliminate backlash and maintain absolute positional accuracy for critical ball screw assemblies across global B2B industrial sectors.

Applications

Multi-axis CNC milling and turning centers.
High-precision industrial robotic arm joints.
Heavy-duty ball screw and lead screw drives.

FAQ

Q: Does this bearing require a specific type of lubrication?
A: It is compatible with high-quality lithium complex greases designed for machine tools. We can pre-pack the bearing with specialized grease according to your RPM requirements.
Q: Can this replace standard angular contact thrust ball bearings?
A: Yes, ZARF bearings often replace multi-bearing angular contact sets, offering far higher rigidity and load capacity in a similar or smaller footprint.
